Exploring the Orchid Flora of Montenegro: Ten Newly Identified Taxa

Diversity, Journal Year: 2025, Volume and Issue: 17(5), P. 337 - 337

Published: May 6, 2025

Montenegro, with approximately 3600 vascular plant taxa, represents one of the floristic diversity centers Balkan Peninsula and Mediterranean region. According to our current knowledge, about 80 100 orchids, including species, subspecies, hybrids, occur in this country. To refine understanding orchid extensive fieldwork herbarium revisions were conducted. As a result, ten new taxa recorded Montenegro for first time. These include Epipactis helleborine subsp. distans, E. leptochila neglecta, Gymnadenia densiflora, Neotinea ustulata var. aestivalis, Ophrys archipelagi, O. grammica, Pseudorchis albida tricuspis. In addition, intergeneric hybrid, ×Serapicamptis rousii, two intrageneric, Anacamptis ×nicodemi A. ×olida, found. Distribution data, ecological preferences, population sizes newly registered have been given. This study underscores great potential flora discoveries world.

Systematics and conservation of British and Irish orchids: a "state of the union" assessment to accompany Atlas 2020

Kew Bulletin, Journal Year: 2022, Volume and Issue: 77(2), P. 355 - 402

Summary Prompted by concurrent completion of the latest plant atlas for Britain and Ireland, orchid flora these islands is reviewed in detail, focusing on 21st century progress both systematics research formal conservation categorisation under IUCN criteria. DNA-based phylogenies consistently circumscribe monophyletic groups that constitute obvious genera, though relationships among those genera remain less certain resistance to phylogenetic classification persists. Comparison species circumscription studies critical such as Dactylorhiza , Gymnadenia Platanthera Epipactis Orchis shows most recent has been achieved using techniques, which have also greatly increased understanding associated mycorrhizae. Most morphological disappointingly traditional, squandering opportunities morphometric identify discontinuities between species, allow comparison rates molecular evolution, underpin accurate quantitative descriptions designed aid identification. Possibly only one 53 recognised native still viewed endemic. Conventional views significance pollinator specificity seed output preferred measure fitness are questioned, mycorrhizae explored possibly under-rated ecological filters. distributions successive Atlases suggests diverse patterns change reflect a combination habitat modification, climate and, few cases, improved identification skills. Ecologically tolerant lowland Ophrys apifera praetermissa migrating northward rapidly, while genus Serapias appears be mounting cross-Channel invasion. Red-Listing categorisations, underlying criteria, supported decisions made within British Isles, but unfortunately, they translated poorly into equivalent European Global lists. Within Britain, Data Deficient category employed too frequently illogically; ironically, it sometimes used penalise having subjects serious research. Far from being "complete", present consensus view taxonomy evolution glacially impoverished Irish judged parochial complacent. Reinvigorated UK-based programmes integrate natives context urgently needed.

Advances in the Study of Orchidinae Subtribe (Orchidaceae) Species with 40,42-Chromosomes in the Mediterranean Region

Diversity, Journal Year: 2024, Volume and Issue: 16(1), P. 41 - 41

Published: Jan. 9, 2024

This study presents an updated analysis of cytogenetic data for several species within the 40,42-chromosome genera subtribe Orchidinae. The research includes insights into distribution heterochromatin obtained using C-banding and fluorochrome techniques. Our investigation confirmed variation in repetitive DNA sequences among pertaining to Neotinea s.l. Orchis s.str. These variations also potentially contribute diversification these species. Cytogenetic analyses group demonstrated that both H33258 DAPI staining result blocks fluorescent regions on numerous chromosomes. Particular attention was paid cytological composition polyploid commutata, focusing its potential origin. Based karyological results acquired, a hypothesis concerning origin N. commutata is proposed. most noteworthy revelations regard O. mascula complex. In species, telomeric areas all chromosome sets display extensive heterochromatin. Fluorochrome revealed many chromosomes were not seen with Giemsa staining. highlighted distinct feature mascula, where particularly large C-bands surrounding centromeric multiple found. However, provincialis, pauciflora, patens, C+ chromatin may show significant response Hoechst or DAPI+ unique cytomorphological arrangement observed unlike other members complex, suggest epigenetic phenomena. Additional are presented Dactylorhiza Gymnadenia. A deeper understanding diversity chromosomal structures orchids promises shed light mechanisms underlying speciation, adaptation, remarkable characteristic Orchidaceae family.
