Found in southern Peru on the Amazon slope of the Cordillera Oriental in wet tropical forests at elevations around 700 meters as a small sized, warm growing terrestrial with simple, cane-like, terete, thin, erect stems carrying 7, all along the stems, unequal in size, apically smaller, elliptic, short acuminate, margin entire leaves that blooms in the late fall on a terminal, without a spathe, occuring only once, peduncle very short, .28" [7 mm] long, rachis slightly flexuous, 4" [10 cm] long, overall, paniculate, shortly branched, about 1" [2.5 cm] long, each subtended by a lanceolate, amplexicaul bract, lax, successively few, 30 flowered inflorescence with prominent, shorter than the ovary, gradually shorter above, linear-lanceolate, acuminate, amplexicaul floral bracts and carrying resupinate, creamy green flowers without fragrance data.

"Epidendrum valenzuelana belongs to the GROUP Arbuscula which is characterized by the erect plants where the new stems originate from the apical internodes of the previous stem, and the Amplexicaule Subgroup which has short-acuminate leaves and lax, few-flowered, paniculate inflorescences with prominent floral bracts. The species is recognized by the creamy-green flowers, the slightly inflated ovary and 3-lobed lip with the lateral lobes obliquely ovate and the mid-lobe oblong, the apex truncate and emarginate. Epidendrum alexii Hágsater & Dodson is vegetatively very similar, but the flowers are white, the lateral lobes of the lip triangular-dolabriform, the mid-lobe acute, entire. Epidendrum amplexirisaraldense Hágsater & E. Santiago has green flowers, the rachis of the inflorescence flexuous, the ovary thin, not inflated and the lip with the base cuneate and the lateral lobes obliquely oblong." Hagsater etal 2013
