Found in Colombia and Ecuador at elevations around 1800 to 2900 meters as a medium to large sized, cool to cold growing epiphyte or terrestrial on steep embankments with simple, new stem arising from the lower internodes of the previous stems, cane-like, terete, basally, laterally compressed towards the apex, thin, straight stems basally enveloped by tubular, non-foliar, scarious sheaths and carrying 9 to 10, all along the apical 1/2 of the stem, distichous, articulate, sub-erect, sub-coriaceous, linear-lanceolate, acute, minutely apiculate, margin entire leaves that blooms in the winter, spring, summer and fall on a terminal and lateral, peduncle ancipitous, nearly totally enveloped by 2 tubular, ancipitous, acuminate, scarious bracts, the terminal raceme is elongate, successively single, several flowered inflorescence with much shorter than the ovary, triangular, ovate, acuminate, amplexicaul floral bracts and carring non-resupinate, fleshy, green, without fragrance flowers.

"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
