Elleanthus ensatus (Lindl.) Rchb. f., Annales Botanices Systematicae 6: 482. 1861.

Evelyna ensata Basionym: Evelyna ensata Lindl., Orchidaceae Lindenianae 11-12. no. 64. 1846. Type: Venezuela, Merida, "Sierra Nevada, at the height of 8000 feet [2438 m], August", Linden 664; Lectotype (designated here): P (P00389702); isolectotypes: W (W-R51384), W (W-R51392), W-R-drawing (W-R30233).

Note.

In the protologue of Evelyna ensata Lind., the author indicates in a short note the gathering of Linden 664 as the type. We found that this collection actually consists of three specimens deposited in two institutions: the Naturhistorisches Museum in Vienna and the Muséum National d’Histoire Naturelle in Paris. The Vienna specimens have no annotation on their status, but they have a designation of the collection number Linden 664; the specimen stored in P is labelled as the type. We have analysed and compared all of them with the diagnosis. We analysed not only vegetative features, but also we compared the floral structures. These specimens have all the features of Evelyna ensata and one of them was selected as the lectotype (Fig. 4 ).

There is a Reichenbach drawing kept at W (W-R30233), labelled E. ensata and numbered 644. In the protologue, Lindley (1846: 12) indicates a gathering Linden 664. However, drawing deposits in Vienna Herbarium definitely correspond with Lindley’s species. Therefore, we can assumed that this is probably an error.
