Résumé :

In order to explore their orchid flora, we performed surveys of 96 Azerbaijani burial places in 2018 and 2019. Altogether, 28 orchid taxa were found in 37 visited cemeteries. In the orchid diversity a remarkable pattern was observed: geographic latitude was significantly and positively related to the number of taxa and number of individuals. The most widespread and abundant orchids in Azerbaijani graveyards were Anacamptis pyramidalis and A. papilionacea (found in 23 and 8 cemeteries, respectively). Azerbaijani cemeteries can be important refuges for rare and threatened orchids, e.g., Himantoglossum formosum (three cemeteries), Ophrys sphegodes subsp. mammosa (eight), Orchis adenocheila (two), O. punctulata (three), O. stevenii (one) and Steveniella satyrioides (one). Epipactis turcica, detected in a single locality, was previously unknown to the flora of Azerbaijan. Additionally, we documented orchid tuber (salep) collection in two cemeteries.

Résumé :

Bonjol District, West Sumatra has a very high diversity of flora, one of the flora found in Bonjol District is orchids (Orchidaceae). However, there is no data that explains the diversity of orchid plants in Bonjol District, so researchers are interested in using this as research. This research aims to find out what types of orchids are found in Bonjol District, the diversity index of orchid plants (Orchidaceae) and the dominance index of the most dominant orchid plants in Bonjol District, West Sumatra. The research was carried out using an exploratory method with direct observation of orchid plants in the field. The sampling method used was purposive sampling, namely taking samples with certain considerations. Sampling was carried out at 2 stations, namely residential areas and forests. Data analysis used the Shannon-Wiener diversity index. The research results showed that the diversity of orchid species (Orchidaceae) in Bonjol District, West Sumatra was classified as moderate, with a total Shannon-Wiener diversity index H' = 1.4117. In Bonjol District, West Sumatra, there are 31 types of orchids from 17 genera, the most frequently found species are Bulbophyllum gibbosum with 35 individuals, while the species found least frequently are Nervelia crociformis and Eria discolor, each with 2 individuals. Then, in the results of calculating the dominance index value for orchids (Orchidaceae) in Bonjol District, West Sumatra, the result was D= 0.044, which means that no species dominates.

Résumé :

Abstract This work aims to better to know the floral richness of Tell region (Saida, western of Algeria) particular orchid flora. This inventory was started in 2017-2022; It’s based on random samples, in spring and autumn. The surveys directly targeted open areas (Northern Saida). This inventory revealed the presence of 11 orchids including 2 species, 6 subspecies and 2 varieties. The 11 taxa belong to 5 genera: Anacamptis, Dactylorhiza, Himanthoglossum, Orchis and Ophrys. Some taxa are rare, endemic and are protected (threatened) by the IUCN Red List as a near threatened species and/or are endemic and protected in Algeria, rare species in the Tell region. A stationary precision made it possible to know the distribution area of each identified taxon. Due to anthropogenic threats, a strategy to protect habitats seems very urgent.

Résumé :

Abstract Orchids constitute an important component of the Pieniny Mts. flora. The presence of 35 orchid species has been noted so far in this region. A considerable number of these species are endangered for various reasons. Eight species have been deemed extinct in the area. On the other hand, the orchid flora of the Pieniny Mts. includes species that widen their local ranges and can, thus, be considered expansive as well as new species, recently entered in the list of orchids occurring in the said mountain range (Epipactis microphylla and Epipactis muelleri). It is necessary and important to conduct an inventory of Pieniny orchid resources (the major aim of this study) that would be repeated at certain intervals, in order to know the number of stations and of individuals per population of each species, which would enable taking relevant actions needed to prevent the disappearance of these plants from the Pieniny Mts.

Résumé :

East Macedonia (northeast Greece) is a relatively small part of Greece, where a considerable number of orchid taxa occurs. Some of these orchids can only be found there and this fact makes the specific area of Greece unique. In this study, an up-to date database of orchid records was used to assess the effectiveness of the existing Natura 2000 network. Specifically, the effectiveness of the Natura 2000 network was evaluated by identifying the number of orchids whose distribution is overlapping to a lesser or greater extent with the network, which chorological categories are included/excluded from it, and whether the rare and threatened orchid taxa are adequately distributed within that. Out of the 73 orchid taxa recorded in East Macedonia so far, 14 taxa are exclusively distributed outside the Natura 2000 network. Specifically, the Natura 2000 network is not overlapped with a number of Balkan and Mediterranean orchid taxa, which are only sparsely found in East Macedonia. Moreover, most of the orchid taxa that have been classified in the threat categories of the IUCN are distributed within the Natura 2000 network of East Macedonia, and specifically, some of the most threatened ones are almost exclusively distributed within that network. Consequently, although the Natura 2000 network is not congruent with the distribution of a number of species of southern origin, which are widely distributed elsewhere in Greece, it can conserve important floristic elements of Greece, which are orchid taxa of northern or central European origin.

Résumé :

Odisha is endowed with very rich and diverse floristic wealth. Its unique geographic location and varied topography enables it to harbor different types of plant communities of which the orchids deserve special mention due to its horticultural as well as commercial importance. Nevertheless, the orchid flora of Odisha is moderately rich but on the other hand it emphasizes upon some important ecological niches. Many rare and endemic orchid species have been reported from the Odisha state like Habenaria panigrahiana var. parviloba, Cirrhopetalum panigrahianum and Eria meghasaniensis which are new to the science. In the endemic category, Pomatocalpa decipiens and Malaxis purpurea are important being recordedonly from Odisha in India. The orchids of Odisha have undergone severe biotic pressure resulting in rapid shrinkage of this rare and interesting plant group. Hence the conservation of Orchid flora of Odisha is need of the hour. Field studies revealed that for effective conservation of the species, conservation of the habitats in which the species dwell is most vital as well as a pre-requisite. Keeping in view the above mentioned facts, the present communication highlights about the ecology of the orchids of Odisha which act as a baseline data before planning any conservation measure and cultivation of orchids as well. Concurrently some conservational strategies have also been suggested.

Résumé :

According to the results of the study, 14 species of orchids were found in the flora of the southern Altai in2019, which is 52 % of the species diversity of the Orchid flora of Kazakhstan. It is established that the coenopopulationsof orchids in the region develop and exist within the boundaries of specific phytocenoses and are characterized by a certainecological and phytocenotic amplitude of the development of natural environment conditions. They are distributed in thelower, middle and upper mountain zones. The widest altitude range is typical for species from the genus Dactylorchiza(absolute altitude 462–1365 m). In terms of life forms, species with a stem-like tuberoid (genera Dactylorhiza, Herminium,Orchis) predominate, while short-rooted and long-rooted species (genera Cypripedium, Epipactis) are less represented. InKaton-Karagai district, 10 species of orchids were recorded growing in 19 cenopopulations, in Kurchum – 5 species in 6cenopopulations. Vegetation cover in habitats is formed from 35 to 90 %. Due to the weak competition of orchids, theirshare in the addition of phytocenoses does not exceed 2 %.

Résumé :

Lampung Indonesia is one of the provinces on the island of Sumatra, which has a flora conservation area located in Liwa Botanical Garden, West Lampung Regency. One of the flora species in the area with a high level of diversity is the orchid plant. The Dendrobium is the largest orchid species, where the public widely hunts this orchid for an economic reason due to the beauty of its various flower shapes and colors. Given the high level of human encroachment, this can threaten the existence of natural orchid plants, causing loss of their original habitat and causing the extinction of orchid species. Based on data in Liwa Botanical Garden, there has been no further identification of natural orchids as a plant conservation effort. To protect and immediately save these natural orchids, it is necessary to identify the Dendrobium orchid species based on the leaf morphological approach. This research will be conducted in April-September 2020. Observations of leaf morphology include leaf shape, leaf tip shape, leaf base shape, leaf edge, leaf reinforcement, leaf arrangement, leaf surface texture, leaf symmetry, and leaf sitting based on guidelines for ornamental plant characterization books. Observations as secondary data were added to the character of the pseudobulb shape and orchid habitat. Observations as secondary data were added on the habitat character of pseudobulbs and orchids. The implementation of this activity is still in the period of the Covid-19 pandemic, so most of the activities are carried out online. The coaching and training phase was conducted through internal virtual discussions on Tuesday, July 7, 2020, while the coaching phase was conducted through meetings or verbal communication via telephone groups and WhatsApp. Based on the evaluation data, it is known that there is an increase in knowledge and understanding of training participants by 21.64 points. The percentage increase in value before and after training is 34.72%. Orchid-related activities at Liwa Botanical Garden were never carried out, thus imparting knowledge to Liwa Botanical Garden technicians and workers on the development of natural orchid identification methods based on the morphological character in local natural resource conservation in the 4.0 industrial revolution era.

Résumé :

Plants are the bedrock of life on Earth but are increasingly threatened with extinction. The most cost-effective way of conserving plant diversity is through Protected Areas (PAs). However, the locality, size, and management of PAs are crucial for effectively maintaining diversity and have been criticized as currently inadequate. Using Armenia as our study site and orchids as our study taxa, we sought to (1) identify spatial patterns of orchid diversity hotspots and corresponding PA network sites; (2) examine if the current PA network is effective at capturing orchid species richness and diversity and (3) explore the relationship between the range of area suitability of species and level of protection. We used data collected from herbarium, field visits and GBIF occurrence records. Using freely available mapping software, we created heatmaps of observations and species richness. We compared PA sites based on the number of species (species richness) and diversity (Shannon–Weiner Index). Species range was developed using the MaxEnt model and a correlation analysis was performed against the proportion of the range within PA. We found that 57% of PA sites have a representation of at least one species of orchid, but some threatened species are not presented within any PA site. The Tavush and Syunik province not only held the highest species richness (>10 species), but the PA network within also held high orchid diversity (2.5 diversity index value for Dilijan National Park). We did not find a significant relationship between the range of area suitability for orchids and protection; however, all our target species had less than 30% of their range under protection. Our study highlights important challenges related to the limitations of available data, and we discuss these implications towards effective conservation outcomes for orchids for the region.

Résumé :

A preliminary checklist of the Orchidaceae of Gashaka Gumti National Park (GGNP) is presented, based on previous reports on the flora of GGNP and recent botanical explorations. The results from this study recorded 80 orchid species in 38 genera. The collection consists of 84% epiphytes and 16% terrestrial orchids. The genera with highest number of species are the Bulbophyllum (16 species) and Polystachya (11 species), while Habenaria is the richest terrestrial genus with five species. Afropectinariella gabonensis, Bulbophyllum renkinianum and Rhipidoglossum polydactylum are newly recorded for Nigeria. Other noteworthy taxa include Angraecopsis elliptica, Bulbophyllum calvum, Holothrix aphyllaand Tridactyle tridentata which are some of the rarest orchid species in Nigeria. The highest species number was recorded in the lowland forest of the southern sector, particularly Kwano, with 42 species, followed by 29 species in the montane forest, five species in the savanna woodland, and four taxa in the lowland gallery forest. Our study identified recent transhumance to the enclave of the park (leading to grazing), and illegal logging of Pterocarpus erinaceous and Afzelia africana as the major noticeable threats to the continued existence of orchid species in GGNP. Therefore, further inventories with rigorous techniques such as the tree climbing technique are warranted for an exhaustive inventory and effective conservation of the orchid flora of GGNP.

Texte intégral

Résumé :

Understanding temporal changes in the distribution and abundance of various species is one of the key goals of conservation biology. During recent decades, the abundance and distribution of many species of plants and animals have declined dramatically, mainly because of habitat loss and fragmentation. The purpose of this study is to analyze the rate of extinction of orchids at various sites in different 20-year time intervals over the last 150 years, determined according to changes in society. Using the dataset of the orchid records of the Nature Conservation Agency of the Czech Republic, we determined the disappearance rate of orchids from sites using a grid of 1 × 1 km. We found that the vast majority of orchids disappeared from many of their historical localities in all time intervals analyzed. The number of sites suitable for Czech orchids declined by 8–92%, depending on the species. The most threatened orchid species in the Czech Republic are Spiranthes spiralis, Anacamptis palustris, Epipogium aphyllum and Goodyera repens. This all seems to be closely related with changes in agricultural practices in the open as well as in forest habitats. Preserving suitable orchid habitats seems to be the key for keeping Czech orchid flora alive.

Bali and Lombok are well known as popular touristic destinations. Both islands are accessible for potential floristic research, but surprisingly, information on their orchid flora is rather scarce and random. During our visits, among other orchid groups, we had an opportunity to observe several representatives of the tribe Malaxideae, which is considered to be one of the biggest and most interesting orchid groups with over 1700 taxa (including synonyms). In this paper, we present the first attempt at organizing the knowledge about these unique, often underestimated, orchids in Bali and Lombok, and we report several new records for both islands. For Bali, there are six from the genus Crepidium and four from Liparis sensu lato, and for Lombok, one from Crepidium and three from Liparis sensu lato.

Résumé :

Abstract Background As in most land plants, the roots of orchids (Orchidaceae) associate with soil fungi. Recent studies have highlighted the diversity of the fungal partners involved, mostly within Basidiomycotas. The association with a polyphyletic group of fungi collectively called rhizoctonias (Ceratobasidiaceae, Tulasnellaceae and Serendipitaceae) is the most frequent. Yet, several orchid species target other fungal taxa that differ from rhizoctonias by their phylogenetic position and/or ecological traits related to their nutrition out of the orchid roots (e.g. soil saprobic or ectomycorrhizal fungi). We offer an evolutionary framework for these symbiotic associations. Scope Our view is based on the ‘Waiting Room Hypothesis’, an evolutionary scenario stating that mycorrhizal fungi of land flora were recruited from ancestors that initially colonized roots as endophytes. Endophytes biotrophically colonize tissues in a diffuse way, contrasting with mycorrhizae by the absence of morphological differentiation and of contribution to the plant’s nutrition. The association with rhizoctonias is probably the ancestral symbiosis that persists in most extant orchids, while during orchid evolution numerous secondary transitions occurred to other fungal taxa. We suggest that both the rhizoctonia partners and the secondarily acquired ones are from fungal taxa that have broad endophytic ability, as exemplified in non-orchid roots. We review evidence that endophytism in non-orchid plants is the current ecology of many rhizoctonias, which suggests that their ancestors may have been endophytic in orchid ancestors. This also applies to the non-rhizoctonia fungi that were secondarily recruited by several orchid lineages as mycorrhizal partners. Indeed, from our review of the published literature, they are often detected, probably as endophytes, in extant rhizoctonia-associated orchids. Conclusion The orchid family offers one of the best documented examples of the ‘Waiting Room Hypothesis’: their mycorrhizal symbioses support the idea that extant mycorrhizal fungi have been recruited among endophytic fungi that colonized orchid ancestors.

Résumé :

A rescue program was made to save orchid plants in Selangit Village by initiating and involving the community. This activity began in 2017 and now, more than 250 species of orchid plants have been successfully rescued. The decline of some species of orchid plants are due to many factors, such as the endemic nature, forest fire, illegal logging, and illegal sales by collector can be an accelerator of their extinction. This activity can be a trigger to increase insight and ideas for the government and local community in developing natural areas. Working together between PT. Pertamina EP Pendopo Field and South Sumatera Natural Resources Conservation Center to build the Selangit Greenhouse aims to save orchid plants and can be an education facility for educators and learners. Next, this program advised to development of tourist village destinations by increasing training and promotion activities of flora tourism activities, and can be sustainable social activity in rescuing orchids and rare plants in Selangit village.

Résumé :

Orchidaceae is a diverse, globally important plant family with high conservation assessment and prioritization requirements. The checklist of Orchidaceae in Mongolia was updated based on herbarium materials, literature, and field observations. Mongolian orchids were revised as comprising 26 taxa belonging to 14 genera with major updates were conducted on Herminium and Epipactis. In particular, H. alaschanicum, previously noted in the Alashan Gobi region, was added to the flora of Mongolia based on literature and type specimens. Epipactis helleborine and E. palustris were excluded from the Mongolian flora owing to the absence of herbarium specimens and wild collection from Mongolia. Assessment of all orchid species at the national level resulted in 1, 4, 7, 11, and 2 species as critically endangered (CR), endangered (EN), vulnerable (VU), near threatened (NT), and data deficient (DD), respectively, according to IUCN criteria. Species richness and conservation gap analyses of 970 georeferenced orchid records based on 0.5° × 0.5° grid cells across 16 phytogeographical regions of Mongolia, showed that four phytogeographical regions, Khangai, Khuvgul, Khentii and Mongolian Dauria, have a high number of orchids. Regrettably, most orchid-rich locations in Mongolia are not fully within protected areas, highlighting the need for protection management updates. Based on herbarium collections, we prepared grid distribution maps of the 26 taxa using 40 × 40 km2 grids. Photographs of 18 taxa taken during fieldwork were included, providing valuable information on species morphology and typical habitat.

Résumé :

Myanmar is situated in Southeast Asia, where species richness and diversity are very high. Myanmar orchid flora is very rich, but still poorly known because botanical explorations have sharply decreased in Myanmar since 1950. The present study provides a checklist of Myanmar orchid flora which includes 1040 species and 151 genera currently known from Myanmar, based on the herbarium specimens, literature and online databases. The number of species is increased by approximately 200 species more than that given in the checklist of Kress et al. (2003), mainly due to recent discoveries of new species to science and new records for Myanmar. There are 76 endemic species of Orchidaceae in Myanmar. It is estimated that ca. 150–300 species still remain as unidentified and are expected to be discovered in further studies on Myanmar orchid flora.

Résumé :

This review summarises scientific knowledge concerning the mycorrhizal associations, pollination, demographics, genetics and evolution of Australian terrestrial orchids relevant to conservation. The orchid family is highly diverse in Western Australia (WA), with over 400 recognised taxa of which 76 are Declared Rare or Priority Flora. Major threats to rare orchids in WA include habitat loss, salinity, feral animals and drought. These threats require science-based recovery actions resulting from collaborations between universities, government agencies and community groups. Fungal identification by DNA-based methods in combination with compatibility testing by germination assays has revealed a complex picture of orchid–fungus diversity and specificity. The majority of rare and common WA orchids studied have highly specific mycorrhizal associations with fungi in the Rhizoctonia alliance, but some associate with a wider diversity of fungi. These fungi may be a key factor influencing the distribution of orchids and their presence can be tested by orchid seed bait bioassays. These bioassays show that mycorrhizal fungi are concentrated in coarse organic matter that may be depleted in some habitats (e.g. by frequent fire). Mycorrhizal fungi also allow efficient propagation of terrestrial orchids for reintroduction into natural habitats and for bioassays to test habitat quality. Four categories of WA orchids are defined by the following pollination strategies: (i) nectar-producing flowers with diverse pollinators, (ii) non-rewarding flowers that mimic other plants, (iii) winter-flowering orchids that attract fungus-feeding insects and (iv) sexually deceptive orchids with relatively specific pollinators. An exceptionally high proportion of WA orchids have specific insect pollinators. Bioassays testing orchid-pollinator specificity can define habitats and separate closely related species. Other research has revealed the chemical basis for insect attraction to orchids and the ecological consequences of deceptive pollination. Genetic studies have revealed that the structure of orchid populations is influenced by pollination, seed dispersal, reproductive isolation and hybridisation. Long-term demographic studies determine the viability of orchid populations, estimate rates of transition between seedling, flowering, non-flowering and dormant states and reveal factors, such as grazing and competition, that result in declining populations. It is difficult to define potential new habitats for rare orchids because of their specific relationships with fungi and insects. An understanding of all three dimensions of orchid habitat requirements can be provided by bioassays with seed baits for fungi, flowers for insects and transplanted seedlings for orchid demography. The majority of both rare and common WA orchids have highly specific associations with pollinating insects and mycorrhizal fungi, suggesting that evolution has favoured increasing specificity in these relationships in the ancient landscapes of WA.

Résumé :

Wetland ecosystems are important habitats for the growth and survival of numerous terrestrial orchids in Europe. This study reviews the current knowledge on the orchids of wetland vegetation in the Central Balkans. The orchid flora was analyzed from taxonomic, phytogeographical, ecological and conservation aspects. The most important taxa include the two Balkan endemics (Dactylorhiza cordigera subsp. bosniaca and D. kalopissi subsp. macedonica) and the three subendemics of the Balkans and the Carpathians (Dactylorhiza cordigera subsp. cordigera, D. maculata subsp. transsilvanica and Gymnadenia frivaldii), as well as a considerable number of Central European, Eurasian and boreal orchid representatives. Several orchid taxa occurring in the wet meadows and fens of the Central Balkans have a southern limit of their distribution in this part of Europe, suggesting that wetlands are important refuges for them. In total, 33 orchid taxa were recorded in plant communities from five classes, 10 orders and 17 alliances. Most orchid taxa grow in the following wetland vegetation types: wet meadows (class Molinio-Arrhenatheretea, order Molinietalia caeruleae, alliances Molinion caeruleae, Deschampsion cespitosae and Calthion palustris); fens (class Scheuchzerio palustris-Caricetea fuscae, order Caricetalia fuscae, alliance Caricion fuscae); tall-herb vegetation along mountain streams and springs (class Mulgedio-Aconitetea); marshes and herb-land vegetation of freshwater or brackish water bodies (class Phragmito-Magnocaricetea). This study highlights the importance of serpentine and silicate wetland vegetation types as important habitats for the survival of terrestrial orchids. In addition, detailed taxonomic, ecological and chorological studies of the wetland orchids of the Central Balkans need to be carried out in order to establish a successful plan for their conservation.

Résumé :

Liwa Botanical Garden is located in West Lampung Regency which has an area of 86.6 hectares and is one of the conservation of ornamental plants that presents the flora of the Bukit Barisan Selatan National Park. One of the flagship collections of this botanical garden is a native orchid. Disease infection is still a major obstacle in the cultivation and development of native orchid potential at Liwa Botanical Garden. Based on the results of previous studies, it is known that several individual natural orchid collections from Liwa Botanical Garden showed symptoms of fungal disease infections. Disease infections can inhibit plant growth and resistance and reduce the aesthetic value periodically. Symptoms of infection include necrotic patches on the upper surface of the leaf. This research was conducted to determine the identification of diseases and efforts to protect native orchids against fungal infections at Liwa Botanical Garden through a collection of samples that showed symptoms of infection, analysis of disease symptoms, and analysis of disease resistance levels. The results showed that the response of the native orchid at Liwa Botanical Garden to fungal infections was showed symptoms of wilting in the leaves, namely in the orchids Eria sp., Dendrobium sp., and Cymbidium sp. turns black on the edge of the leaf, Thrixspermum sp. The type of orchid most commonly infected with fungus is Cymbidium sp. a total of 8 samples, and Thrixspermum sp. 3 samples, Eria sp. as many as 4 samples, Dendrobium sp. and Calanthe triplicata as many as 6 samples. The type of native orchid that is most susceptible to fungal infections is Dendrobium sp. and Eria sp. with disease intensity of 74.11% and 22.3%. The results of this activity are expected to be basic information in efforts to protect plants against diseases to support the application of conservation of native orchids on Liwa Botanical Garden.

Résumé :

The composition of the orchid flora of Mt Mulanje, Malawi, is analysed. The altitudinal distribution of the orchids, the distribution of the terrestrial and epiphytic species and the extralimital distribution of the species is assessed for both genera and subfamilies (after the systematic concept of Dressier 1981). The altitudinal distribution of species endemic to Malawi is also assessed. The terrestrial species show a significant increase with altitude whereas the epiphytic species are more dominant al the lower levels. A similar increase is also found in the species endemic to Malawi. An analysis of the distributions shared with other African countries reveals that most species also occur in Zambia, Zimbabwe and East Africa, whereas significantly fewer species are shared with Angola, southern Africa, Mocambique, Zaire and West Africa. Most species shared with tropical African countries are found on the lower slopes of Mt Mulanje.

Résumé :

Abstract Currently, little information is available about the orchid flora in the “Iron Gates” Nature Park, especially due to the lack of the data regarding the detailed geographical distribution and the actual conservation status of species and populations. According to the data provided by the specialist literature for the south-west of Romania, 39 species of orchids are found in this area, of which 29 are in the Danube Gorge (known as Clisura Dunării ‒ “Iron Gates” Nature Park). The field researches regarding the Orchidaceae L. family in the “Iron Gates” Nature Park area have been conducted over a period covering 15 years, from 1996 to 2011. During research conducted in the field I acknowledged the presence of 23 orchid species in the Danube Gorge area and ascertained the presence of new orchid species in the research area: two new species in the Danube Gorge area (“Iron Gates” Nature Park): Epipactis purpurata Sm. and Listera ovata (L.)

The paper provides a short review of Bulbophyllum species recorded in Laos and Vietnam during the two last decades and continues the publication of results of our successive studies of the genus in this area. It presents data on two new species for science discovered in Laos (Bulbophyllum pachypodum) and Vietnam (B. neglectipetalum), one lesser known species for the flora of Laos (B. microtepalum), two new records for the flora of Vietnam (B. echinulus, B. setilabium), and new illustrated data on B. secundum insufficiently known in the flora of Vietnam. Bulbophyllum fascinator earlier accepted in specific rank reduced into the synonymy of B. putidum on the base of studies of newly obtained materials. Taking into consideration the new data presented in this paper, the flora of Laos presently includes 85, and flora of Vietnam 151 Bulbophyllum species, excluding Monomeria, Trias, and Sunipia. It is the largest genus in the orchid floras of both countries.

Two new orchid records are reported for Hidalgo, Notylia barkeri Lindl. and Trichocentrum cosymbephorum (C. Morren) R. Jiménez & Carnevali. The genus Notylia is reported for the first time, and the list of orchid flora is updated to include 110 taxa. Unexpectedly, the species were recorded in abandoned orange plantations rather than natural vegetation, likely because of the high anthropogenic pressure exerted on their natural populations. These new records highlight the importance of continuing to survey regions such as Hidalgo with scarce orchid records, including both natural and modified vegetation.

Résumé :

The Orchid species cenopopulations (Cypripedium calceolus, C. macranthon, C. guttatum, Neottianthe cucullata) growing in Krasnoyarsk suburban pine cenoses at the forest-steppe were studied. Orchid species are included in the Red Book of the Krasnoyarsk Territory. The investigation objectives are Orchid species occurrence studying and population’s age structure determining in the Krasnoyarsk suburban pine cenoses, both under recreational load and in control. The results of the four species occurrence dynamics at the period 2017-2021 in the control cenosis and cenoses under the anthropogenic influence are presented. In the studied period, the Neottianthe cucullata occurrence did not change, regardless of the level of recreational impact. This species blooms in August, when the recreant’s activity decreases, which can explain its numbers preservation at the same level. The Cypripedium occurrence dynamics depends on the degree of recreational impact. As a result of the ontogenetic analysis, the populations of Neottianthe cucullata, Cypripedium macranthon, and C. guttatum in the control sample area belong to the middle-aged normal complete populations. Populations of Neottianthe cucullata, Cypripedium macranthon, C. calceolus in suburban pine cenoses under the recreational impact should be classified as middle-aged normal incomplete.

Résumé :

Biological and ecological investigations of islands are crucial to explain ecosystem functioning. Many studies on island biodiversity are carried out on oceanic islands. In contrast, information on continental islands, such as those in the Mediterranean Sea, is very often fragmented in space and time. Here, a synopsis of the Orchidaceae of Sardinia is presented based on literature surveys and recent botanical field studies. Our final list comprises of 64 species and 14 genera: thirteen species and subspecies were recognized as endemic and four new species were recorded for the flora of the island: Anacamptis palustris (Jacq.) R.M. Bateman, Pridgeon & M.W. Chase; Himantoglossum hircinum (L.) Spreng; Orchis italica Poir.; and Platanthera kuenkelei subsp. kuenkelei var. sardoa R.Lorenz, Akhalk., H.Baumann, Cortis, Cogoni & Scrugli. This orchid richness reflects the geological history of the island that was linked to the mainland several times, facing long periods of isolation. We also discuss a critical point-of-view of the biodiversity shortfalls still problematic for insular orchids. Indeed, within the Mediterranean Basin, the greatest amount of endemism occurs mainly on large islands, and, despite a long history of botanical exploration in European countries, many of them are scarcely investigated. This annotated synopsis shows the potential of continental islands to understand trends in ecology and evolution. Further studies are required to complete our knowledge of the orchid diversity on continental islands in order to propose scientific-based conservation programs to preserve these unique taxa.
