Found in Valle de Cauca department of Colombia on the western slope of the central Codillera in secondary, humid, cloud forests at elevations around 3500 meters as a small sized, cold growing epiphyte with terete, new stem arising from subapical internode of the previous stem carrying 3, towards the apex, unequal in size, subcoriaceous, alternate, articulate, obovate-elliptic, obtuse, margin entire leaves that blooms in the late winter and early spring on a terminal, without a spathe, occuring only once, peduncle .64” [1.6 cm] long, terete, thin, straight, 2.16” [5.4 cm] long overall, successively few, 10 to 15 flowered inflorescence with half as long as the ovary, triangular, acuminate, amplexicaul floral bracts and carrying yellow, non fragrant flowers.

"Epidendrum luis-sanchezii belongs to the GROUP Arbuscula which is characterized by the erect habit with successive lateral growths produced from the middle of the previous growth, few leaves aggregate towards the apex of the stems, roots generally only from the base of the primordial stem, and the SUBGROUP Incomptum which has a short apical inflorescence with fleshy yellowish to green to violet-green to black flowers with short ovaries, the lip entire to 3- lobed. The species is recognized by obovate-elliptic leaves, the yellow flowers, sepals with a prominent, acute and a serrulate keel on the ventral side, the apical 1/4 of the petals hidden beneath the ecallose lip which is obscurely 3-lobed, the mid-lobe emarginate, apiculate, forming a pair of rounded lobes, with a low thick rib running the length of the lip. Epidendrum aylacotoglossum Hágsater has elliptic leaves, the clearly 3-lobed lip with a pair of low calli and a short canal in the middle, and the column sigmoid. Epidendrum envigadoënse Hágsater has narrow, lanceolate leaves, a wider lip .682" to .76" [17.5 to 19 mm] with a pair of small calli and the apex emarginate, not apiculate. Epidendrum amayense Hágsater has linear-lanceolate leaves .2 to .24" [.5-.6 mm] wide, somewhat smaller, green flowers, the sepals .36" [9 mm] long with a low dorsal keel, and the lip without any thickened rib. Epidendum oligophyllum F.C. Lehm. & Kränzl. is vegetatively very similar, with oblong-elliptic to elliptic leaves, olive-brown flowers, the lip bicallose and the column .4" [10 mm] long. Epidendrum morae P.Ortiz, Hágsater & L.E.Álvarez has elliptic leaves, pale yellow flowers somewhat tinged pink-violaceous, the sepals have no dorsal keel, and the 3-lobed lip is bicallose with 3 low ribs on the disc."
