Plants ca 10–25 cm tall. Leaves 5–9, basal, rosulate, shortly petiolate; blade two to three cm long, 0.5 cm wide, oblong lanceolate to linear-oblanceolate, acute to subobtuse, glabrous. Peduncle erect, delicate, glabrous below, pubescent above, 3-sheathed, terminated by a laxly many-flowered raceme about three to eight cm long. Flowers small, sepals pubescent-glandular on the outer surface. Floral bracts ca five mm long, lanceolate, pubescent-glandular. Pedicellate ovary up to nine mm long, densely pubescent-glandular. Dorsal sepal up to five mm long, two mm wide, oblong-lanceolate, subobtuse, 3-veined. Petals 3–3.5 mm long, about two mm wide, prominently unguiculate; claw linear, narrow; lamina narrowly falcate-triangular in outline, with acute both ends, the lower one with prominently elongate outer margin, veins 2, sparsely branching, margins glabrous. Lateral sepals up to six mm long, two mm wide, free to the base, obliquely lanceolate-ovate, subobtuse, 3-veined. Lip three mm long, up to three mm wide, unguiculate; claw U-shaped, with single, transverse callus at the base; lamina obcordate in general outline, widest near the middle, apically 3-lobed; middle lobe linear-lanceolate, subacute, exceeding both laterals; lateral lobes semi-elliptic-obovate, rounded. Gynostemium shortly stalked, erect (Fig. 12). Ecology: Terrestrial. Flowering in December and January. Distribution: Colombia. Alt. 600 m.
Notes: This species shares with other representatives of P. venusta group the similar lip shape, which in general outline is obcordate with much elongate apical middle lobe. The character which separates it from other species is the form of petal, which is narrowly falcate-triangular in outline, with acute both ends and prominently elongate outer margin.
