The megafossil records of monocotyledons assigned to Upper Cretaceous (Maastrichtian) onward from India have been reviewed along with their possible resemblances with the extant members to have a meaningful taxonomic and phylogenetic relationship. The early record of angiosperm megafossils assigned to the dicotyledons is from the Lower Cretaceous horizon of Rajmahal Hills, Bihar (now Jharkhand). A thorough search for the monocotyledons is yet to be made from these beds. The Deccan Intertrappean beds which belong to Maastrichtian (Upper Cretaceous) - Palaeocene age, are very rich in angiosperms comprising both dicotyledons and monocotyledons preserved especially in the form of permineralizations. The later epochs or series, however, are rich in compressions and impressions. The monocotyledonous flora is dominated mainly by palms (Family-Arecaceae) followed by the families of Scitamineae, Poaceae, Cyperaceae and Araceae. In order to understand the early monocotyledonous diversification future work is to be concentrated in the Rajmahal Intertrappeans and contemporary horizons belonging to the Lower Cretaceous Period. Thorough search for entire herbaceous elements, woody juvenile and arborescent members (palms, pandans, aroids, liliales, grasses, Cyperaceae, etc.), reconstructions of entire plants based upon organic occurrences and associations in addition to the isolated reproductive and vegetative organs of taxonomic significance is to be given priority. In depth knowledge of morphology and anatomy of comparable extant flora is required for their phylogenetic assessments.

This article presents results of long-term studies of the meadow flora of the Ketpen-Temerlik ridge within Kazakhstan and China. The article presents an analysis of the meadow floristic complex of the Ketpen-Temerlik ridge. The taxonomic diversity of species composition of meadow floristic complex, biomorphological analysis of life forms of meadow species, and also the belonging of meadow species to different geographical types of areas. A detailed floristic analysis of meadow flora made it possible to identify 624 species of vascular plants belonging to 230 genera and 47 families. According to the main taxonomic groups of plants, the meadow flora is represented by the Magnoliophyta department, which accounts for 82.2% of the total species composition, and only an insignificant percentage is in the Liliopsida department, 17.1%. The ratio of monocotyledonous and dicotyledonous plants in meadow flora is 1: 4.8. The total number of monocotyledons covers 107 species or 17.1% of the total number of species, there are 517 species of dicotyledonous plants or 82.2%. Analysis of the largest families of meadow flora made it possible to identify 16 largest families by the largest number of species, which contain 504 species. Analysis of the species richness of the genera of flora are: Potentilla, Carex, Ranunculus, Taraxacum, Astragalus, Silene, Veronica. The leading genus of meadow flora accounts for 25.1%. The article considers a boreal nature of the meadow flora. The article reveals a large presence among the meadow flora of Ketpen-Temerlik of mountainous middle asian species with an area limited to the territories of Mountainous Middle Asia.

The Angiosperms represent the best known and most diverse group in Senegal. Even though a lot of work has been done to gain a good knowledge of this group, more work remains to be done. The main objective of this work is to contribute to a better knowledge of the class of monocotyledons in Senegal. More specifically, this work seeks to propose a determination key for the families of this class in order to facilitate their identification. Based on bibliographical research, a rough table and a summary table listing the different characters of the vegetative and reproductive systems of the Monocotyledonous family of Senegal were drawn up. These tables made it possible to propose dichotomous keys. This study showed that in the flora of Senegal, the Monocotyledons are distributed in 230 genera and 37 families. This work made it possible to propose determination keys essentially based on the stable characters of the vegetative and reproductive systems of these families.

Data on monocotyledonous geophytes from a recent Victorian flora are compiled and compared with those from California and some other areas of mainly mediterranean climate. Victoria's monocot geophyte diversity of 9&percnt; places it with parts of South Africa and Western Australia in a group of much higher diversity than California and Chile. The Victorian list is dominated by orchids (all with tuberous roots) and that from California by Alliaceae, Calochortaceae and Liliaceae, with bulbs being the predominant storage organ. Only four families of the 17 involved have native species in both California and Victoria. Most taxa in both areas are dormant in summer and grow during the cool season. However, the Amaryllidaceae found in the Sonoran Desert and the driest parts of Victoria are able to grow in the warm season in response to summer rain.

Background. Monocot plants in the flora of Ukraine embrace about 1000 species. The members of this group have various fruit types and ways of dissemination. In this review, the results of the evolutionary-morphological analysis of fruits in monocot plants of the flora of Ukraine and their structural adaptations to dispersal are presented. Gynoecium structure and morphogenetic fruit types in monocots. The features of the inner gynoecium structure and the relation between gynoecium and fruit structure were analyzed, and the main problems of fruit classification were detected. It was revealed that apocarpous fruits are often polymerous or oligomerous, composed of 3–6 one-seeded fruitlets. The species with inferior ovary often develop capsular fruits. One-seeded fruits represent the most reduced variant of the gynoecium structure and fruit wall anatomy, providing few structural traits for analysis. Ecological and functional features of fruits in monocots. The characteristics of dehiscent and indehiscent fruits, as well as adaptations to various ways of dispersal: myrmeco-, endozoo-, epizoo-, anemo-, hydro- and autochory are presented. Dehiscent fruits (follicle and capsule) reveal ventral, dorsal or double, dorsoventral dehiscence. One-seeded fruits and fruitlets are often adapted to hydrochory or anemochory. Trends of evolutionary changes of fruits in monocots. The most diverse fruits are found in low-species taxa of early monocots. Within the monocots, we can observe certain evolutionary trends: incomplete carpel fusion, the occurrence of superior one-seeded fruits and inferior many-seeded fruits. Each of these trends may be evoked by adaptations for pollination in gynoecium at the flowering stage. Conclusions. The present evolutionary morphological and ecological studies of fruits in monocot plants of the flora of Ukraine are impeded by controversial structural types of the gynoecium in some species and a scarcity of data on ways of dispersal of fruits and seeds. The precise carpological and carpoecological investigations of the monocots are desirable for many plants of the flora of Ukraine.

This article focuses on the analysis of synanthropic flora of Samara. It surveys the history of the research of the flora of the city of Samara, and states that it is possible to base the estimation of the ecological condition of the city of Samara on the process and degree of synanthropy. When studying urbanoflorae different authors define the concept of synanthropic flora differently. O.P. Vinkovskaya, E.P. Gnatyuk, and G.S. Antipina, K.V. Kachkin, I.G. Sokolova, T.V. Astakhova, T.A.Terekhina dealt with issues of terminology. The author believes that the synantropic flora consists of adventitious cultivated plants, adventitious ruderal weeds and apofyte types. In the conditions of the increasing anthropogenous change the process of synanthropization of the vegetable cover becomesquite urgent. The article describes the structure of the synanthropic fraction of the urban flora of Samara. The author notes that in the synanthropic fraction the share of monocotyledonous plants has considerably decreased, and that the adventitious species prevail, the flora being made up by forest-steppe boreal, nemoral and multizone plants. In the analysis of the synanthropic component of the flora such indicators as the flora synanthropy index, the adventivity index, index of the apofyteness and the index of cultivation have been calculated. The author comes to the the conclusion that synanthropy causes reduction of the flora variety

Recent data on monocotyledonous geophytes from south-western Australia are compiled and compared with those from other areas of mainly mediterranean climate, especially California, Chile and Victoria, Australia. South-western Australia has a high monocot geophyte diversity of 496 species (7% of an estimated native flora of 7100 vascular species), like Victoria (12%) and the Cape region (14%). As in Victoria, orchids are by far the most important group, with c. 400 species, including those likely to be described once ongoing taxonomic research is completed. South-western Australia has higher geophyte numbers than Victoria in all families considered, but a lower geophyte percentage because of a much higher vascular species total. Among south-western Australian non-orchid geophytes, as in Victoria, the most common storage organ is tuberous roots, followed by corms then bulbs and rhizomes, whereas in California bulbs are by far the most common. The presence of microgeophytes with seed-like storage organs is a special feature seen in several phylogenetically unrelated lineages in the south-western Australian and Victorian geophytic flora, especially on granite outcrops. Divergent phylogenetic history is undoubtedly a major factor underlying striking differences between the monocot geophytes of mediterranean Australia, California, Chile, South Africa and Mediterranean countries. Further studies, particularly on the last two regions, will enable better elucidation of these patterns.

Climate fluctuations in the Quaternary period in significantly influenced the evolution and distribution of plants, which caused to a serious genetic effects and speciation activity [1]. Thus, Central Asia is distinguished by a wide variety of flora, including 9520 species, while 20% are endemics [2]. Great phenotypic diversity of the wild flora in Uzbekistan, numbering about 4400 species of vascular plants is determined by the peculiar climatic conditions, a variety of zoning, altitudinal zones [3]. At the same time, being one of the centers of early diversification of monocotyledonous geophytes, taxonomically complex representatives of this group are not sufficiently involved in phylogenetic studies. This study is a pilot study of the flora of Uzbekistan using DNA barcoding method, that based on sequencing of phylogenetically significant sequences. Four plastid (rbcL, psbA-trnH, matK, trnL-F) and one nuclear (ITS) markers were used for species identification of the genus Tulipa. The results of molecular phylogenetic analysis for 15 species of Tulipa (Liliaceae) using the marker sequence encoding ITS fragment are presented. The successful usefulness of DNA technology for genetic inventory has been demonstrated.

The article provides a systematic analysis of the species composition of plants of the flora of v. Amangeldy, Almaty region. The comprehensive study of regional floras is becoming increasingly important in connection with the implementation of the solution to the problem of studying and preserving biological diversity. Complete information about the composition of the flora of a territory is of great theoretical importance, it allows establishing the structure and Genesis of its components, to identify individual characteristics, to restore the history of formation and trends. This ultimately is the basis of rational use of plant resources and protection of rare and endangered plants, as well as to solve many important economic problems - identifying new sources and resources of medicinal, food, fodder, ornamental and other plants. One of the main characteristics of any flora is its systematic structure, namely the ratio of families, genera and species, on the one hand, and the quantitative indicators of these taxa that determine its wealth, on the other. These indicators are components of a systematic analysis of flora in general and coenoflora in particular, the data obtained using such analysis are important material for comparative floristry. From this point of view, the systematic structure of the flora acquires the significance of one of the essential indicators that characterize the flora in the regional plan. The study of the species composition of the flora is of great importance both for understanding the history of flora and landscapes of the region as a whole, and for finding ways to conserve and use biodiversity under conditions of increasing anthropogenic pressure. Research was carried out by route-reconnaissance method in combination with a detailed study of experimental sites. In the study area – V. Amangeldy was first identified: 112 species from 88 genera and 29 families, with the dominance of the families Asteraceae (24 species or 21.4 %, 17 genera), Rosaceae (15 species or 13.39%, 11 genera), Brassicaceae (11 species, or 9.82 %, 9 genera) from Dicotyledons, and Poaceae (11 genera, 12 species, or 10.71 %) from Monocotyledonous plants. The dominant families account for 62 species, which is 55.36 % of the total number of plant species growing in this territory. Leading genera Artemisia, Potentilla and Rumex. On the territory of the study, 33 forage plant species were identified: Bromus inermis (Leyss.) Holub., Rumex confertus Willd., Trifolium pratense L., Poa bulbosa L., etc. In connection with the degradation of the vegetation cover number of weed plants was 75 species, among which are: Rumex crispus L., Capsella bursa-pastoris (L.) Medik., Cannabis ruderalis Janisch., Lathyrus tuberosus L. and other. Endemic and rare species were not found. The results of the research will serve as a basis for the rational use of the flora of Amangeldy village in Almaty region, as well as for the conservation of biodiversity. Obtained as a result of a systematic analysis of the flora of Amangeldy, it will help to identify the centers of endemism and relict, as well as to solve the issues of the place and role of this flora in a number of other adjacent floras.

Zingiberaceae is a family of monocotyledonous plants consisting of about 50 genera with a total of about 1600 known species of perennial herbs with tuberous rhizomes, distributed throughout tropical and sub-tropical forests. India has rich diversity of Zingiberaceae plants with nearly 200 of the world taxa occurring here. In Maharashtra 11 genera and around 40 species under this family are found in wild and cultivated state. Satpuda hills of Khandesh are lesser known for their wild Zingiberaceae members with only 5 species recorded in earlier floristic studies of the region. Present paper deals with the addition of Zingiber roseum to the flora of Jalgaon district and Khandesh region. The present record of Z. roseum is only the second record of this species from Maharashtra. The study provides a detailed taxonomic description, photographs and relevant information of above-mentioned plant species.

As a result of expeditionary-route studies, the impoverishment of the composition of the segetal flora in maize crops was established when moving from the North-West to the South-East of the Ural region: from 37 species in the forest-meadow and mountain-forest zones to 10 in the steppe zone. Zonal features of the composition of weed communities associated with the hydrothermal gradient consist in the mutual substitution of annual monocotyledonous and dicotyledonous species with a stable contribution of perennial dicotyledons, as well as the replacement of mesophytic weeds with xerophytic species of the same families. A comparison of cross-spectrum herbicides effectiveness in the forest-steppe and forest-meadow zones showed the advantages of a post-emergent preparation with soil effect of Meister Power. In temperate soil fertility in the Southern area of the region, it is economically feasible to use post-emergent herbicides without soil effect, in Northern areas with stable moisture – soil ones.

Araceae is a family of monocotyledonous plants and has been recorded first time since 1789 by A. L. de Jussieu [1]. Kew Science reported 139 genera 4,236 species followed the authorities of Angiosperm phylogeny group (APG IV) [2], instead of 140 genera 4,167 species [3]. Nevertheless, The Genera of Araceae had been reported 125 genera 3,750 species in 2011 [4], but the Global Biodiversity Information Facility has recently reported 5,953 species in more than 230 genera [5]. The accepted genus and species are still be checked correctly by the taxon experts. Araceae in Thailand has been studied and reported by Bangkok Herbarium since 1921 [6]. In 2012, Flora of Thailand Journal, volume 12 reported 209 species in 26 genera, which did not still comprise the genus Lemna, Wolffia and Spirodella in subfamily Lemnoideae [7]. Nowsday, the record of Araceae diversity should be more than in 2012. Araceae is used for food, medicine, industry and decorate place by local people [8].

<p>The present study was aimed at determining the vascular plant species richness of an urban green-space- the Fergusson College campus, Pune and comparing it with the results of the past flora which was documented in 1958 by Dr. V.D. Vartak. For this, the species richness data was obtained by both secondary sources and intensive surveys from 2009–2014. The data from the primary and secondary sources resulted in the documentation of 812 species belonging to 542 genera under 124 families, of which 534 species (65.8%) exists today as compared to 654 in 1958 (net loss of 120 species). Of the 812 species listed, 278 species were observed only during the past, 210 species were exclusively recorded in the current survey and 324 species were observed both, in the past as well as current survey. Arboreal species richness recorded till date (196) in the campus accounts for 40.7% of that of the entire Pune City. Leguminosae and Poaceae were the dominant dicotyledonous and monocotyledonous families respectively and an inventory of all the species recorded is provided. Although the botanical garden over the past years has lost 187 species, it still houses rare species such as <em>Acacia greggii,</em> which has been reported from Maharashtra for the first time. Considering the rapidly changing urban land use in the city, much attention should be paid towards the conservation of these green spaces, for which such studies provide baseline data.</p><div> </div>

Plants of spontaneous flora are in constant competition with culture plants for water, nutrients and other vegetation factors. The degree of weeding was determined in 2014-2016, at four crops - winter wheat, maize, soybeans and peas, cultivated in conventional tillage system and conservation tillage. Temperatures and precipitations registered on the vegetation period in three year had a high influence on the number of weeds found in agricultural crops, so in 2015 there was a smaller number of weeds than in 2014 respectively 2016. Of the species determined in this period is noted for annual dicotyledonous (most of them Chenopodium sp., Veronica sp. and Xanthium strumarium), and among the species of monocotyledonous species Echinochloa sp. and Setaria sp. which are found in all four cultures. In the case of the application of conservative tillage systems there is an increase in the number of weeds compared to the conventional tillage system. The average yields obtained by maize, soybean and peas at application of conservative tillage systems are close to the classical tillage system, the winter wheat yield was higher in the no tillage system than in the classical tillage system.

Field survey was conducted during the summer season of 2011- 2012 to determine the weed flora and weed dominance at the irrigated sites of White Nile State. The State was divided into six irrigated sites from which a total of thirty- five fields were selected and ten quadrates (1m2) from each field were taken randomly. In each quadrate individual weed species were recorded. Field frequency, uniformity and mean field density were also determined for each weed. Fifty five weed species belonging to twenty- four families (three monocotyledonous and twenty- one dicotyledonous) were recorded. Brachiaria eruciformis, Brachiaria reptans, Thunbergia annua and Ipomoea cordofana were the most dominant weed species in most fields. The highest Abundance Index were recorded by Ipomoea cordofana at El Salam and El Dawium counties (208.16 and 116.35), Brachiaria eruciformis at Um Remta and El Gebalen counties (158.80 and 79.23), Brachiaria reptans at Kosti (116.54) and Momordica balsamina at Gezira Aba county (90.06). Brachiaria eruciformis showed the highest MFD and Uniformity at El Salam and Um Remta Counties (19.11 and 80.00), respectively, and highest frequency value was recorded by Ipomoea cordofana (142.86) at El Salam County. The AI which used as weed survey method is to evaluate the weed management strategies and the change of weed species in weed communities through years.International Journal of Environment Vol.4(4) 2015: 45-61

Some species of genus Lepidium of the family Brassicaceae are ruderal plants, and they can grow well on less fertile soils and may have potential as oilseed crops for marginal lands. To develop cultivation techniques for wild species, the reproductive capacity of the species needs to be revealed. The objective of this work was embryological study of two Lepidium species (L. campestre and L. ruderale). As a result of the study, the main features of male and female generative spheres were established. Male generative sphere: The anther is tetrasporangiate and its wall, the development of which follows the monocotyledonous-type, consists of epidermis, endothecium, one middle layer, and glandular tapetum. Predominantly, tetrahedral microspore tetrads form after simultaneous type of microsporogenesis. The mature pollen grains are two-celled. Female generative sphere: The mature ovule is ana-amphytropous, crassinucellate, and bitegmic with unicellular archesporium that functions as a megaspore mother cell without cutting off of parietal cells. The development of the embryo sac follows the polygonum-type development. The embryo and endosperm develop after the onagrad-type embryogenesis. The established peculiarities of the reproductive biology characterize the studied species as sexually reproducing taxa that guarantee the stability of size of their populations. This is important for the conservation of these species as part of the Bulgarian flora biodiversity given their status of valuable medicinal plants. The data obtained will contribute to the knowledge of the embryological characteristic of genus Lepidium. The results contribute to the understanding of Lepidium biology and potential development of Lepidium species as oilseed cash crops for marginal lands.

"Weeds mapping aims to know the segetal floristic spectrum from the point of view of the degree of weed infestation and the frequency of weeds in each crop. Cereals crops are yearly infested by dicotyledonous and monocotyledonous weeds species, annual and perennial, some of them being very harmful, difficult to control and known as dominant weeds or problem weeds. Research carried out in Constanța county, Agigea and Runcu villages, during 2020-2021 years, was concerned with segetal flora assessment. The main purposes considered were: the study of the issues related to the floristic composition, the dynamics of the degree of weed infestation, the identification of the dominant species, the establishment of the most effective herbicide treatments and of the optimal times of application. The analysis of the obtained data reveals that the problem weeds with a density >10 plants/m2 identified in the wheat and barley crops in Agigea were: Veronica species, Papaver rhoeas, Chenopodium album, Polygonum convolvulus and Fumaria officinalis. The dominant weed species in wheat and barley crops of Runcu were: C. album, Convolvulus arvensis, Stellaria media, Equisetum arvense and Cannabis ruderalis. Although the dicotyledonous species prevail in both studied places, the weed control strategy is different because the target species against which control measures must be applied are different and consequently the range of herbicides will also be different. The results obtained fully justify the weed mapping action because it is a tool that offers the farmer the exact perception regarding the degree of weed infestation in the studied areas. Mapping thus becomes a very useful work for weed control practice."

The The Poti River Canyon State Park (24,772.23 ha), located in the municipality of Buriti dos Montes, is an important Conservation and Environmental Protection Unity in the State of Piauí. Therefore, this research purpose was to identify the angiosperms species which occurr in rocky outcrops in the aforementioned Park. The collection, herborization, identification and classification of specimens was followed the usual specialized literature. The specimens are deposited in the Herbarium Prof. Aylthon Brandão Joly, located on the Center for Superior Studies of Caxias, CESC / UEMA. The park's angiosperm flora is composed by the 96 species, distributed in 82 genera and 34 families. Among these, 85.4% (82 spp.) are eudicotiledonous and 14.6% (14 spp.) are monocotyledonous. The richest families in number of species were Fabaceae (21 spp.), Apocynaceae and Cactaceae (6 spp.); Bignoniaceae and Euphorbiaceae (5spp); Araceae, Anarcadiaceae, Boraginaceae, Cyperaceae and Malvaceae (4 spp.); Bromeliaceae and Rubiaceae (3 spp.), which together had a total of 71.9% of the species, while the others presented between one and two species (28.1%). For this study area, 8.3% (8 spp.) was the firts records for Piauí state, they are Astrocaryum vulgare Mart., Cyperus pohlii (Ness) Steud., Cryptostegia madagascariensis Bojer, Cordia oncocalyx Allemão, Ibatia ganglinosa (Vell.) Morillo, Piptadenia retusa P.G.Ribeiro, Seigler & Ebinger, Vitex gardneriana Schaue e Waltheria operculata Rose as its representants. 14,6% (14 spp.) are endemic to the Caatinga and 5,2% (5 spp.) are new species records for it. This is the first floristic study for the municipality, which contributes with important information to the area of rocky outcrops, increasing the occurrence and the geographic distribution of the species in Brazil.

The flora of vascular plants in the city of Abakan (Republic of Khakassia, Russia) is represented by 459 taxa belonging to 69 families and 325 genera. Angiosperms are predominant in the flora of higher vascular plants and are represented by 451 species (98.3% of the entire city flora), including monocotyledons (104 species, 22.7%) and dicotyledons (347 species, 75.6%). According to these indicators, the flora of this city belongs to temperate floras of the Holarctic. The presence of 24 single-species families in the Abakan flora is related to the observed poor state of environment-forming factors, which prevents the adaptation of species under the new transformed conditions of the urbanized environment. Lichens in Abakan are represented by 33 species affiliated with 18 genera and 8 families. There are 125 mushroom species belonging to 75 genera, 34 families, 6 orders, and a single class, Agaricomycetes.

The paper presents the results of the study on the influence of various tillage systems on the weed infestation of soft spring wheat of the Siberian Alliance variety. The study was carried out in a long-term stationary experiment (20152019) preceded by bare and green-manured fallow (rapeseed, melilot) in Kemerovo region. The soil of the experimental plot is classified as leached, medium-textured, medium-humus, heavy-loam chernozem. The following soil tillage systems were studied: deep moldboard, deep combined, minimum combined and minimum moldboard. Weather conditions during the research period were varied. Insufficient water supply during the first vegetation period of soft spring wheat (seedlings – leaf-tube formation) was noted in 2015-2017, with HTC (hydrothermal coefficient) being from 0.37 to 0.56. Excessive water content was observed in 2018 (HTC = 2.41) and moderate hydration – in 2019 (HTC = 1.12). Weed infestation was different in the conditions of each year. The impact of the soil tillage system on the number of weeds during the growing season of common spring wheat accounted for 21.6-90.4%, and their share in the total aboveground mass of the phytocenosis was 39.9-68.3%. The segetal flora in soft spring wheat crops is represented by monocotyledonous and dicotyledonous species with all the studied tillage systems. The highest density of weed vegetation during the tillering phase of soft spring wheat was recorded with deep moldboard soil tillage system (control). A reduction in weed infestation by 2.3 times compared to the control was noted with minimum moldboard soil tillage system preceded by bare fallow, 1.6 times – preceded by green-manured fallow with rapeseed, and 1.7 times – preceded by green-manured fallow with melilot. The same trend was observed in the proportion of weeds in the total aboveground mass of the phytocenosis during the wax ripeness phase of soft spring wheat with deep moldboard tillage system (4.3%), deep combined (3.9), minimum combined (4.1), minimum moldboard (2.6%).

Abstract Peanut (Arachis hypogaea L.) is the most popular legume cultivated for food and cash in the Guinea and Sudan savannah ecologies of northern Ghana. A three-year survey was conducted between 2003 and 2005 to: (1) document the prevalence of weed species, (2) determine current cropping systems and weed management practices, and (3) assess the response of peanut to weed management practices. Flora with more than 5% dominance included: (1) the dicotyledonous weeds, Corchorus olitorius L. Commelina benghalensis L., Commelina diffusa Burm., f, Desmodium scorpluras (Sw.) Desv., Hyptis suoveolens Poit., Mimosa invisa Mart., Mimosa pigra L., Mitracarpus villosus (Sw.) DC., Oldenlandia corymbosa L., Phyllanthus amarus Schum. & Thonn., Scoparia dulcis L., Tridax procumbens L., Triumfeta cordiflora A. Rich., and Vernonia galamensis (Cass.) Less.; (2) the monocotyledonous weeds Axonopus compresus (Sw.) P. Beauv., Cyperus esculentus L., Cyperus rotundus L., Digitaria horizontalisWilld., Eragrostis tremula Hochst. Ex Steud., Hackelochloa granularis (L.) O. Ktze., Kyllinga erecta Schumach. Var., Kyllinga squamulata Thonn. Ex Vahl., Paspalum scrobiculatum L., Rottboellia cochinchinensis (Lour.) Clayton, and Setaria pallide-fusca (Schum.) Stapf. & C.E. Hubbard; and (3) the parasitic weed Striga hermonthica (Del.) Benth. Land preparation practices included the use of tractors, followed by use of livestock, and lastly hand preparation. Cropping systems consisted of cereals preceding peanut, peanut preceding peanut, and intercropping peanut with sorghum (Sorghum bicolor L. Moench.), millet (Pennisetum Americanum L.), or corn (Zea mays L.). Genetically-improved peanut cultivars expressing bunch or erect growth habits were the most common cultivars although some farmers planted local cultivars expressing a distinct runner growth habit. The majority of farmers planted peanut from early June to early July based on rainfall pattern. Eighty-eight percent of peanut fields were hand weeded once, 3 to 5 weeks after planting (WAP) or twice, 2 to 3 and 5 to 6 WAP. Weed management was generally poorly timed and insufficient to prevent significant weed interference resulting in total oven-dried weed biomass ranging from 600 to 2400 kg/ha at harvest. Peanut haulm production ranged from 500 to 5500 kg/ha with improved cultivars. Pod yield production ranged from 200 to 1680 kg/ha. Results from this survey revealed the need for accelerated research and capacity building of farmers and agricultural extension agents for improved technology transfer to the peanut industry in the region.

Turkey is among the richest countries in the world in terms of plant diversity. The aim of this paper is to show diversity of the petaloid and bulbous plants, which belong to monocotyledones. According to Flora of Turkey and its supplements, the number of species of bulbous monocotyledones is around 688, of which 244 are endemic (endemism 35.4 %). According to the statistical data of Turkish flowering plants based on the published records, only 15 % of the flora have information about chromosome counts, although bulbous monocots percentage is higher at 58 %. Fritillaria and Tulipa are stable genera as regards chromosome numbers with 2n = 24 and karyotype; on the other hand, the most variable genera are Crocus (2n = 6, 8, 10, 12, 14, 16, 18, 20, 22, 26, 28, 30, 70) and Ornithogalum (2n = 12, 14, 16, 18, 20, 21, 24, 27, 28, 32, 40, 45, 54, 60, 80).

This paper reports a quantitative survey of the composition, diversity and structure of the plant communities on six islands of Uyuni and Coipasa salt lakes (Bolivia). Plant communities on each island were examined via the use of 10 transects, along which species richness and abundance were recorded. Seventy-one species were found in total, representing pteridophytes (6%), gymnosperms (1%), monocotyledons (14%) and dicotyledons (79%). About 21% of the species were endemic or faced some degree of threat. The calculation of Shannon-Wiener α-diversity indices and comparisons of community structure revealed similarities between the islands. Indeed these analyses suggest the existence of a single floral assemblage; however, small differences in the plant communities were visually identified during fieldwork. These islands are home to a considerable subset of the Altiplano’s flora and appear to have been little disturbed. They should therefore be the subject of surveillance/conservation programs.

Le niébé (Vigna unguiculata [L.] Walp.) est l’une des principales cultures du bassin arachidier sénégalais. Il joue un rôle important dans les programmes de sécurité alimentaire et dans les stratégies de développement socio-économique du pays. Toutefois, plusieurs contraintes (maladies, ravageurs, pression des adventices, etc.) entraînent des baisses de rendements de cette spéculation. Il est donc important, de trouver des solutions adéquates à ces contraintes ce qui passerait par la connaissance des agents responsables. C’est pourquoi cette étude était entreprise pour contribuer à l’amélioration de la production du niébé par la caractérisation de la flore adventice du niébé. Pour ce faire des inventaires ont été effectués dans les parcelles de niébé dans la zone de Niakhène en appliquant la méthode du « tour de champ ». Ceci a permis de recenser 92 espèces réparties dans 67 genres et 29 familles. Cette flore est dominée par les dicotylédones avec 76,09% des espèces recensées contre 23,93% de monocotylédones. Les familles dominantes sont les Fabaceae et les Poaceae avec respectivement 21,74% et 16,30% des espèces. Les thérophytes (77,17%) sont largement dominantes suivies des phanérophytes (16,30%). Les géophytes, les chaméphytes et les parasites regroupent respectivement 3,26%), 2,17% et 1,09% de la flore. Au plan biogéographique, les espèces Africaines sont plus importantes avec 41,30% de la flore suivies des espèces Pantropicales avec 28,26%. Cowpea (Vigna unguiculata [L.] Walp.) is one of the main crops of the Senegalese groundnut basin. It plays an important role in the country’s food security programs and socio-economic development strategies. However, several constraints (diseases, pests, weed pressure, etc.) lead to yield reductions in this crop. It is therefore important to find adequate solutions to these constraints, which would require knowledge of the agents responsible. This study was undertaken to contribute to the improvement of cowpea production by characterizing the cowpea weed flora. Inventories were carried out in the cowpea plots in the Niakhène area using the « field tour » method. This made it possible to identify 92 species distributed in 67 gendera and 29 families. This flora was dominated by dicotyledons with 76.09% of species recorded against 23.93% of monocotyledons. The dominant families were Fabaceae and Poaceae with 21.74% and 16.30% of species respectively. The therophytes (77.17%) were largely dominant followed by phanerophytes (16.30%). The geophytes, the chamaephytes and parasites group represented 3.26%, 2.17% and 1.09% of the flora, respectively. At the biogeographical level, African species are more important with 41.30% of the flora, followed by Pantropical species with 28.26%.

The article presents a taxonomic, biomorphological, geographical analysis of the biodiversity of the flora of herbaceous species of pine forests of the Irtysh region, which is represented by 168 plant species belonging to 116 genera and 42 families. Analysis of the largest flora families of herbaceous species shows that the dominant communities are Artemisia L. — Festucaria Heist. ex Fabr. and Artemisia L. — Poaceae Barnhart (Artemisia L., Festuca Heist. ex Fabr., Stipa capillata L.) phytocenoses. In all the studied sites, the following plant species are dominates or codominants of Festuca rupicola Heuff., Agropyron cristatum (L.) Gaertn., Stipa capillata L., Artemisia vulgaris L., Carex supina Willd. ex Wahlenb., Spiraea hypericifolia L. The flora is based on angiosperms, including dicotyledons — 137 species (81 %); monocotyledons — 28 species (16.6 %). Gymnosperms are represented by two species of Pinus sylvestris L., Juniperus sabina L., and there is also one species of Eguisetum arvense L. horsetail. The richness of the flora is also emphasized by some quantitative indicators of its taxonomic composition: the average species saturation of one family is 4, the maximum is 36. There are 9 rich families with the number of species above the average (21.4 % of the total number of families), and 22 the poorest, single — species families (52.3 %). The top ten leading families contain 71 % of the total floral diversity. The high level of floristic diversity of the studied territory is due to the variety of ecological conditions of plant habitats (the valley of the Irtysh River with a high variation in moisture and salinity, a variety of rocks of the adjacent riverside uplands) and anthropogenic activities leading to an increase in weed and adventitious plant species.

This study provides basic taxonomic data on Liliopsida (monocotyledons) and Pteridophyta of the representative homestead areas of Dhaka, Gazipur, Manikganj and Tangail districts of Bangladesh. The monocotyledons and pteridophytes, growing naturally in the homstead areas, are composed of total 137 and 16 species under 84 and 13 genera belonging to 22 and seven families, respectively. A total of 20, 13, 19 and 17 species respectively, occur exclusively in the homesteads of Dhaka, Gazipur, Manikganj and Tangail districts and only 22 species are common there. Poaceae with 53 species is the largest family and Cyperus with 12 species is the largest genus in monocotyledons. Pteridaceae with eight species and Pteris with three species are the better represented family and genus, respectively in pteridophytes. Total 136 species are appeared as herbs that are followed by 11 species of trees and six species of shrubs. A total of 119 species are documented as economically useful. This study identifies a number of active threats to the flora of the study area, and suggests to launch adequate management and awareness building programs for the homestead people in order to ensure effective conservstion and sustainable use and development of plant genetic resources in the homestead areas of this region.

The characterization of the messicole flora of the cereal fields conducted under center pivots in the region of Ouargla was carried out from 96 floristic records in experimental plots distributed over the entire surface of the different pivots chosen for our experimentation and this throughout. The phenological development cycle of the planted crop. The total weed flora inventoried includes 52 species classified into botanical families, classes, biological groups and origins. The composition of the weeds is characterized by the dominance of the introduced messicoles, compared to the spontaneous species, provided essentially by the Poaceae (monocotyledons), botanical family and class characteristic par excellence of the weed flora of our study region. There is also a dominance of Asteraceae and Brassicaceae botanical families in disturbed environments. Therophytes were par excellence the most contributory species to the specific richness of the weed flora of the study region.

The Quiçama National Park (PNQ), located in Luanda Province, Angola, is one of the oldest protected areas in the country. Although some work has been done on the flora of the Park, up to now a comprehensive record of the vascular plant species has been lacking. The objective of the present study was to produce an inventory of the vascular plant diversity of PNQ, as well as to record the types of vegetation in which each species occurs, their habits, uses by local communities, common names, and conservation status. A total of 452 species were recorded, from 285 genera and 85 families. Two species are Pteridophytes, 99 are Monocotyledons, and 351 are Dicotyledons. The two largest families of the PNQ flora are the Fabaceae and the Poaceae. The Park hosts 14 species endemic to Angola, and one of them is restricted to this protected area. Of the 128 species with data on conservation status, 109 are considered of least concern, 13 are vulnerable, and six are endangered. Regarding useful plants, 237 species from 67 families were recorded. Of these, 196 are Dicotyledons and 41 are Monocotyledons. Most of them are used for medicinal purposes, the manufacturing of artefacts, and as sources of food.

The Setiu Wetlands, a unique area with nine interconnected habitats, comprises a considerable fraction of the total Peninsular Malaysia’s wetland flora. Although botanical collecting in the area has been active in the past 10 years, only a few studies dealing with the wetland flora have been published. Thus, a detailed checklist of this area is urgently needed to ensure the continuity of its inter-relating flora and fauna, as well as the livelihood of the local people. In this work we conducted a survey of the vascular plant flora of Setiu Wetlands and investigated the most important plants used by the local communities. Our checklist accounts for 406 taxa from 277 genera and 106 families, including 24 (6%) species of ferns and lycophytes, three gymnosperms, 257 (64%) dicotyledons and 122 (30%) monocotyledons. This comprehensive plant checklist will be a primary reference for the management of the newly gazetted Setiu Wetlands State Park covering more than 400 hectares of lands and water bodies.

Abstract This study aims to investigate the coastal plant biodiversity status of Tripoli Province. The result of the survey led to a collection and identification of 130 plant species belonging to 36 families and 105 genera, of which 29 species represented monocotyledons and 101 dicotyledons. Floristic analysis revealed the dominance of the family Asteraceae (24 species) followed by the family Poaceae (22 species). The results have also showed the predominance of the genera Juncus and Lotus with 4 species each. Life form and chorological spectra analyses showed the prevalence of therophytes, represented by 77 species, and the Mediterranean chorotypes with 46 species. Categorization of collected plant species according to their ecological types, revealed a variety of ecological types, with the prevalence of psammophytes, represented by 50 species.
