Found in north central Peru on mossy tree trunks near the ground in lower wet montane forests at elevations of 1800 to 2000 meters as a medium sized, cool growing epiphyte with cane-like, sinuous, basally terete, laterally compressed above, simple, new canes arise from near the base of the previous stem carrying 4 to 6, equidistant, all along the upper half of the stem, linear-lanceolate to elliptic, acute, margin entire, carinate leaves that blooms in the late summer and early fall on a terminal, on a mature stem, arising through a narrow, acuminate and oblique spathe, occuring only once, racemose, erect, peduncle 1.2" [3 cm] long, rachis [1.2 to 1.4 cm] long, simultaneously 5 to 6 flowered inflorescence with much shorter than the ovary, linear, acuminate floral bracts and carrying non-resupinate, non-fragrant, greenish white flowers with the exterior of the sepals and petals tinged with red brown.

"Epidendrum yambrasbambense belongs to the GROUP Herrenhusanum characterized by the caespitose, sympodial habit, the erect racemose inflorescence subtended by a narrow, long spathe, and non-resupinate flowers. The species is recognized by the straggling habit, flattened stems, few linear-lanceolate to elliptic, narrow leaves, narrow, acuminate and oblique spathe, and erect inflorescence with few non-resupinate flowers, 3-lobed lip and linear acuminate petals. Epidendrum trilobochilum has much wider leaves, a usually single branched inflorescence, the floral bracts longer to much shorter than the ovaries, resupinate flowers with a deeply 3-lobed lip, the lateral lobes slightly smaller than the cuneate midlobe. The plants are similar to but larger than those of E. fruticetorum which has wider leaves, wider petals, a clearly bilobed midlobe, and erose margins." Hagsater etal 2001
