Abstract

A new species, Thrixspermum odoratum X.Q. Song, Q.W. Meng & Y.B. Luo from Hainan Island, south China, is described and illustrated. It belongs in sect. Thrixspermum and is closely related to T. tsii, but differs by having dense and distichous bracts, an irregularly-shaped clump or an erect lamellum at the base of lip, longer midlobe of lip, and fragrant flowers. A key to the five species of sect. Thrixspermum in China is presented. Thrixspermum odoratum is a host-specific epiphyte, being found only on one tree species.
