TRACHOMA View in CoL

Trachoma Garay (1972: 207) . Type species: Trachoma rhopalorhachis (Rchb.f.) Garay.

Trachoma ( Fig. 1K View FIGURE 1 ) is characterised by abbreviated, swollen inflorescenes that carry successive clusters of one to a few ephemeral flowers. A column foot is lacking. Flowers of Trachoma are superficially similar to those of Tuberolabium , and the two genera have been confused, although Tuberolabium differs in several respects. Tuberolabium has elongated, pendent inflorescences; flowers last up to several weeks, and individual flowers mostly possess a prominent column foot. Based on these slight differences Wood (1990) united Tuberolabium with Trachoma but placed those Tuberolabium species with a column foot in Parapteroceras Aver. in Averyanov & Huyen (1990: 723). Molecular systematic studies show a clear distinction between Trachoma and Tuberolabium . We therefore accept Trachoma and consider Parapteroceras to be a synonym of Tuberolabium .
