Plants 40 cm tall. Leaves 3–5, basal, rosulate, shortly petiolate; petiole up to two cm long; blade up to 10 mm long and two cm wide, lanceolate to oblong lanceolate, acute to acuminate, the uppermost above the base of the stem, ovate, sessile. Peduncle erect, covered by several, partially imbricating sheaths, terminated by a loosely many-flowered raceme about 20 cm long. Floral bracts 10 mm long, ovate-lanceolate, acuminate, glandular-hairy. Pedicellate ovary 13 mm long, glandular-hairy. Dorsal sepal six to seven mm long, two mm wide, oblanceolate to linear-oblanceolate, acute to subobtuse, 3-veined, lateral nerves branching. Petals unguiculate; claw connivent to the column part; lamina five mm long, four mm wide, obliquely triangular, with both ends rounded to blunt, nerves branching from the base of the free part. Lateral sepals six to seven mm
long, three mm wide, ovate-elliptic to ovate-lanceolate, apically falcate, obtuse, nerves 5, branching and anastomozing. Lip unguiculate; claw connate with the column part; disc five mm long and wide, transversely elliptic-cordate, concave in the center, with deltoid or sagittate, blunt apiculus. Gynostemium 2.6 mm long in total, long-stalked
(Fig. 42).
Ecology: No data.
Distribution: Colombia, Cuba, Puerto Rico.

Notes: This species was considered as conspecific with P. racemosa (Walter) C. Mohr by several researchers (D’Arcy, 1987; Bogarín et al., 2014); however, both species differ in flower morphology. In P. glandulosa petals are unguiculate, glabrous on the margin and the lip apical part is deltoid or sagittate.
