The species is recognized by the prominent, acuminate floral bracts, .8 to 2 " [2 to 5 cm] long, the oblong leaves .8 to 1.6" [2 to 4 cm] wide, the cordate, reniform lip, and the linear 1 to 3 veined petals adnate to the lateral sepals. It is similar to E. palmidium Hágsater, which has narrower leaves, less than .68" [1.7 cm] wide. Epidendrum coriifolium Lindl. has semiterete, fleshy, succulent leaves. Epidendrum alvarezdeltoroi Hágsater has shorter plants, stems with 1 to 2 leaves, and shorter, rounded bracts, and is restricted to the Mexican-Guatemalan border areas. Epidendrum belloi Hágsater has 5 to 7 leaved plants, elongate, narrow floral bracts longer than the perianth, smaller flowers and wider petals .12 to .2" [3 to 5 mm], the lip cordiform, apiculate. Epidendrum beharorum Hágsater has 2 narrow leaves .48 TO 1" [1.2 TO 2.5 cm], successive flowers and is endemic to Chiapas state of Mexico and Guatemala.
