"Epidendrum puniceoluteum belongs to the GROUP Secundum SUBGROUP Secundum which is characterized by the caespitose habit, erect, simple, cane-like stems, a normally elongate peduncle of the inflorescence, an erect raceme of generally resupinate, showy, colorful flowers, and a lip adorned by two calli and a median narrow keel. This species, from the southern coast of Brazil, is recognized by the non-resupinate, bright red flowers with yellow calli and mid-rib; sepals .44 to .72" [11 to 18 mm] long, petals elliptic, relatively wide; the deeply 3-lobed lip; the calli linguiform, ascendant, slightly divergent, low, with a prominent mid-rib, laminar, reaching the middle of the isthmus of the mid-lobe; lateral lobes sub-quadrate to sub-flabelliform, posterior margin entire, distal margins deeply laciniate; mid-lobe formed by sub-oblong isthmus in the basal half, apical half bilobed, the lobes divergent, sub-quadrate, the distal margin laciniate. Epidendrum x obrienianum Rolfe being the similar color and overall shape, is distinguished mainly by the narrower, oblong petals, and especially by the calli being wide, linguiform, sub-divergent, ascendant. Epidendrum cryptopateras Hágsater & Courtinard, from Martinique, being the same color and overall shape but having slightly shorter sepals and petals (about 13 mm long), is distinguished mainly by the calli which are narrow, laminar, parallel, erect, semi-elliptic."
