Plants up to 40 cm tall. Leaves 1-3, basal, often variegated, petiolate; petiole rather variable in length, up to 3 cm; blade up to 9 cm long, 4 cm wide, ovate to ovate-lanceolate, acute to subacuminate, subcordate at base. Scape slender, erect, remotely few-sheathed, glabrous below, glandular-pubescent above. Inflorescence up to 6.5 cm long, cylindrical, loosely to subdensely many-flowered. Flowers white with green veins. Floral bracts 4 mm long, ovate-lanceolate, acuminate, sparsely glandular. Pedicellate ovary up to 6 mm long, cylindrical, more or less glandular. Dorsal sepal up to 3.5 mm long, 1.6 mm wide, erect, elliptical, subacute to subobtuse, 3-veined, occasionally sparsely pubescent dorsally. Petals up to 3.1 mm long, 1 mm wide, near apex linear-oblanceolate, acute to obtuse, 1-veined, glabrous along margins. Lateral sepals up to 4 mm long, 1.6 mm wide, spreading, obliquely ovate to ovate-elliptical, acute to obtuse, 2-veined, occasionally sparsely pubescent dorsally. Lip up to 3.6 mm long, 3.2 mm wide, concave, inconspicuously subcordate at base, ovate to broadly elliptical in outline, subacute to subobtuse; disc obcordately papillose-thickened with three branching, often glandular (with nodules) veins from base to middle of lip.

Notes.
The specimen cited by Vásquez et al. (2014) was not found in the Orchid collection in LPB and we were not able to confirm the occurrence of this species in Bolivia. The characteristics presented above were prepared based on those of Ecuadorian and Colombian plants ( Szlachetko and Kolanowska 2019).
