Abstract

This paper continues the publication of new data obtained during field studies in remote and poorly studied regions of Laos in 2015–2018. It provides descriptions of two new species (Bulbophyllum brachyscapum Aver. and Sunipia saccata Aver.), emended descriptions of two previously published but insufficiently known species (Cleisostoma verrucosum Aver., Oberonia vesiculifera Aver.) and reports of eight species newly recorded in the flora of Laos (Biermannia calcarata Aver., Bulbophyllum farreri (W. W. Sm.) Seidenf., Didymoplexiella trichechus (J. J. Sm.) Garay, Eria eriopsidobulbon C. S. P. Parish et Rchb. fil., Habenaria ciliolaris Kraenzl., Liparis caudata Aver. et K. S. Nguyen, Odontochilus umbrosus (Aver.) Ormerod, and Porpax ustulata (C. S. P. Parish et Rchb. fil.) Rolfe). Appropriate citations of regional literature, colour illustrations, data on types and distribution, descriptions, etymology, as well as notes on taxonomy and related species are provided for the studied species.
