Orchidaceous Additions to the Flora of Burma (Myanmar)

Abstract

This paper, based on literature and herbarium studies, deals with three genera viz. Acrochaene, Aorchis and Cryptochilus and 26 species viz.: Acrochaene punctata Lindl., Anoectochilus lylei Rolfe ex Downie, Aorchis spathulata (Lindl.) Vermeulen, Bletilla elegantula (Kranzlin) Garay & Romero, Calanthe brevicornu Lindl., C. densiflora Lindl., C. mannii Hook. f., C. sylvatica (Thouars) Lindl., C. triplicata (Willem.) Ames, C. trulliformis King & Pantl., Cheirostylis spathulata J. J. Sm., C. yunnanensis Rolfe, Cryptochilus lutea Lindl., C. sanguinea Wallich, Cymbidium devonianum Lindl. & Paxton, Dendrobium hancockii Rolfe, Epigeneium rotundatum (Lindl.) Summerh., Epipogium aphyllum Sw, Eria stricta Lindl., Eulophia sooi W. Y. Chun & T. Tang ex S. C. Chen, Geodorum pulchellum Ridl., G. siamense Rolfe ex Downie, Goodyera schlechtendaliana Reichb. f., Hemipilia cordifolia Lind|., Hetaeria finlaysoniana Seidenf. and Luisia magniflora Tsi & S.C. Chen as new records for Burma. Type study enabled us to reduce six species (Calanthe burmannica Rolfe, Dendrobium moulmeinense Parish ex Hook. f., D. hexadesmia Reichb. f., D. tapingense W. W. Sm., Diplomeris boxallii Rolfe ex Kranzlin and Orchis subrotunda King & Pantl.) to synonymy (of Calanthe ceciliae Reichb. f., Dendrobium devonianum Paxton, D. parcum Reichb. f., Diplomeris pulchella D. Don and Hemipilia calophylla Par. & Reichb. f. respectively) and exclude five species (Aerides flabellata Rolfe ex Downie, Cypripedium elgans Reichb.f., Geodorum densiflorum (Lam.)Schltr., G. recurvum (Roxb.)Alston and Peristylus coeloceras Finet) from the flora.
