" 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
