"Epidendrum tandapianum belongs to the GROUP Tandapianum, which is recognized by the subcaespitose habit, the 2-ranked leaves facing one side of the stem, and the inflorescence producing single flowers, with a large triangular or 3-lobed, bicallose lip. The species has linear-lanceolate leaves 2 to 6" x .28 to .52" [5 to 15 x 0.7 to 1.3 cm], green flowers, an inflated ovary, sepals .56 to .8" [14 to 20 mm] long, linear-oblanceolate petals and an entire, triangular lip. Epidendrum tandapioides Hágsater has thinner stems, narrower leaves, .26 to 5" x .02 to .28" [6.5 to 12.5 x 0.5 to 0.7 cm], the ovary is not inflated, linear petals, and the lip somewhat 3-lobed. Epidendrum triangulabium Ames & C.Schweinf. from Panama has much smaller plants, elliptic leaves, smaller flowers and a triangular-sagittate lip." Hagsater etal 2009
