"Epidendrum cochabambanum Dodson & Vasquez belongs to the GROUP Diothonea SUBGROUP Diothonea which is characterized by the branching plants, linear-lanceolate to oblong leaves, the apex bilobed, racemose, arching-nutant inflorescence membranaceous, rarely fleshy flowers, the entire to 3-lobed, ecallose lip with the margin erose and with or without 1 to 10 thin, smooth to erose keels, the column completely free to obliguely united to the lip, the anther reniform. The species which has linear petals .32 to .6" [0.8-1.5 mm] wide, and a transversely elliptic lip with the apex slightly 4-lobed, and forming a wide throat with the column. Epidendrum amaruense is recognized by the small, non-resupinate, yellow to ochre-green flowers sepals .16 to .2" [4 to 5 mm] long with wide floral segments, the ovate petals .16" [4 mm] wide and the lip reniform, bilobed. It is similar to Epidendrum jativae Dodson which shares the non-resupinate flowers, but has longer leaves, up to 4" [10 cm] long, .6" [1.5 mm] wide, oblong petals, and the 3-keeled lip, 3-lobed with the midlobe small and itself bllobed. It is vegetatively similar to Epidendrum gastrochilum Kraenzl., also from Peru, has much larger flowers with the sepals .44 to .52" [11 to 13 mm] long and the lip is ovate-orbicular with 6 laminar keels, has a much longer column .36 to .4" [9 to 1.0 mm] long, and shares the curious narrow cavity on the underside of the column, which is accessed through a narrow, elongate slit, a feature first described in the Colombian Epidendrum cleistocoleum Hágsater & Santiago and shared by Epidendrum cottoniiflorum [Rchb.f.) Hagsater." Adapted from Plate 847 Hagsater etal 2006
