"Epidendrum jose-alvarezii belongs to the GROUP Andean SUBGROUP Soratae which is characterized by the branching habit starting on a monopodial, primary stem, infundibuliform, rugose leaf-sheaths, lanceolate, aristate, acute leaves, racemose subcapitate inflorescence on a short, thin peduncle, and the bicallose lip. The species can be recognized by the bright carmine-red flowers, sepals .36" [9 mm] long, reniform lip, .24 x .42" [6 x 13 mm], apically shallowly 3-lobed, the apical lobe formed by a pair of wide and short, rounded lobes, the disc of the lip fleshy and turning orange with age. It is somewhat similar to Epidendrum ardens which has bright orange to scarlet to brown flowers, is known only from Cusco, in southern Peru, and has .4 to .44" [10 to 11 mm] long sepals, the lip is reniform cordate, .26 to .28 x .38 to .408' [ 6.5 to 7 x 9.5 to 10.2 mm], the petals linear. Epidendrum soratae Rchb.f. has smaller flowers, sepals .24 to .28" [6 to 7 mm] long, and the lip is .26 x .328" [6.5 x 8.2 mm] long, with the mid-lobe small, comparatively narrower, the flowers greenish-yellow."
