Type.

ECUADOR. Lehmann 77 (lectotype, designated by Garay (1978: 199): W!; AMES!-drawing, UGDA-DLSz!-drawing).

Diagnosis.

Plants 26-60 cm tall. Leaves 1-3, basal, petiolate; petiole 3-4(8) cm long, narrow, canaliculate; blade 6.5-11 cm long, 2.8-5 cm wide, ovate, acute. Scape erect, enclosed in 6-9 sheaths. Inflorescence 2.5-10.5 cm long, conical, sublaxly many-flowered. Flowers small, glabrous. Floral bracts 4.5-8 mm long, lanceolate, acute. Pedicellate ovary 6-9 mm long, almost glabrous. Dorsal sepal 3-4 mm long, 1-1.1 mm wide, oblong-lanceolate to oblong ovate, acuminate, obtuse, concave, 1-veined. Petals 2.5-3.5 mm long, 0.5-1.2 mm wide, lanceolate, somewhat oblique at base, subobtuse, 1-veined. Lateral sepals 3.5-4 mm long, 1.5-1.7 mm wide, obliquely elliptic-ovate to elliptic-lanceolate, subacute to subapiculate, concave in the centre, obscurely 2-veined. Lip 3-3.3 mm long, 1.6-2.3 mm wide, concave, subsessile, elliptical to oblong-elliptical in outline, obtuse at apex, lateral margins reflexed; disc with numerous, irregularly subglobose thickenings on the inner surface, veins thickened with dendritic branching. Gynostemium 1.2-1.5 mm long. Fig. 10 .

Habitat and ecology.

According to Vásquez et al. (2014) this species grows as an epiphyte in the Yungas ecoregion at altitudes between 2500-3500 m.

Representative specimen.

BOLIVIA. La Paz: PN-ANMI Cotapata, sendero Chojllapata, poco antes de llegar al codo del sendero. 16°14'S, 67°52'O, 2670 m. I. Jiménez 5579 (LPB- Jiménez-Pérez 2011). Fig. 2 .

Notes.

The specimen cited by Jiménez-Pérez (2011) was not found in the Orchid collection deposited in LPB and we were not able to confirm the occurrence of this species in Bolivia. The characteristics presented above are based on those of Ecuadorian and Colombian plants ( Szlachetko and Kolanowska 2019).
