Found in Azuay province of Ecuador and the departments of Amazonas and San Martín Peru, on the eastern slope of the Cordillera Oriental in wet montane forest at elevations of 3200 to 3525 meters as a small sized, cold growing epiphyte with cane-like, straight, terete at the base, laterally compressed above, originating from the sub-apical internodes of the previous stem, progressively shorter, from a long primary stem carrying 3 to 8 on the branches, distributed along the apical 2/3 of the stems, slightly arched; sheaths slightly infundibuliform, striated and rugose; blade lanceolate, acute, sub-coriaceous, with a low dorsal keel, margin minutely crenate leaves that blooms in the spring, summer and fall on a terminal, without a spathe, peduncle ca. .4 to .6" [1.0 to 1.5 cm] long, racemose, arching successively most, 4 to 12 flowered inflorescence with much shorter than the ovary, the basal one large, progressively shorter, triangular, acute to acuminate floral bracts and carrying yellow to orange-yellow flowers with fragrance during the evening, disagreeable, of rotten mushrooms.

" Epidendrum yasgolgaënse belongs to the GROUP Andean SUBGROUP Soratae recognized by the monopodial stem with subapical branching, the infundibuliform leaf-sheaths and the acute leaves. The species is recognized by the yellow to orange-yellow flowers, the spreading sepals and petals, the dorsal sepal .3" [7.5 mm] long, the lip entire, orbicular-reniform, base deeply cordate, apex mamillate, margin hyaline, erose. Epidendrum ardens Kraenzl. stands out due to the colorful flowers in a compact raceme, in bright tones of scarlet red, orange, or rarely yellow or reddish brown, the somewhat conduplicate, acute leaves, and the partly spreading cupped sepals .4" [10 mm] long with the lip reniform, deeply cordate and somewhat emarginate. Epidendrum soratae Rchb.f. has greenish yellow flowers, sepals .24 to .28" [6 to 7 mm] long, lip 3-lobed, reniform, with a small triangular, emarginate lobe, margin entire." Hagsater etal 2018
