Common Name The Black Purple Stanhopea

Flower Size to 7" [18 cm]

A medium sized, warm to cool growing epiphyte occuring on the easterrn slopes of the Mexican plateau at elevations of 1200 to 2000 meters with ovate, strongly ribbed and furrowed with age pseudobulbs carrying a single, apical, erect, coriaceous, plicate, lanceolate, acute, gradually narrowing below into the petiolate base leaf that blooms on a pendant, to 8" [to 20 cm] long, one to two flowered inflorescence subtended by large, chartaceous bracts and carrying 2 to 3 heavily fragrant [vanilla] flowers occuring in the summer and fall.

Many authorities put this one as a variety of S tigrina, I keep it separate only because they are found in cultivation named such much more often.
