petalisque pateniibus lanceolatis subsequalibus acutis, labelli 

 trilobi laciniis lateralibus lineari-oblongis obtnsis intermedia 

 unguiculata obovati apice inflexo acuto : callo elevato 

 acuminato secus medium canaliculate columns sub apice / 

 auriculata- — A fine species closely allied to E. flavum. It 

 has a panicle regularly branched up to the apex, nearly a 

 foot and a half long, with each side-branch having from 2 — 4 

 flowers. According to M. Schomburgk, the sepals and 

 petals are green dotted with purple, the labellum white with 

 a purple stain at its base, the flowers aromatic, the stem six 

 feet high. I have only seen portions of the panicle — Among 

 the granitic ridges of the R. Corentyn ; also in similar places 

 near the Cayuni and Guiana, among boidders where a little 

 soil has collected, Schomburgk, n. 195. (herb, propr.)
