Found in northern Peru on the Cordillera Occidental of the Andes just east of the Continental Divide, at elevations around 2800 meters as a small sized, cold growing epiphyte with cane-like, terete, produced from the basal internodes of the previous stem, straight, thickened, green tinged stems partly covered when young by 2 green thin non-foliar striated sheaths, turning brown with age and carrying 1 to 4, distributed along the apical half of the stem; sheath tubular, striated, short; blade lanceolate, acute, coriaceous-succulent, articulate, green, margin entire, spreading leaves that blooms in the later summer on a terminal, arising through a single, conduplicate, narrowly elliptic, acute, .48 to 1" [1.2 to 2.5 cm] long spathe, the spathe is located at the apex of a short laterally compressed peduncle, peduncle ca. .96" [2.4 cm] long, laterally compressed, short, below the spathe, rachis above the spathe terete; rachis short, up to 3.2" [8 cm] long overall including the flowers, apical, laxly simultaneously 2 to 3 flowered inflorescence with much shorter than the ovary, triangular, acute, embracing floral bracts and carrying nonresupinate, the ovary turned over 90° so that the flower produced from the left side of the rachis is oriented slightly towards the right and vice-versa by way of the arched ovary and the column forming a 90° angle with the ovary, fleshy, lustrous, greenish flowers with the anther pale green and the fragrance was not registered.

" Epidendrum amphorastele belongs to the GROUP Filamentosumwhich is characterized by the caespitose habit with thickened stems, with 1 to 4 fleshy, coriaceous leaves, the inflorescence apical, distichous, with successive non-resupinate flowers, the lip entire, bicallose, margin fimbriate to entire. The species is recognized by the pendent habit, single-leafed thickened stems, peduncle with a prominent spathe, and the non-resupinate flowers with a prominent anchor-shaped lip. The flower is reminiscent of that of Epidendrum cuchibambae Schltr. but the plant of that species is erect with several leaves on the thin stem. The plant is reminiscent of that of Epidendrum moronense, pendent, with a single apical, coriaceous, succulent apical leave in mature plants. Epidendrum moronense has thickened stems 1.6" [4 cm] long, non-resupinate flowers, greenish to pinkish or buff, the lip white sometimes tinged with pale pink, column green, anther white, strongly reflexed sepals and petals nearly as long as the ovary, and the lip is reniform to sub-orbicular, with the margin deeply laciniate. Epidendrum ruizlarreanum D.E.Benn. & Christenson with a single linear leaf, has white, concolor flowers, spreading sepals, petals parallel to the column, the oblong-ovate un-lobed lip with the margin fimbriate, high laminar calli, and 3 narrow ribs, the reniform anther is truncate."
