Common Name The Sawfish Pleurothallis

Flower Size .2" [5 mm]

Found in Tolima, Cauca and Putumayo departments of Colombia and Ecuador at elevations around 2800 to 3300 meters as a small sized, a cold growing epiphyte with ascending, slender ramicauls enveloped by 2 loose, tubular sheaths and carrying a single, apical, erect, coriaceous, narrowly elliptical, acute, narrowly cuneate below into the petiolate base leaf that blooms in the fall and earlier winter on an erect, subdense, distichous, 6 to 14" [15 to 35 cm] long including the 3.2 to 6" [8 to 15 cm] long peduncle, simultaneously several, many flowered inflorescence arising laterally from below the apex of the ramicaul with acute, acuminate floral bracts.

"This species is one of the few pleurothallids that can be recognized dead or alive. It is a large species with a scandent, prolific habit and acute, petiolate leaves. The distinctive, long, many-flowered racemes with two opposing rows of long, pointed, floral bracts reminded Kränzlin of a sawfish, hence Pleurothallis pristis F. Lehm. & Kraenzl. The unexpanded sepals are obtuse and connate below the middle. The petals are simple, 3-veined and broadly obovate. The lip is concave below a bilobed bar." Luer 2018

Luer in 2018 puts S dendrophila as a synonym of this species but Kew maintains their separate species status.
