Small epiphytic or lithophytic herb, the lightgreen pseudobulbs forming a chain. Flowers white with a more or less distinct pink stripe along the centre of the sepals and a broad yellow central line on the recurved lip.
Notes: This is essentially a South African species, which is known only from a single record from the Chinhoyi area in northern Zimbabwe. As the specimen flowered in cultivation in California, there is doubt about the correctness of the given locality. No other specimens of this species have been found in the Chinhoyi area or elsewhere in Zimbabwe, since then.
