"Epidendrum choccei belongs to the GROUP Frutex recognized by the caepitose habit, usually simple stems, lanceolate leaves, lacking spathes, nutant racemes, widely cordiform to reniform lip and SUBGROUP Leptanthum Subgroup which si caracterized by the thin stems, scarecely branched when mature, leaves short, linear-lanceolate to lanceolate oblong, nearly parallel to the stem, inflorescence arching-nutant, apical and lateral in mature stems, racemose to paniculate, few-flowered. The species is recognized by the narrowly lanceolate leaves flat, 1.08" to 1.6" X ,12 TO ,24" [27 to 40 × 3 to 6 mm], parallel to the stem, flowers fucsia-rose colored, disc of the lip white, sepals .332 x .08 to .94" [8.3 x 2.0 to 2.3 mm], narrowly elliptic to semiovate-lanceolate, acuminate, lip .22 x .24" [5.5 x 6.0 mm], widely ovate the base truncate, apex acuminate. Epidendrum podocarpense Hágsater & E.Santiago is vegetatively similar, but the leaves larger, flat, 1.4 to 2.2" x .24 to .32" [35 to 55 x 6 to 8 mm], flowers fucsia, with the disc of the lip white, sepals .32 to .332" x .12 to .16" [8.0 to 8.3 x 3.0 to 4.0 mm], elliptic to narrowly elliptic, acute, lip .24 x .36" [6 x 9 mm], widely cordiform, base cordate, apex rounded. Epidendrum leptanthum Hágsater is vegetatively similar, leaves are 1.04 to 3.2" x .16 to .28" [26 to 80 x 4 to 7 mm], flowers greenish white, dorsally tinged reddish brown, sepals are oblong to ovate-oblong, acute, lip .24 x .28" [6 x 7 mm], widely cordiform, base cordate and apex acute.
