Common Name The Cerro Del Torra' Pleurothallis

Flower Size .4" [1 cm]

Found in Choco' department of Colombia at elevations around 1900 to 2000 meters as a medium sized, cool to cold growing terrestrial with erect, slender, prolific ramicauls with a tubular sheath below the middle and 2 to 3 others at the base and carrying a single, apical, erect, coriaceous, ovate, slightly acuminate, acute, cordate below into the sessile base leaf that blooms in the later summer through early winter on an arching, pendent,to .2 to 3.2" [ 8 cm] long including the .8 to 1.2" [2 to 3 cm] long peduncle, loosely few flowered inflorescence arising through a spathe at the base of the leaf and carrying non-resupinate flowers.

" Pleurothallis caucensis differs from P. torrana in the length of the ramicauls, raceme, sepals and petals, all of which are longer in P. caucensis than in P. torrana in the lip shape which is suborbicular in P. caucensis and rhombiform in P. torrana; and in the lip callus, which consists of a pair of lunate calli in P. caucensis and a single transverse callus in P. torranaPleurothallis caucensis can be distinguished from P. bicornis by the petals, which in P. caucensis are free, projected laterally and downward and in P. bicornis are adpressed and project forwards; by the lip which is completely fimbriated in P. caucensis and only fimbriated on the margin of the central lobe in P. bicornis; and by the lateral lobes of the lip which are flattened and surpass the column in P. caucensis and which are auriculate, not surpassing the column in P. bicornis. Pleurothallis caucensis differs from P. subreniformis in the length of the raceme, sepals and petals, which are longer in P. caucensis than in P. subreniformis; and in the lip shape, which is suborbicular in P. caucensis and hippocrepiform with an acute apex on the midlobe in P. subreniformis. ."
