TL;DR: The paper continues publication of new original data on orchid diversity in Vietnam (tribes Cymbidieae and Vandeae) obtained in 2016-2018 and includes data on 2 genera and 10 species new for the flora of Vietnam.
Abstract: The paper continues publication of new original data on orchid diversity in Vietnam (tribes Cymbidieae and Vandeae) obtained in 2016-2018. It includes data on 2 genera and 10 species new for the flora of Vietnam. Among them, six species are new to science (Ascocentrum hienii, Biermannia canhii, Cymbidium tamphianum, Gastrochilus setosus, Malleola luongii, Robiquetia orlovii). Four other species are found on the territory of Vietnam for the first time (Bogoria raciborskii, Lesliea mirabilis, Pennilabium struthio, Uncifera obtusifolia). Two genera, Bogoria and Lesliea, are newly recorded for the flora of Vietnam. One new nomenclature combination (Ascocentropsis malipoensis), one new name (Ascocentropsis yunnanensis) and one lectotype (for Uncifera obtusifolia) are proposed. When the new data presented in this paper are included, the known orchid flora of Vietnam comprises about 1220 documented species from 174 genera.
TL;DR: One more new species that differs strikingly from all hitherto known species of Biermannia King & Pantling was recently discovered in southern Vietnam.
Abstract: Biermannia King & Pantling (1898a: 591) comprises about ten species distributed from northeastern India and southern China through the Indochinese and Malay Peninsulas to Sumatra, Java and Borneo (Comber 1990, 2001, Seidenfaden & Wood 1992, Pearce & Cribb 2002, Chen & Wood 2009, Chase et al. 2015). All species of this genus are miniature, canopy epiphytes with small, unattractive fugacious flowers lasting only few hours in the morning. As a result, representatives of this genus are easily overlooked in botanical surveys, poorly represented in herbaria and remain infrequently inventoried in local floras throughout its range. One more new species that differs strikingly from all hitherto known species of this genus was recently discovered in southern Vietnam. Here we describe and illustrate this unusual plant.
TL;DR: Biermannia jainiana is an endemic orchid of Arunachal Pradesh reported from Sessa, West Kameng District in 2001, and the conservation status of the species has been assessed.
Abstract: Biermannia jainiana is an endemic orchid of Arunachal Pradesh reported from Sessa, West Kameng District in 2001. This is the second record of this species from the same locality. Hence the conservation status of the species has been assessed.
Abstract: Two genera, Biermannia King Pantl. and Cleisostomopsis Seidenf., together with four species, Biermannia calcarata Averyanov, Cleisostomopsis eberhardtii (Finet) Seidenf. Smitinand, Liparis perpusilla Hook. f., and Schoenorchis fragrans (Par. Rchb. f.) Seidenf., are reported as new records to China.
