Common Name The Extended Cyrtochilum
Flower Size 2" [5 cm]
Found in Colombia, Ecuador and Peru at elevations around 1200? [1600] to 2900 meters as a medium sized, cool to cold growing epiphyte or terrestrial with closely spaced clump-forming growths consisting of egg to pear shaped, compressed, ancipitous pseudobulbs enveloped by 2 to more pairs of conduplicate, leafless and leaf bearing sheaths and carrying a single, apical, arching, linear, acute, gradually long-narrowed below into the conduplicate, petiolate base leaf that blooms in the winter and spring on an axillary, from the base through a leaf sheath, slender, twining, much longer than the leaves, mostly pendulous, to 24" [to 60 cm] long, paniculate, many short, distichous, 2.4 to 3.1" [6 to 8 cm] between each branch, each branch to 5" [12.5 cm] long, 5 to 7 flowered each branch, many flowered inflorescence arising on a newly matured pseudobulb with several very close bracts and carrying decidedly unpleasant smelling flowers.
This species, C murinum, C diodon and C umbonatum are all very similar and may all be in one variable species complex but I have kept them separate for now.
