The original discoverers of this plant appear to be Ruiz and 
Pavon, from whom we possess specimens. It has been frequently 
gathered in Southern Mexico near Oaxaca, Talea, Zacuapan, 
Vera Cruz, Colipa, Mirador, as specimens from Leibold! Ehren- 
berg! Liebmann! Linden! Galeotti! Jiirgensen! Schiede! Ghies-

tenango; Bernoulli! Turialba in Costa Rica, 27.38. 1857; 
Wendland! Surinam, woods between the Saramaca and Copi- 
nami; Kegel! A plant much resembling that species is Hipiden- 
drum Ottonis, Rchb. f. It grows near Caraccas and in Trinidad, 
also in Cuba, and is easily distinguished by its smooth ovaries, 
crestless anthers (often three instead of one) and smaller flowers. 
Rhizome creeping, thickish, sheathed, with single roots. Pseu- 
dobulbs varying from pyriform to ligulate, ancipitous, furrowed 
when old, with a few acute scariose nervous pallid ochre-coloured 
sheaths, often covered with many obscure small spots. Leaf
