The species is recognized by the laterally compressed, ancipitose stems, 2 large flowers, sepals 1.32 to 1.36" [33 to 34 mm] long, recurved petals and reniform lip, .44 x .72" [11 x 18 mm], with a very small rectangular mid-lobe, lateral lobes obovate with the margin undulate, a long, straight column and slightly erose margin of the clinandrium-hood. Epidendrum anatipedium L.Sánchez & Hágsater, known only from further north, in the State of Ceará, also has large flowers, sepals .146" [36 mm] long, the petals parallel to the column, and obtrapezoid lip with the apex 3-lobed, the lobes triangular, an arched column, and a prominent, erose, clinandrium-hood. Epidendrum carvalhoi Toscano also endemic to Brazil, from the State of Espírito Santo, has long, narrow sepals and petals, sepals 1.48 to 2.2" [37 to 55 mm] long), the lip is obreniform, 3-lobed, mid-lobe small, short and wide, rounded, apiculate. Epidendrum latilabre Lindl. is widely distributed along the Mata Atlântica of Brazil, sepals are -72 to 1.33# [18 to 33 mm] long, petals spreading, lip is 4 times wider than long, lateral lobes sub-quadrate, mid-lobe wide and deeply emarginate, forming a pair of lobes, and the prominent clinandrium-hood has a deeply lacerate margin. Epidendrum oldemanii Christenson is endemic to the French Guyana and has smaller flowers, sepals .56 to .66" [14 to 16.5 mm long, spreading petals, a bilobed, transversely reniform lip with the margin sinuous and subglobose calli. Epidendrum amapense Hágsater & L.Sánchez, from northern Brazil and the French Guyana has 1 to 2, smaller flowers, sepals .56 to .68" [14 to 17 mm] long, spreading petals, semi-ovate lateral lobes with the margin slightly erose, mid-lobe is short and wide, .48 x 1.2" [1.2 x 3.0 mm], emarginate, the column slightly arching with the margin of the clinandrium-hood deeply erose-dentate. Epidendrum pseudodifforme Hoehne & Schltr. also endemic to coastal Brazil has terete stems, 5 to 8 small flowers, sepals .48 to .52" [12 to 13 mm] long, spreading petals, a 3-lobed lip with the margin crenulate, and the mid-lobe with a wide sinus forming 2 rounded lobes."
