Common Name The Many Hump-Like Swelling Peduncle Scaphosepalum

Flower Size 2" [5 cm]

Found in Antioquia department of Colombia at elevations of 1600 to 2000 meters as a small to just medium in size, cool growing epiphyte with erect, stout ramicauls enveloped by 2 to 3 short, loose, tubular sheaths carrying a single, apical, erect, coriaceous, elliptical, acute leaf that is gradually narrowed below to the slender channeled petiole that blooms in the fall and spring on an erect, loose, 20" [50 cm] long, flexuous, successively many flowered, racemose inflorescence with narrow, conduplicate, acute floral bracts.

"The purplish peduncle is slender and very rough, covered by a multitude of hard warts. The sepaline cushions, minutely pubescent and usually diffusely dotted with red-purple, are narrowly falcate and diverging with slender, straight, white tails. The middle sepal is attenuated into a long tail which is slightly bent between the middle and distal third and there is an obtuse angle on the inner surface between concave basal portions and the base of the tail." Luer 1988
