"Epidendrum leimebambense Hágsater, belongs to the GROUP Ventricosum which is recognized by the sympodial habit, few leaved stem, prominent spathaceous bract and the resupinate flowers mostly bright purple, with a wide, smooth nectary that does not penetrate the ovary. is also similar, The species has wide leaves, up to .68" [1.7 cm] wide, flowers larger, sepals .56 to .64" [14 to 16 mm] long, pale green marked with purple, and cordiform lip, .36 x .44" [8 x 11 mm]. Epidendrum amethystinum has erect, somewhat thickened stems with very coriaceous, narrower leaves, with a raceme of bright violet, crystal-like, flowers opening from the apex of the scape backwards, subtended by a single narrow, spathaceous bract; there is nectar overflowing from the nectary into the concave lip in front of the calli; the color of the flowers is like that of Nageliella. Epidendrum ventricosum Lindl. has sub-caespitose habit, medium sized plants with ancipitose stems the leaves are long and narrow 1.6 to 4.8" x .12 to .32" [4 to 12 x 0.3 to 0.8 cm], the lip is as wide as it is long, and the calli are small, about ¼th the length of the lip. Epidendrum pachygastrium Kraenzl. is very similar and is distinguished by the shorter, narrower lanceolate leaves 1.2 to 3.2" x .24 to .4" [3 to 8 x 0.6 to 1.0 cm], and the lip slightly wider than long and with the two large, sub-globose calli nearly half as long as the lip.

"Epidendrum leimebambense is also similar to E. buchtienii Schltr., but differs in the scandent habit and the cordiform lip with entire margins." Hagsater etal 1993
