Common Name The Unequal Sepals Physosiphon

Flower Size .1" [3mm]

Found in Venezuela, Colombia, Ecuador and Peru in dwarf, mossy forests at elevations around 3000 meters as a mini-miniature sized, cold growing epiphyte with an short, erect ramicaul enveloped basally by 2 to 3 tubular sheaths and carrying a single, apical, coriaceous, minutely and fleshily mucronate apically, elliptic, narrowing below into the petiolate base leaf that blooms on an erect to arching, 1.6" [4 cm] long, few to several flowered, racemose, filiform inflorescence with all the flowers facing to one side of the rachis and held well above the leaves.

CAUTION Not sure of this determination as it does not conform to Dunsterville's drawing and I do not have any other decent ref3erence. Dunsterville's drawing is not representative of a flower from this genus so as to what it or this species may be is still suspect to me.
