Chromosome number, heterochromatin, and genome size support recent polyploid origin of the Epidendrum nocturnum group and reveal a new species (Laeliinae, Orchidaceae).
The Epidendrum nocturnum Jacq. group comprises about 60 species. Nine species occur in Brazil, predominantly in the Atlantic and Amazon Forests. The group is taxonomically complex because its species are morphologically similar and not easily distinguished. The main objective of this work is to characterize their chromosome evolution and how... -

Systematics and conservation of British and Irish orchids: a "state of the union" assessment to accompany Atlas 2020.
Prompted by concurrent completion of the latest plant atlas for Britain and Ireland, the orchid flora of these islands is reviewed in detail, focusing on 21st century progress in both systematics research and formal conservation categorisation under IUCN criteria. DNA-based phylogenies consistently circumscribe monophyletic groups that constitute obvious genera, though... -

Floral mimicry in Oncidioid orchids.
Extensive radiation in oncidioid orchids (subtribe Oncidiinae) has resulted in over 1,700 species in tropical America in some 70 genera. They exhibit a wide range of habitats, occurring terrestrially or, more commonly, epiphytically and can be found from sea level to the Andean paramós and from deserts to rainforests.Tropical America, Floral mimicry, Orchidaceae, and Oncidioid orchids
