Suddee, S. & H. Æ. Pedersen. 2011. A new species of Lecanorchis (Orchidaceae) from Thailand. Taiwania, 56(1): 37-41.

Abstract. Lecanorchis betongensis, a new species from tropical rain forest in southern peninsular Thailand, is described and illustrated. The combination of semicircular column wings and a labellum with an odd number of major veins (but devoid of calli) places the new species in sect. Lecanorchis. However, the lack of any fusion between the labellum and the column readily distinguishes L. betongensis from all other species of the genus. The new species seems morphologically closest to L. malaccensis from Thailand, Malaysia and Sumatra.

Keywords: Flora of Thailand, Lecanorchis betongensis, orchids, systematics, taxonomy, Vanilloideae.
