14. Epidendrum obliquum Schltr. (1912: 457) ( Figure 8E )

Type:— BOLIVIA. Nor Yungas , Unduavi, 3200 m, November 1910, O. Buchtien 2619, (holotype: B. destroyed. lectotype: US! isotypes AMES x2! L! LY!) See Santiago & Hágsater, Epidendrum obliquum in Hágsater & Sánchez 2006: 8: t. 862.

Distribution:— Peru and Bolivia. In Peru it is found in the departments of Cusco and Pasco, present only in the eastern cordillera of the Andes from central to southern Peru; the other records are from Bolivia, although it is quite possible that there are populations in intermediate areas. At present there are only isolated records of the species.

Notes:— Epidendrum obliquum is recognized by the leaves 2–4 cm long, narrowly lanceolate, apex sub-acute, the flowers green, the sepals 8–8.5 mm long, with the margins revolute, and the lip 4.6 × 8 mm, reniform, the apex emarginate. Vegetatively it is similar to E. soratae but that species has flowers somewhat smaller, the sepals 6–7 mm, and the lip reniform with the apex slightly 3-lobed.

Conservation Status:— DD. Data deficient, but it is listed in CITES appendix II.

Examined specimens:— PERU. Pasco: Prov. Oxapampa, Distr. Huancabamba. Milpo, 2950–3100 m, 01 November 2009, van der Werff 23009. ( HOXA! USM!) — Cusco: Calca. Dist. Lares, Choquecancha, Azulcocha , 3823 m, 17 February 2005, L . Valenzuela 4961, (SEL!)
