LATE

Common Name The Large Flowered Catasetum

Flower Size 4" [10 cm]

Found in Venezuela and Peru? at elevations of 1100 to 2100 meters as a cool growing epiphyte with fusiform, slightly compressed pseudobulbs carrying up to 10 dark green, plicate, elliptic-lanceolate, leaves that blooms in the late spring on a basal, 14" [35 cm] long, ascending and then pendant, racemose, several [8] flowered inflorescence arising on a partially developed pseudobulb.

Once thought to be a variety of Catasetum pileatum but has now been given species status, it could possibly be a natural hybrid between C pileatum and C macrocarpum but it has not been reproduced artificially as yet.

Kew at this time puts this species as a synonym of C pileatum but I have left it separate at this time.
