Abstract:

The paper presents the status of angiospermic flora of Char Kukri Mukri Wildlife Sanctuary, a small Island in the Bay of Bengal close to the Char Fassion Upazila of Bhola district. A total of 277 plant species belonging to 76 families was identified from the Island. For each plant species data on scientific name, local name, family, life form and habitat were provided. Trees of this Island were represented by 91, shrubs by 33, herbs by 118 and climbers by 35 species. The plant species recorded from the island were distributed in different habitats. Among the habitats, maximum species were recorded in homesteads (104) followed by roadsides (79), mangrove areas (47) and cultivated land (47).The study has reported the presence of medicinal plants, wildlife supporting plants, exotics and invasive plants, rare and threatened plants in the Island. The presence of fruit bearing species in the island is very rare because of high salinity. The introduction of exotics and invasive species into the Island has been recognized as the great challenges to the local angiospermic flora in future. This article also highlights the conservation values, management concerns and some measures for conservation of angiosperm diversity in the Island. Asiat. Soc.

Abstract:

The main objective of this review study is to examine various fungal diseases on angiospermic plants which lower plant productivity and worsen the financial situation of flowers. Angiospermic flora are the most useful and marketable plants, employed for the majority of purposes, contributing to a better environment and spreading positive energy, but these flowering plants are presently damaged by unfavourable environmental conditions. The occurrence of fungal infection suppresses the beauty, growth, production and commercial values of flowers and also affect the living beings by increasing air pollution due to the infected plants. Fungicides, chemicals and molecular techniques are already in used to enhances the yield of crops and growth of plants, but still more research needs to be conducted to find the way for increasing the yield and preventing the plants more.

Abstract:

Bhimashankar Wildlife Sanctuary (BWS) is located on the crestline of the northern Western Ghats in Pune and Thane districts in Maharashtra State. It was notified in October 1985 towards conservation of the state animal of Maharashtra, the Giant Squirrel Ratufa indica ssp. elphinstonii. Although an important protected area in the Western Ghats, due to the lack of a comprehensive report, an assessment of floristic diversity of BWS was done from 2009 to 2016. The results revealed that forest types and microhabitats are diverse in the sanctuary. Major forest types are western subtropical broad leaved hill forest to moist deciduous types with a few included small patches of evergreen forests. The rich flora of the sanctuary is represented by a total of 1,142 angiospermic taxa at species and infraspecific level spread over 619 genera and 124 families. Of these 1,094 taxa are wild, which belong to 118 families and 586 genera. Rest of the taxa are planted (34), and 14 introduced. The taxa are classified as per the APG IV. The wild taxa include 20 magnolids, 285 monocots, one Ceratophyllales and 788 eudicots. Out of these, 217 taxa are Indian endemics; which comprise about 19.84% of the total number of wild taxa (1,094) in the sanctuary and 5.04% of total Indian endemics (4,303). Total 53 taxa are under different threat categories according to IUCN. BWS harbours a significant extent of angiosperms in a very small geographic area.

Abstract:

The tendency of intraspecific variation among wild Angiosperms (Flowering plants) has been increasing in the modern times. The reason maybe the climate change, habitat disturbances, geographical isolation. The studies pertaining to the intraspecific taxa is very scanty though they were reported in the classical records (ca. 3000 years). To explore the intraspecific diversity among Angiosperm taxa and find out the intraspecific variations from the Flora of Telangana the studies taken up as part of the doctoral degree. A total of ca. 50 intraspecific Angiosperm taxa reported from the flora of Telangana. Out of them 19 taxa showing the variations in the floral and seed color presented in the present paper.

Abstract:

Angiosperm mesofossils are described from the Lower Cretaceous Almargem Formation exposed near the village of Catefica, Portugal, and are thought to be of Aptian-early Albian age. The mesofossil assemblage from Catefica is diverse and, in addition to the angiosperms described here, also contains a rich assemblage of non-angiosperm fossils, including leafy axes of bryophytes and lycopsids, lycopsid and salvinialean megaspores, and sporangia, sori and leaf fragments of ferns. There are also twigs, cones, cone scales, seeds and sporangia of several kinds of conifers. Other seed plants include 11 species of chlamydospermous seeds and vegetative axes related to the BEG group (Bennettiales-Erdtmanithecales-Gnetales). In terms of the number of plant fragments identified, angiosperms are most abundant in the Catefica assemblage and account for more than half of all specimens. Angiosperms also dominate in number of species, but because the non-angiosperm fossils have not been studied in detail the total number of species in the flora is not yet established. Sixty-seven species of angiosperms are recognized. Angiosperm diversity is mainly at the level of non-eudicots, including ANA-grade angiosperms, Chloranthaceae and magnoliids. Remains of chloranthoid angiosperms are especially common, both in the number of specimens and in number of species recognized. About 40 % of the specimens, and more than 25 % of the species are chloranthoids. Remains of magnoliid angiosperms (Magnoliales, Laurales, Canellales, Piperales) are also prominent among the angiosperms. Eudicots are subordinate: only 3–4 % of all angiosperm specimens can be assigned confidently to eudicot angiosperms. Five new genera and six new species of angiosperms are established (Canrightia foveolata sp. nov., Elasmostemon paisii gen. et sp. nov., Endressistemon cateficensis gen. et sp. nov., Ibericarpus cuneiformis gen. et sp. nov., Proencistemon portugallicus gen. et sp. nov., Valvidistemon globiferus gen. et sp. nov.). Several other new taxa are also described, but not formally named.

Abstract: The present research paper presents a comprehensive floristic study of Deedwana Tehsil, District Nagaur, Rajasthan, aimed at documenting the plant diversity and understanding its ecological significance. The study involved extensive field surveys, specimen collections, and interviews with local experts to identify and classify the plant species within the region. The results revealed a diverse and unique assemblage of plant species in Deedwana Tehsil, representing various vegetation types and habitats. The enumeration of identified plant species showcased a rich floral diversity, including both native and exotic species. A total of 331 species of angiospermic plants belonging to 218 genera and 65 families were recorded including four series of natural vegetation in Deedwana tehsil: 1. Acacia nilotica-Maytenus emarginata-Balanites aegyptiaca series 2. Prosopis cineraria-Crotalaria burhia-Leptadaenia pyrotechnica series. 3. Prosopis cineraria- Capparis decidua-Tephrosia purpuria series and 4. Suaeda fruticosa-Cressa cretica–Heliotropium curassavicum series. (Quereishi, 2018). The study also provide information about the traditional uses of plants by local communities, providing insights into their cultural significance and medicinal applications. Traditional knowledge holders and local healers shared valuable information about medicinal plant practices, adding to the understanding of the region's traditional healthcare systems. The study also analyzed the major threats faced by the flora of Deedwana Tehsil, such as habitat loss, overgrazing, climate change, and unsustainable resource extraction. These findings highlighted the urgent need for conservation and sustainable management initiatives to protect the region's botanical wealth

Abstract:

Late Cretaceous mesofossils are described from the Zliv-Řídká Blana locality in the South Bohemian Basins, the Czech Republic. Angiosperm remains dominate the fossil assemblage both in terms of taxonomic diversity and quantitatively, with about 65 different species based on about 1,000 specimens of flowers, fruits and seeds. There are surprisingly few nonangiosperm species in the flora, with only four specimens assigned to bryophytes, ferns and conifers. There are no megaspores of Selaginellales or Salviniales, which are otherwise common in many Cretaceous mesofossil floras. Among angiosperms, flowers and fruits assigned to the Normapolles group (Fagales) and to the Ericales are particularly prominent. In systematic composition as well as general organization and size of the angiosperm reproductive organs, the Zliv-Řídká Blana mesofossil flora is comparable to other Late Cretaceous mesofossil floras collected from various regions of Laurasia. In addition to the plant remains, the fossil assemblage also includes insect eggs and coprolites.

Abstract:

Plant invasions in tropical ecosystems are being increasingly realized particularly in highly dynamic but fragile dry tropical ecosystems, where there is generally little ecological information on invasions in subterranean vegetation. The present study was carried out to understand the floristic composition of both seed bank and standing vegetation across a range of five diverse anthropo-ecosystems in an urban region in Indian dry tropics. A total of one hundred soil samples (each of size of 25cm×25cm from 0-5 cm and 5-10 cm depth) from five anthropic sites (vegetation of University campus, polluted Kali River bank, Brick kiln, Waste land and Road side) were analyzed for their taxonomic position, life form and bio-geographic origin of the seedling emergents in relation to the flora in standing vegetation. A total of 221 plant species (58% aliens, 34% of aliens of American origin, 75% weedy herbs) in standing vegetation spread over 54 families were recorded in standing vegetation of the study sites with more than 55% representation from eight dominant families led by Fabaceae, Poaceae and Asteraceae followed by Malvaceae, Amaranthaceae and Solanaceae. In contrast, a total of 81 seed bank flora (10 unidentified, 62% aliens, 43% of American origin, 87% herbs) distributed over 32 angiospermic families were recorded. While none of the seed bank vegetation at any site showed significant similarity with its standing vegetation indicating the minor role of seed bank flora in the regeneration of the standing plant communities above ground. However, a considerable similarity among seed banks and standing vegetation at other sites indicated a significant possible role of anthropogenic activities in the urban regions of Indian dry tropics, evinced by the largest proportion of grasses and herbs dominated by exotics, especially of American origin. These aliens through successful naturalization via seed banks may cause homogenization of floristic structure. In conclusion, the present study revealed a heavy scale of intrusion by the alien plants dominated by American elements into not only standing vegetation but also in seed banks across the anthropic sites in urban regions in Indian dry tropics which is likely to alter the standing vegetation floristic structure with a larger abundance of alien flora.

Abstract:

Abstract An Early Cretaceous mesofossil flora is described from the lower part of the Almargem Formation (late Barremian-early Aptian) from Torres Vedras (NE of Forte da Forca), Portugal. The flora is the oldest mesofossil flora containing angiosperm remains to be described in detail based on well-preserved flower, fruit and seed remains. In addition to angiosperms, the mesofossil flora also includes megaspores, sporangia and tiny leaves of spore-bearing plants. There are also twigs, cone fragments and seeds of conifers and seeds assigned to the BEG group. In total about 100 species have been distinguished. Most abundant in terms of plant fragments identified, are spore-bearing plants and conifers. Although only about 18 % of the specimens can be attributed to angiosperms, angiosperm diversity is unexpected high considering the age of the flora. Angiosperms account for about 62 % of all species recognized. Angiosperm diversity is mainly at the level of ANA-grade angiosperms, eumagnoliids and in a few cases early diverging lineages of monocots. Eudicots are subordinate. Twenty new genera and 28 new species of angiosperms are established (Anaspermum operculatum gen. et sp. nov., Appofructus nudus gen. et sp. nov., Appomattoxia minuta sp. nov., Burgeria striata gen. et sp. nov., Canrightia elongata sp. nov., Choffaticarpus compactus gen. et sp. nov., Dejaxia brevicolpites gen. et sp. nov., Dinisia portugallica gen. et sp. nov., Eckhartia brevicolumella gen. et sp. nov., Eckhartia longicolumella sp. nov., Eckhartia intermedia sp. nov., Eckhartianthus lusitanicus gen. et sp. nov., Eckhartiopsis parva gen. et sp. nov., Gastonispermum antiquum sp. nov., Goczania rugosa gen. et sp. nov., Goczania inaequalis sp. nov., Goczania punctata sp. nov., Ibrahimia verminculata gen. et sp. nov., Juhaszia portugallica gen. et sp. nov., Kempia longicolpites gen. et sp. nov., Kvacekispermum costatum sp. nov., Mcdougallia irregularis gen. et sp. nov., Nicholsia brevicolpites gen. et sp. nov., Piercipollis simplex gen. et sp. nov., Reyanthus lusitanicus gen. et sp. nov., Samylinaea punctata gen. et sp. nov., Teebacia hughesii gen. et sp. nov., Vedresia elliptica gen. et sp. nov.). Comparison with results of a palynological study from the same horizon that yielded the mesofossil flora shows a marked underestimation of angiosperm diversity in the palynoflora, a pattern that has also been recognized elsewhere.

Abstract:

New plant fossils collected in 2016 from the Derevyannye Gory Formation on the New Siberia Island are studied. Thirty species of fossil plants are identified and illustrated. They belong to liverworts, ferns, ginkgoaleans, conifers and angiosperms. Sixteen of them have not beed found in the New Siberia Flora before. A new angiosperm species Dalembia (?) gracilis Herman is described. The New Siberia Flora is characterised by a moderately high taxonomic diversity, predominance of conifers and angiosperms with large-leafed platanoids and trochodendroids being the most abundant among angiosperms, by predominance of dentate-margined angiosperms and rarity of plants with entire-margined leaves, and by absence of cycadaleans and bennettitaleans. The flora existed during the Turonian–Coniacian time interval and most probably should be dated as Turonian. Plants of the New Siberia Flora experienced a warm-temperate humid climate with warm summers, mild frost-free winters and insignificant seasonality in precipitation.

Abstract:

The coal and carbonaceous shales collected from the Tura Formation (late Palaeocene) of Nangwalbibra, East Garo Hills, Meghalaya, have been analysed for palynological study to deduce palaeovegetation and palaeoclimate. The palynoflora represented by pteridophytic spores and angiospermic pollen grains shows similarity with other contemporaneous deposits of the Garo, Khasi and Jaintia Hills of Meghalaya. The palynoassemblage dominated by angiosperms depicts subtropical to tropical vegetation during the late Palaeocene in the region. The fossil pollen grains show their similarity with modern plants of various tropical angiosperm families, like Alangiaceae, Anacardiaceae, Annonaceae, Arecaceae, Bombacaceae, Clusiaceae and Gunneraceae, etc. which indicate the existence of tropical evergreen to moist deciduous forest. Some of the taxa resemble the floral elements growing near swamps in the tropical zone. The fossil palynoflora indicates warm and humid climate during the depositional period. The study is supported by plant megafossil data known from the same horizon.

Abstract:

Estuaries are coastal ecosystems which are commonly known to support unique flora and fauna. The Adyar estuary is a severely damaged ecosystem due to developmental activities in the urban city of Chennai, Tamil Nadu, India. Botanical explorations were conducted in and around Adyar estuary during 2008 to 2010 to document the diversity and distribution of angiosperms. A total of 252 species and 2 varieties of angiosperms belonging to 196 genera, distributed in 64 families from 27 orders and 10 clades/groups were recorded and are arranged according to Angiosperm Phylogeny Group III Classification. It is observed that the flora of Adyar estuary also harbours a high level of non-native species. Anthropogenic threats to the estuary and its flora are identified and conservation strategies are briefly discussed.

Abstract:

In the second half of the nineteenth century, pioneering discoveries of rich assemblages of fossil plants from the Cretaceous resulted in considerable interest in the first appearance of angiosperms in the geological record. Darwin's famous comment, which labelled the ‘rapid development’ of angiosperms an ‘abominable mystery’, dates from this time. Darwin and his contemporaries were puzzled by the relatively late, seemingly sudden and geographically widespread appearance of modern-looking angiosperms in Late Cretaceous floras. Today, the early diversification of angiosperms seems much less ‘rapid’. Angiosperms were clearly present in the Early Cretaceous, 20–30 Myr before they attained the level of ecological dominance reflected in some mid-Cretaceous floras, and angiosperm leaves and pollen show a distinct pattern of steadily increasing diversity and complexity through this interval. Early angiosperm fossil flowers show a similar orderly diversification and also provide detailed insights into the changing reproductive biology and phylogenetic diversity of angiosperms from the Early Cretaceous. In addition, newly discovered fossil flowers indicate considerable, previously unrecognized, cryptic diversity among the earliest angiosperms known from the fossil record. Lineages that today have an herbaceous or shrubby habit were well represented. Monocotyledons, which have previously been difficult to recognize among assemblages of early fossil angiosperms, were also diverse and prominent in many Early Cretaceous ecosystems.

Abstract:

Introduction. The flora of the area of study included algae, fungi, lichens and higher plants (mosses, ferns, golonasinny and angiosperm). They play an important role in the ecosystem of the Airport Forest Park. Odesa, create primary organic matter, emit oxygen, dispose of carbon dioxide, enrich the soil with nitrogen substances, decompose the remains of organic substances and process them into inorganic and are food and shelter for many invertebrates (worms, mollusks, insects) and vertebrates (reptiles, birds, mammals) organisms. Aim. The purpose of the work was to study the floristic diversity of the Airport Forest Park in Odessa. Methods. For the first time, the flora of the Airport forest was investigated during 2000-2022 by the route method. Determination of the species composition of algae, fungi, lichens, higher plants was carried out by light microscopy with the help of many determinists, atlases, monographs. Results. The flora of the forest park "Airportivsky" consists of 173 species (173 inland species taxa), which belonged to 156 genera, 60 families, 37 orders, 13 classes, 10 departments, 4 kingdoms and 2 empires (domains). The flora consisted of lower (Thallophyta) and higher (Embryophyta) plants. Lower plants were represented by algae (12 species), fungi (35) and lichens (2), higher – mosses (3), ferns (1), golonosin (6) and angiosperms (114). A characteristic feature of the taxonomic diversity was the dominance of angiosperms (114 species) in the species composition of the flora of the forest park. The most represented species were the leading families Asteraceae (20 species), Rosaceae (13), Fabaceae (11), Brassicaceae (6), Poaceae (5), Oleaceae (5), Aceraceae (4), Fagaceae (2), Lamiaceae (2) and Plantaginaceae (2). Leading genera of Aser l. (4 species), Artemisia L. (4), Agaricus L. (3), Medicago L. (3), Prunus L. (3), Trifoilium L. (3), Closterium Nitsch ex Ralphs (3), Amanita Pers. (2), Lactarium Pers. (2) and Plantago L. (2) formed the basis of the flora of the forest park. The most interesting floral finds are found in the flora of the park of the following species: closterium closteroid (Closterium closterioides (Ralfs) Luns et Peweters), glass Ola (Cyathus olla (Batsch) Pers.). Conclusions. For the first time in the flora of the Airport forest found 173 species (173 inland species taxa), belonging to 156 genera, 60 families, 37 orders, 13 classes, 10 divisions, 4 kingdoms and 2 empires (domains). Among them were found 12 species of algae, 35 fungi, 2 lichens, 3 mosses, 1 fern, 6 gymnosperms and 114 species of angiosperms.

Abstract:

The paper summarises the evolution of angiosperms in different zones of Himalaya. The Himalayan Cenozoic flora has been divided age-wise as Palaeogene and Neogene flora. The Himalayan Palaeogene flora is largely a continuation of tropical peninsular flora of India. The early Miocene flora of Lesser Himalaya is also moist tropical. However, temperate plants started appearing during Miocene in the Higher Himalaya and their occurrence in Plio-Pleistocene flora of Kashmir reflect uplift of the Himalaya. The sub-Himalayan flora indicates existence of warm humid conditions in this belt which became drier by the end of Pliocene. The northern floral elements appeared to have invaded India all along the Himalayan belt. Since its birth the Himalaya has played a significant role in the immigration of plants from the adjoining regions, i.e. east, west and north, thereby enriching the Indian flora. The development of the Cenozoic flora of the Himalayan region is an expression of changing patterns of geography, topography and climate.

Abstract:

The Turonian - Coniacian (Late Cretaceous) Arman Flora (North-eastern Russia, Magadan District) exhibits a high diversity of fossil angiosperms (28 dicot species). Based on their physiognomy, palaeoclimate variables were estimated showing that the flora experienced a humid warm-temperate climate without any pronounced seasonality. Palaeoclimate variables estimated for the coastal plain floras (Penzhina, Kaivayam and Tylpegyrgynai floras, North-eastern Russia) are the same (within analytical errors) as those estimated for the Arman Flora that existed within uplands of the Okhotsk-Chukotka volcanogenic belt. This conclusion implies that the elevation of the intermontane basin of the Arman Flora biotope was not high, presumably not more than 600 m - and not sufficient to be reflected in palaeoclimate experienced by the Arman Flora.

Abstract:

For most of the Twentieth Century the angiosperm archetypal flower has been viewed as relatively large, multiparted, with spirally arranged fleshy appendages, and as being probably beetle pollinated as in some extant Magnoliales. However, the preponderance of fossil evidence indicates that flowers with such characters do not appear until the mid-Cretaceous, well after smaller simpler fossil flowers such as platanoids and chloranthoids. Winteraceous and Chloranthaceous pollen appears more or less simultaneously in the Lower Cretaceous, but rapidly mounting evidence for mosaicism in Cretaceous taxa makes it unwise to extrapolate floral structure on the basis of dispersed pollen. Mid-Late Cretaceous fossils illustrate an increasing proportion of simple flowered Rosidae in the angiosperm flora. We report new fossil evidence of charcoalified flowers and fruits representing at least 20–30 diverse angiosperm taxa from the Cenomanian and Turonian deposits of the Atlantic Coastal Plain. These fossil flowers include representatives with hypanthia and floral cups, sympetaly, syncarpy, inferior ovaries, campylotropous ovules, nectaries of various forms, specialized anther dehiscence, epipetalous stamens, and connate filament tubes. Major taxonomic groups (as defined by Cronquist) represented by these fossils include Dilleniidae, Magnoliidae, Rosidae, monocots, and possibly Caryophyllidae. Thus, the early Late Cretaceous angiosperm flora had greater floral diversity than has previously been documented. This array of floral structures includes features that are now associated with bees and other specialized insect pollinators, thus providing a new perspective on the evolution of insect pollination.

Abstract:

AbstractWater lilies belong to the angiosperm order Nymphaeales. Amborellales, Nymphaeales and Austrobaileyales together form the so-called ANA-grade of angiosperms, which are extant representatives of lineages that diverged the earliest from the lineage leading to the extant mesangiosperms1–3. Here we report the 409-megabase genome sequence of the blue-petal water lily (Nymphaea colorata). Our phylogenomic analyses support Amborellales and Nymphaeales as successive sister lineages to all other extant angiosperms. The N. colorata genome and 19 other water lily transcriptomes reveal a Nymphaealean whole-genome duplication event, which is shared by Nymphaeaceae and possibly Cabombaceae. Among the genes retained from this whole-genome duplication are homologues of genes that regulate flowering transition and flower development. The broad expression of homologues of floral ABCE genes in N. colorata might support a similarly broadly active ancestral ABCE model of floral organ determination in early angiosperms. Water lilies have evolved attractive floral scents and colours, which are features shared with mesangiosperms, and we identified their putative biosynthetic genes in N. colorata. The chemical compounds and biosynthetic genes behind floral scents suggest that they have evolved in parallel to those in mesangiosperms. Because of its unique phylogenetic position, the N. colorata genome sheds light on the early evolution of angiosperms.

AbstractAngiosperms first appeared in the fossil record as pollen during the Valanginian–Hauterivian; they spread out of the tropics in the Aptian and Albian, and radiated in the Late Cretaceous. Despite these general patterns, details of the taxonomic, geographic, and ecological evolution of Cretaceous angiosperms are relatively poorly known because only a handful of Early and mid-Cretaceous macrofloras have been reported. This is the first detailed report of a fossil leaf flora from the Cedar Mountain Formation from the mid-Cretaceous of the Western Interior. We describe a flora that is overwhelmingly dominated by angiosperms (152 of 153 identified specimens are angiosperms) from the Albian–Cenomanian transition that is preserved in a clay- and carbonate-rich, lacustrine mudstone from the uppermost Cedar Mountain Formation of Emery County, Utah. We recognize 18 leaf morphotypes, all of which are dicotyledonous angiosperms. The majority of the Cedar Mountain morphotypes have taxonomic affinities with forms of similar age described from the Atlantic and Gulf coastal plains and other localities from the Western Interior. From this, we infer that a relatively diverse angiosperm flora grew along the margins of a small pond on the coastal plain. Palynological preparations of the fossil matrix were barren; however, previous studies of other facies within the formation showed that both conifers and ferns were important components of the regional vegetation during Cedar Mountain time. The effective absence of conifers and ferns in this macroflora and low leaf mass per area values among the angiosperms measured suggests that even at the Early–Late Cretaceous transition, angiosperms had come to dominate some sites, particularly those that were disturbed or seasonally ephemeral, where fast-growth or seasonal deciduousness would have been favored.

Abstract:

The present article focuses the status of angiosperm flora of Sreenagar upazila under Munshiganj district. The study was done from July 2015 to June 2016. A total of 219 plant species of angiosperms was identified belonging to 165 genera and 70 families. Among them 38 species were monocotyledons and 181 plant species were dicotyledons. Herbs were the largest life forms among the angiosperms and contained about 58% of total plant species occurring in this area. Trees and shrubs occupied 23% and 12% respectively. Climbers were 6% but epiphytes (1%) were very negligible in number in the study area. About 51 medicinal plants were recorded from this study. The following species viz. Lasia spinosa, Calamus tenuis, Tinospora crispa, Passiflora foetida and Calotropis procera were recorded only once and hence considered as rare species in Sreenagar upazila. An invasive poisonous plant Parthenium hysterophorus was also found in Sreenagar. Asiat. Soc. Bangladesh, Sci. 43(2): 161-172, December 2017

Abstract:

Assemblage of fossil plants from the Gydra, Yum and Kananyga Formations (the Villigha and Toomahni Rivers interfluve, Okhotsk-Chukotka volcanogenic belt) are joined in the Aleeki flora. The systematic description of main species is given and floristic and phytostratigraphical analysis of this flora is carried out. New species Lobifolia alikensis Golovn. et Shczep. is described. The Aleeki flora is typical flora of the Okhotsk-Chukotka volcanogenic belt. It contain few angiosperms and significant amount relic elements among ferns (Hausmannia, Lobifolia), cycadophytes (Heilungia), czekanowskiales (Phoenicopsis) and ginkgoales (Sphenobaiera, Ginkgo ex gr. sibirica). In consequence of its stratigraphical position the Aliky flora is slightly younger than the Chingandzha flora (the Turonian-Coniacian) and it is compositionally similar with the Chaun flora (Coniacian). On this basis the age of the Aleeki flora is estimated as the Coniacian. The common taxa of the Aleeki and Chingandzha floras are Coniopteris tschuktschorum, Asplenium dicksonianum, Cladophlebis inaequipinnulata, Birisia sp., Ginkgo ex gr. adiantoides, G. ex gr. sibirica, Sequoia, Metasequoia, Menispermites, Dalembia and Trochodendroides. The common genera of the Aleeki and Chaun floras are Coniopteris, Asplenium, Arctopteris, Cladophlebis, Ginkgo, Sphenobaiera, Heilungia, Phoenicopsis, Picea, Sequoia, Metasequoia, Menispermites, Dalembia and Trochodendroides. Besides that the Aleeki flora contains some species, which were believed as endemic of the Chaun flora: Tchaunia lobifolia, Cladophlebis grandis and Araucarites subacutensis. The Aleeki and Chaun floras are now considered as contemporaneous regional floras, which were distributed in the northern part of the Okhotsk-Chukotka volcanogenic belt.

Abstract:

Resumo No final da década de 1960, pesquisadores do Museu Paraense Emílio Goeldi (MPEG) iniciaram as coletas botânicas na Serra dos Carajás, resultando em um expressivo acervo e interessantes descobertas sobre a flora local, marcada por endemismos e pressão por atividades mineradoras. Em 2014, foi estabelecido o projeto "Flora das cangas da Serra dos Carajás" através da cooperação entre o MPEG e o Instituto Tecnológico Vale de Desenvolvimento Sustentável (ITVDS), visando especialmente a elaboração da flora das cangas da FLONA Carajás. Um acervo de cerca de quinze mil exsicatas, depositadas principalmente nos herbários MG e BHCB além de HCJS, INPA, IAN, NY e RB constitui a base para o desenvolvimento da flora. Até o momento, a flora inclui 151 famílias de angiospermas, gimnospermas, licófitas e samambaias e briófitas (musgos e hepáticas). Neste trabalho apresentamos um breve histórico dos estudos botânicos na região, caracterização da área de estudo, e procedimentos metodológicos adotados no desenvolvimento do projeto. Também, constitui a introdução para o volume 1 da Flora das cangas de Carajás composto por 55 famílias, sendo quatro de briófitas, duas de licófitas, oito de samambaias, uma de gimnospermas e 40 de angiospermas, incluindo 139 gêneros e 248 espécies.

Abstract:

AbstractTufas bearing plant macroremains are uncommon in the Causses Basin (southern France). Here, we report a new fossiliferous tufa deposits at Mende, in Lozère. This palaeontological site is the first Quaternary tufa from the northern part of the Causses Basin that yields such an abundance of plant macroremains. The radiocarbon dating shows that these Holocene deposits are related to the Atlantic period. Geomorphology and mineralogy show that the plant-bearing deposit is a calcareous tufa only composed by calcite, deposited near to an outlet of cool water, linked to the karstic hydrological system of the Causse de Mende. The flora exposed in this article is dominated by angiosperms. Leaves and reproductive structures were assigned to Acer platanoides, Corylus sp., Hedera sp., Salix cf. cinerea, and Tilia cordata. This new palaeobotanical data complements our scarcely knowledge of the Atlantic floras from the Causses Basin. During the Atlantic period, and in the northern part of the basin, whereas Pinus-dominated forests and oak groves were probably well-developed, valleys were locally inhabited by diversified wet angiosperm-dominated forests.
