"Epidendrum yambrasbambense belongs to the 2001 GROUP Herrenhusanum and 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
