1. Cyrtopodium album Barbosa Rodrigues (1891: 127) , nom. dub.

Type: — unknown

The only original material available for this species is a description included in a key to Cyrtopodium Brown in Aiton (1813: 216): “ [Sectio] Microbulbosae; β foliis solitariis v. geminis coriaceis nervatis ”. Apparently, Cogniaux (1898a) was the first to synonymize C. album under C. eburneum , basionym of Koellensteinia here. Cogniaux’s concept appears to be followed without a deeper critical analysis by other botanists, e.g. Hoehne (1945), Foldats (1970), Pabst & Dungs (1977), Sprunger et al. (1996) and Romero-González et al. (2008). The description is insufficient to characterize the name as either a good name for a species or as a synonym, and so it is here classified as a doubtful name. It could be better understood if additional original material was one day found, which is unlikely due to the turbulent history of Barbosa Rodrigues’ original material.
