Herbarium material collected in 2013–2015 in Cambodia and Laos provides 298 new localities for 167 orchid species (from 57 genera). Almost all reported locations are new on the territory of studied countries. These data provide substantial basis for understanding of present day distribution of rare species needed protection.Among reported species, 8 species are new for the flora of Cambodia (Bulbophyllum macranthum, B. orientale, B. physocoryphum, B. retusiusculum, Dendrobium pachyphyllum, Eria tenuiflora, Pholidota recurva, Thelasis pygmaea) and 43 species are new for the flora of Laos (Bulbophyllum ambrosia, B. andersonii, B. bicolor, B. bisetoides, B. delitescens, B. depressum, B. forrestii, B. lilacinum, B. longibrachiatum, B. psyhoon, Calanthe alismifolia, C. sylvatica, Cheirostylis pusilla, Cleisostoma melanorachis, C. subulatum, C. williamsonii, Coelogyne eberhardtii, C. leucantha,C. ovalis, Dendrobium eriiflorum, D. falconeri, D. trantuanii, D. williamsonii, Didymoplexis pallens, Epigeneium fuscescens, Eria apertiflora, E. bambusifolia, E. pachyphylla, Flickingeria fimbriata, Gastrochilus suavis, Liparis mannii, L. sootenzanensis, Luisia ramosii, Oberonia kwangsiensis, O. maxima, Pelatantheria insectifera, Phalaenopsis braceana, Pholidota yunnanensis, Schoenorchis scolopendria, S. tixieri, Tainia cordifolia, Thrixspermum calceolum). Five species (Dendrobium minusculum, Oberonia simplex, Porpax capuccinorum, P. laosensis and Taeniophyllum filiferum) discovered in Cambodia in Laos are described as new for science. One genus (Didymoplexis) was found in Laos at first. Such rare ornamental species as Aerides falcata, A. flabellata, A. rosea, Arundina caespitosa, Ascolabium pusillum, Bulbophyllum bicolor, Calanthe cardioglossa, Coelogyne assamica, C. calcicola, C. eberhardtii, C. flaccida, C. trinervis, Dendrobium aphyllum, D. christyanum, D. chryseum, D. chrysotoxum, D. crepidatum, D. dixanthum, D. falconeri, D. fimbriatum, D. findleyanum, D. gratiosissimum, D. jenkinsii, D. loddigesii, D. nobile, D. senile, D. thyrsiflorum, D. trantuanii, D. trigonopus, D. williamsonii, Doritis pulcherrima, Gastrochilus suavis, Holcoglossum kimballianum, H. subulifolium, Hygrochilus parishii, Paphiopedilum concolor, P. dianthum, Phalaenopsis braceana, Schoenorchis scolopendria, S. tixieri, Spathoglottis affinis, Tainia cordifolia, Vanda brunnea, V. denisoniana, V. flavobrunnea become presently very rare on the territory of studied local floras and badly need protection to prevent their extinction in nature.
