Found in southern Peru on the upper ridge of the Amazon slope at elevations of 2500 to 4600 meters as a medium sized, cold growing epiphyte with a simple, cane-like, terete, thin, straight stem that produces a new stem from the subapical node of the previous stem and carrying 3, aggregated towards the apex, narrowly elliptic, acute, smooth, spreading leaves that blooms at most any time of the year on a terminal, occuring only once, racemose, arching-nutant, laterally compressed, laxly few [8 to 12] flowered inflorescence with floral bracts that are nearly as long as the ovary, linear to triangular, acuminate, basally conduplicate floral bracts and carrying simultaneoulsy opening, resupinate, fleshy flowers.

"Epidendrum marcapatense belongs to the GROUP Arbuscula SUBGROUP Incomptum, characterized by the sympodial habit, the new growth produced from the mid-nodes of the previous cane-like growth below the leaves, the apical inflorescence flowering one time only, and the roots produced at the base of each new growth, not at the intermediate nodes, the flowers fleshy. The species is recognized by the.36 to .4" [9 to 10 mm] long sepals, the lip is bilobed, reniform, base cordate, apex emarginate, margin erose. Epidendrum nephroglossum Schltr. has comparatively wide, acuminate floral bracts, a .52" [13 mm] wide lip, the sepals being .44" [11 mm] long, and the petais linear-oblanceolate and somewhat acuminate, it was described from the Chanchamayo valley in Junín province of Peru. It is similar to E. latisegmentum C. Schweinf. which has larger flowers, sepals .72 to .84" [18 to 21 mm] long, a thin uninflated nectary, a íarge, bilobed, reniform lip, and the relatlvely wide sepals and petals. Epidendrum marsiorum R. Vásquez & Ibisch, has an entire lip about .36" [8 mm] wide, sepals .36 to .4" [9 to 10 mm] long, and leaves 2 to 4.8" x .4 to .8" [5 to 12 x 1 to 2 cm], and is found in eastern Peru and neighboring Bolivia. It is somewhat similar to Epidendrum fujimorianum D. E. Benn. & Christenson which has a 4 lobed lip, the apical lobes small and semicircular." Hagsater etal 2007
