Found in northern Peru near the Ecuadorian border at elevations around 2000 meters as a small to medium sized, cool to cold growing epiphyte with simple, cane-like, new stems arise from the lower internodes of the previous stem, basally terete, laterally compressed above, thin, straight stems enveloped basally by tubular, non-foliaceous, scarious sheaths and carrying 7 to 9, all along the apical half of the stem, distichous, articulate, sub-erect, subcoriaceous, linear-lanceolate, acuminate, margin entire, spreading leaves that blooms in the mid fall on a terminal and lateral, sub-sessile, successively single, few flowered inflorescence with much shorter than the ovary, triangular-ovate, acute, amplexicaul floral bracts and carrying non-resupinate, fleshy, greenish yellow flowers with a white throat and yellow polinia.

"Epidendrum tandapioides 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 is recognized by the thin stems, linear-lanceolate leaves 2.6 to 5" to .2 to .28" [6.5 to 12.5 x 0.5 to 0.7 cm], apical and lateral inflorescence producing one flower at a time, flowers greenish yellow, sepals .8" [20 mm]long, petals linear and the lip slightly 3-lobed. Epidendrum tandapianum Dodson & Hágsater has wider, linear-lanceolate leaves,.28 to .52" [0.7 to 1.3 cm] wide, green flowers, the ovary slightly inflated, sepals .52 to .8" [14 to 20 mm] long, petals linear-oblanceolate, and an entire, triangular lip. Epidendrum triangulabium Ames & C.Schweinf. from Panama, is much smaller overall, has elliptic leaves, .52 to 1.04" x .24 to .52" [1.3 to 2.6 x 0.6 to 1.3 cm], only apical inflorescences, sepals .68 to .58" [11.5 to 12.7 mm] long, linear-oblanceolate petals and a triangular-sagittate lip."
