Szlachetko, D. L. 2003: Genera et species Orchidalium. 7. Vandeae. — Ann. Bot. Fennici 40: 67–70.

The following genera of the tribe Vandeae (, Vandoideae) are described as new to science: Barombiella Szlach., Blumeorchis Szlach., Lacroixia Szlach., Neocribbia Szlach., and Ormerodia Szlach. New combinations proposed in Vandeae are Coenadenium (Summerh.) Szlach., stat. & comb. nov. and Lindl. sect. (Garay) Szlach., stat. & comb. nova. Twenty-six new combinations at the species level are validated.

Key words: nomenclature, Orchidaceae, taxonomy, Vandeae, Vandoideae
