"The species is recognized by the small, fleshy, pink flowers the sepals and lip unevenly blotched purple, especially the disc of the lip, sepals .44 to .48" [11 to 12 mm] long. Epidendrum falsiloquum has smaller, ochre-yellow flowers, the lip white, with 3 to 5 purple lines over the ribs of the disc, sepals .28 to .32" [7 to 8 mm] long. Epidendrum arnoldii Schltr. has even colored purple-pink flowers, the disc and calli pink to white, sepals .32 to .4" [8 to 10 mm] long, the lip convex in natural position. Epidendrum laeve Lindl. is very similar, but the basal lobes of the lip dolabriform-falcate, and the apical-lobe slightly arching upwards, not convex in natural position. Epidendrum peraltum Schltr. has somewhat larger flowers with sepals .56 to .64" [14 to 16 mm] long, colored greenish yellow to a dirty pink, the lip spreading in natural position, with the lateral lobes strongly retrorse, and the mid-lobe forming a pair of divaricate, linear lobes. Epidendrum porphyreum Lindl. has purple flowers with the disc white, sepals .52 to .6" [13 to 15 mm] long, the lateral lobes of the lip ovate-dolabriform, not retrorse, and the mid-lobe is formed by a pair of triangular lobes."
