"Epidendrum oaxacanum is part of GROUP Anisatum and is an Oaxacan endemic with lax inflorescence, greenish-yellow flowers, lip 3-lobed but with the lobes separated by narrow, acute sinuses, lateral lobes with several radiating, thickened veins, and midlobe shallowly emarginate, with margin erose. The species is closely related to Epidendrum guerrerense which has short, dense racemes, green flowers, broad obtuse sinuses separating the lobes of the 3-lobed lip, the midlobe is definitely bilobed, with entire margins, and the lateral lobes lack the thickened veins. Epidendrum guerrerense has been found growing sympatrically with E. hueycantenangense Hágsater & Garcla-Cruz, which can be easily distinguished by the usually purplish flowers, and the obscurely 3-lobed lip with dentate margins.
