"Epidendrum transversellipticum belongs to the GROUP Alberti SUBGROUP Physinga recognized by the caespitose habit, ancipitose stems, long, nude, two-winged peduncle and the raceme of imbricating bracts with flowers produced singly in succession. The species is recognized by the small habit, .12" [3 mm] long bracts, .24" [6 mm] long sepals, transversely elliptic, entire lip and the prominent, straight clinandrium. Epidendrum jefeallenii Hágsater & Carda-Cruz is much larger overall, the sepals .4 to .44" [10 to 11 mm] long, the column .32" [8 mm] long, and the cordiform, emarginate lip .16 to .2" x .2 to .24" [4 to 5 x 5 to 6 mm] in size. Epidendrum maduroi Hágsater & Carda Cruz is still larger, with stems 8 to 12" [20 to 30 cm] long, with sepals .48 to .6" [12 to 15 mm] long, subreniform lip .24 to .32" [6 to 8 mm] wide and a short clinandrium. Epidendrum panamense Schltr. has an ovate, subcordate, acuminate lip and the ovary somewhat inflated into a vesicle." Hagsater etal 2001
