"Epidendrum coconucoënse belongs to the GROUP Pseudepidendrum which is characterized by the caespitose habit, un-branched stems, apical, branched inflorescence, no true spathaceous bract, and the flowers with a long, thin column, a 3-lobed lip with the mid-lobe generally bifid and divaricate, and filiform petals, and SUBGROUP Porphyreum which has variously colored flowers, not green with the apex of the column and lip white. 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."
