This species was recorded in FRPS on the basis of two collections that were assigned with hesitation. The record here is based on a collection from Yunnan, Henry 12273, which agrees with the type collection, Wallich 2621, as seen on microfiche. Three varieties described by Bitter from India were recorded in FRPS, but it was said that the Chinese material was not a good match for any of them, and we have not seen authenticated material.
