Trachoma Garay, originally described from northern India,was recently collected from Motuo, Tibet Autonomous Region, China. The flowers are similar to those of Tuberolabium Yamamoto, but in that genus the flowers open simultaneously along an elongate rachis and with deeply cleft separated by a hyaline flange poliionia, whereas in Trachoma they open in successive clusters on an abbreviated rachis and with entire or obscurely sulcate pollinia.

Key words: Trachoma, T. coarctatum, China, newly recorded genus, Orchidaceae
