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 I am not sure of this determination as it does not conform to Dunsterville's drawing and I do not have any other decent reference. 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.
