"Epidendrum peraltum belongs to the GROUP Pseudepidendrum is characterized by caespitose plants, cane-like stems, acute to acuminate leaves, apical inflorescence, lacking a spathaceous bract, the petals filiform and the lip usually 3-lobed, with 3 parallel fleshy keels, the apical lobe often bifurcate, and the pollinia “bird-wing” type and SUBGROUP Porphyreum which has flowers colored reddish orange, deep purple or lilac-pink, the calli generally prominent, sometimes horn-like. The species is recognized by the large greenish yellow flowers tinged pink to totally dirty pink, sepals .56 to .64" x .14 to .16" [14 to 16 x 3.5 to 4 mm], lip with the lateral lobes strongly retrorse, the mid-lobe with a short isthmus, parallel sided, ending in a pair of strongly divaricate, linear lobes, column .52" [13 mm] long. Epidendrum capricornu Kraenzl. has somewhat shorter plants, the sepals dorsally purple-brown and ventrally yellowish, the lip bluish purple, with the mid-lobe deltate, and the apical pair of lobes horn-like. Epidendrum porphyreum Lindl. has purple colored flowers, the disc white, sepals .53 to .6" x .2 to .26" [13 to 15 x 5 to 6.5 mm]; the lateral lobes of the lip are ovate-dolabriform, not retrorse, and the mid-lobe has a pair of triangular, slightly divaricate lobes. Epidendrum laeve Lindl. [Syn E ionodesme] has somewhat smaller flowers, violet to dark pink, with the calli white; sepals .4 to .44" x .12 to .16" [10 to 11 x 3 to 4 mm]; lateral lobes of the lip sub-quadrate-dolabriform, only slightly retrorse, column .32 to .34" [8 to 9 mm] long. Epidendrum arnoldi Schltr. has smaller lilac-pink flowers, sepals 8 mm long, lateral lobes of the lip dolabriform, and the column ,24" [6 mm] long. Epidendrum lopezii Hágsater has the largest flowers, sepals .68 to .74" [17 to 19 mm] long, the lip is greenish white with a deep purple splotch in front of the column, and the mid-lobe (which is as long as the lateral lobes), forms a pair of slightly divaricate, apical lobes."
