Eulophia splendida (Koop. & P.J.Cribb) M.W.Chase & Schuit., Phytotaxa 491: 53 (2021).
Homotypic Names:

Oeceoclades splendida Koop. & P.J.Cribb, Orchid Digest 80: 41 (2019).
Description:
The species is very similar to Oeceoclades humbertii, but Oeceoclades humbertii has smaller flowers and four lanceolate leaves on the terminal pseudobulb and therefore is probably deciduous, where as Oeceoclades splendida has mostly only one (sometimes two) oval, flat leaves which persist for a number of seasons; this plant shows only one leaf per pseudobulb and the leaves fit the description and photos almost exactly; size of the flower segments are in range for Oeceoclades splendida; midlobe, if flattened, is a match to the line drawing in the original description.
Habitat:
Distribution:

Madagascar
