"Epidendrum tamaense belongs to the GROUP Arbuscula SUBGROUP Incomptum, which is characterized by the stems produced from the middle of the previous stem, with few, large leaves aggregate near the apex of the stem, the nodding raceme of relatively large, fleshy, basically green flowers, the thin ovary, not forming an inflated vesicle. The species is recognized by the fleshy, large, green to olive-green flowers turning yellowish, the lip marked with purple, the aristate sepals, obtrullate, 3-veined petals, the 3-lobed lip with the lobes subequal in size, the lateral lobes suborbicular, the midlobe obcuneate, deeply emarginate, forming two rounded lobules. The Venezuelan form has somewhat smaller leaves, a slightly shorter, straight column, longer floral bracts, and the flowers with more acuminate, light green tepals, with the column and lip dull peachy yellow to buff with very faint pink venation . The Ecuadorean E. homoion Hágsater & Dodson is similar, but that species is somewhat smaller, the sepals and petals shorter, and the .52 to .64" [14 to 16 x 26 to 28 mm] lip has semiorbicular lateral lobes, and a smaller midlobe. Epidendrum incomptum Rchb.f. and E. yambalense Hágsater & Dodson have acute or apiculate midlobes." Hagsater etal 2006
