AbstractIn this paper we report various findings from our ongoing studies of Crepidium (Orchidaceae), mainly conducted in preparation of the Flora of Thailand account on the genus: (1) the new combinations C. chamaeorchis (Schltr.) Nuammee, Seelanan, Suddee & H.A. Pedersen and C. szemaoense (Tang & F.T. Wang) Nuammee, Seelanan, Suddee & H.A. Pedersen are made and substantiated; (2) a putative natural hybrid between C. acuminatum (D. Don) Szlach. and C. polyodon (Hook.f.) Szlach. is discussed and highlighted as being the first convincing case of natural hybridization reported for Crepidium; (3) C. bahanense (Hand.-Mazz.) S.C. Chen & J.J. Wood, C. josephianum (Rchb.f.) Marg., C. maximowiczianum (King & Pantl.) Szlach. and C. micranthum (Hook.f.) Szlach. are reported as new national records for Thailand; (4) the name C. josephianum (Rchb.f.) Marg. is lectotypified. All taxa treated in this paper are documented by photos of live plants from their natural habitat in Thailand, and for each newly recorded species we provide a morphological description based on Thai material.
