"Epidendrum yaracuyense, from Venezuela, which has belongs to the GROUP Difforme , which is characterized by the sympodial, caespitose habit, fleshy, light green to glaucous leaves, apical, sessile inflorescence lacking spathaceous bracts, rarely with a short peduncle, inflorescence one-flowered to sub-corymbose, flowers green to yellowish-green, rarely white. The species is recognized by the the apiculate apex of the leaves, the lip reniform, only slightly cordate at the base, margin entire, with two small, sub-globose calli and an arched column. Epidendrum holtonii has ancipitose stems, and the transversely elliptic-reniform to obscurely 3-lobed lip, the base deeply cordate, the basal margin undulate, lateral lobes elliptic, midlobe very small, forming two small, rounded lobes, the apex with a wide, apiculate sinus, and the small, divergent calli. Other species which could be confused with this species grow in the Amazon basin of Peru such as E. apaganoides D.E.Benn. & Christenson which has a 3-lobed lip, the disc fleshy, and a slightly arching column. Epidendrum apaganum Mansf. has smaller leaves, the lip 3-lobed, small, sub-globose calli, and the disc of the lip with numerous thickened veins. Epidendrum pseudoapaganum D.E.Benn. & Christenson has large plants with numerous flowers, and the lip reniform without thickened veins."
