Trachoma, commonly known as spectral orchids,[2] is a genus of flowering plants in the family Orchidaceae.

Orchids in this genus are epiphytic plants with leafy stems, crowded, leathery leaves arranged in two ranks and a large number of relatively small, short-lived flowers that often open in successive clusters.

Orchids in the genus Trachoma are evergreen, epiphytic, monopodial herbs with long branching roots mostly adhering to the trees on which they grow.

[2][3][4] The genus Trachoma was first formally described in 1972 by Leslie Andrew Garay in Botanical Museum Leaflets, Harvard University.

"[5] Within the family Orchidaceae, the genus is classified in the subfamily Epidendroideae, tribe Vandeae, and subtribe Aeridinae.
