"Epidendrum marsiorum R. Vásquez & Ibisch, belongs to the GROUP Arbuscula SUBGROUP Incomptum, characterized by the syympodial 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 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. Epidendrum marcapatense has .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.
