Annotation

The herbarium material collected in 2012–2017 in Cambodia and Laos provides data on 281 new localities of 110 orchid species from 48 genera for Laos, and 4 new localities of 4 species from 4 genera for Cambodia. Among them, 3 species present new records for the flora of Cambodia (Eria ochracea Rolfe, Luisia macrotisRchb. fil., Trichoglottis seidenfadenii Aver.); 1 genus (Abdominea J. J. Sm.), and 13 species are new to the flora of Laos (Abdominea minimiflora (Hook. fil.) J. J. Sm., Bulbophyllum nanopetalum Seidenf., Chiloschista parishii Seidenf., Cleisostoma tricornutum Aver., Didymoplexis vietnamica Ormerod, Gastrochilus hainanensis Z. H. Tsi, Hetaeria alata Ridl., Malleola seidenfadenii Christenson, Phaius takeoi (Hayata) H. J. Su, Sarcoglyphis yunnanensis Z. H. Tsi, Schoenorchis fragrans (E. C. Parish et Rchb. fil.) Seidenf. et Smitinand, Thrixspermum fragrans Ridl., T. hystrix (Blume) Rchb. fil.). One new species is described, Bulbophyllum pseudorufinum Aver. The reported data provide a substantial basis for the understanding of the present-day distribution of rare species in Eastern Indochina.
