Common Name The Paragua River Catasetum [Venezuelan River]
Flower Size 1.6" [4 cm]
Found in Venezuela and Brazil growing on trees along river banks and in wet forests at elevations of 50 to 1800 meters as a small sized, hot to cool growing epiphyte with fusiform pseudobulbs carrying, dark green, oblanceolate, plicate leaves and blooms in the spring and summer with a basal, slightly arching then pendant, 6" [15 cm] long, 2 to 8 flowered inflorescence arising on a newly emerging pseudobulb carrying resupinate flowers.
"Similar to C callosum but differs in the subcordate lip and truncated basal callus and it differs from Catasetum poriferum Lindl. 1838 by having long, fully developed antennae and a labellum with erect, patent lateral lobes. It is further distinguished by flowering almost invariably from the developing leaf shoot." Romero and Carnevalli 1989
