Photo by Robert & Kerry Dressler

Common Name The Triangular Seed Pod Vanilla

Flower Size 3" [7.5 cm]

Found in Costa Rica, Panama, Colombia and northern Brazil at elevations of 120 to 350 meters as a large sized, hot growing viney epiphyte with a thin stem carrying elliptic, strongly acuminate, gradually narrowing below in to the petiolate base leaves that blooms at least in the summer on a successively to several flowered inflorescence with lanceolate, much shorter than the pvary bracts.

"A very distinct Vanilla known from wet forests in Central America, Colombia, and from the delta of the Amazon River. The main difference between V. trigonocarpa and V. pauciflora is the more trilobed lip of V. trigonocarpa. The plant seems to be related to V. espondae from Colombia, and perhaps to V. sprucei."
