"Epidendrum centronum belongs to the GROUP Andean SUBGROUP Vernixium, characterized by the monopodial, branching stems, erect inflorescences, lax flowered, the flowers non-resupinate, the lip more or less 3-lobed. The species is recognized by the oblong-lanceolate to oblong-elliptic, .32 to .52" [8 to 13 mm] wide leaves, the short peduncle of the inflorescence, 1.4" [3.5 cm] long, 6 successive, green flowers, the lip tinged brown, sepals .8 to .84" [20 to 21 mm] long, prominently aristate, and the panduriforme lip, slightly longer than wide. Epidendrum pozoi Hágsater & Dodson is vegetatively very similar, but the inflorescence is longer, 2.4 to 4" [6 to 10 cm] long, the flowers green, concolor, (turning yellow with age), the ovary elongate, .136 to .248" [34 to 62 mm] long, and the lip clearly 3-lobed. Epidendrum panduratum Hágsater & Dodson has wider, ovate-elliptic leaves, the apex retuse, the densely, 6 to 12 flowered inflorescence of simultaneous, pink-green flowers, the sepals .6 to .64" [15 to 16 mm] long and minutely apiculate."
