Common Name The Scabrous Pleurothallis [refers to the serrulate margins of the petals]

Flower Size .4" [1 cm]

Found in Morona-Santiago and Loja provinces of Ecuador, Amazonas department of Peru and La Paz department of Bolivia at elevations around 1600 to 2600 meters as a small to just medium sized, cool to cold growing, caespitose epiphyte with stout, erect ramicauls enveloped by a close tubular sheath below the middle and 2 to 3 others at the base and carrying a single, apical, erect, coriaceous, elliptical, subacute to obtuse, cuneate below into the ill defined, petiolate base leaf that blooms in the summer and fall on an erect to arching, arising through a narrow spathe, secund, loose, 8 to 12" [20 to 30 cm] long including the 4" [10 cm] long peduncle, simultaneously several to many flowered inflorescence with a tubular, oblique, shorter than the pedicel floral bract.

"Superficially similar to P restrepioides of SUBGENUS Elongatia Luer 1986 However the serrulate petals and a lip flexibly hinged by a bilobulate base exclude it from that SUBGENUS. Within subgenus Effusia the serrulate petals are also an exception but the lip is in full agreemant. It is most similar to the rare P hamiltonii but distinguished by the lareg habit with large, oblong leaves and a stout, equally long ramicaul. From a comparitively small spathe a long, loose raceme of large spotted flowers surpasses the elaf. The narrowly ovate dorsal sepal and synsepal ares similar. Abive the middle the petals are narrowed, thickened and acute with minutely serrates margins. The lip is arcuate with large, erect, marginal lobes that are usually well demarcated from the smaller, apical lobe. Below the lobes the lip is broadly unguiculate and truncate with a lobule at the cornes." Luer 2000
