Plants up to 50 cm tall. Leaves 5–7, basal, rosulate, petiolate; petiole up to three cm long, narrow; blade up to 10 cm long and three cm wide, ovate-lanceolate to oblanceolate, acute, glabrous. Peduncle erect, slender to relatively stout, glandular above lower third, otherwise glabrous, with up to six cauline sheaths, terminated by a sublaxly many-flowered raceme up to 17 cm long. Flowers green with cream margins. Floral bracts up to 15 mm long, lanceolate, glandular. Pedicellate ovary up to nine mm long, densely glandular. Sepals almost glabrous. Dorsal sepal six mm long, 1.5 mm wide, ligulate, obtuse, obscurely 3-veined. Petals unguiculate; claw free part 1.5 mm long, narrow; lamina seven mm long, 3.2 mm wide, obliquely elliptic-ovate in the lower part, ligulate above, obtuse at both ends,
auriculate basally, 2-veined, veins branching, margins glabrous. Lateral sepals seven mm long, three mm wide, ovate-lanceolate, subobtuse, somewhat falcate, free to the base, 5-veined. Lip unguiculate, claw about 1.5 mm long; lamina 5.2 mm long in total, 5.5 mm wide when spread, obreniform in general outline, subcordate at the base, concave in the center, glabrous, nerves 5, branching, apical projection 1.2 mm long and 0.5 mm wide, linear-ligulate, obtuse. Gynostemium five mm long (Fig. 8).

Ecology: Terrestrial in premontane forest. Flowering in April, May, October, November, and December

Notes: This species is similar to P. micromystax from which it can be distinguished by unguiculate petals and lip. In both cases the claws measure ca 1.5 mm long.
