Cyrtopodium album Barbosa Rodrigues 1891

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.Published as part of Thiago E.
