The species is recognized by the ascending leaves almost parallel to the stem, the rhombic, acute, 2-veined petals, and the widely triangular lip. Epidendrum oxycalyx Hágsater & Dodson has narrower, acuminate floral segments. Epidendrum palaciosii Hágsater & Dodson has flowers about 1/3 the size, the sepals muriculate outside, without keels. Epidendrum obovatipetalum Hágsater & Dodson has wider leaves, rounded floral segments and oblanceolate petals." Hagsater etal 1993
