Description
Orchids in the genus Pholidota are sympodial epiphytic, lithophytic or, rarely, terrestrial herbs with pseudobulbs, each with one or two large, stalked leathery leaves. A large number of small flowers are arranged in two ranks along a thin, wiry flowering stem that emerges from the top of the pseudobulb. There is a large, papery bract at the base of each flower. The flowers are white, cream-coloured, yellowish or pinkish with a concave dorsal sepal and smaller petals. The labellum is rigidly fixed to the base of the column and there is a deep sac-like structure at its base.

Taxonomy and naming
The genus Pholidota was first formally described in 1825 by John Lindley who published the description in Hooker's Exotic Flora, Containing Figures and Descriptions of New, Rare or Otherwise Interesting Exotic Plants. The name Pholidota is derived from the Ancient Greek word pholidotos meaning "clad in scales", referring to the large bracts at the base of the flower in some species.
