This species is said to be synomonous with E hartii so if true then this name takes precedence.

"Epidendrum subpurum Rchb.f. belongs to the GROUP Amblostoma SUBGROUP Amblostomioides recognized by the sympodial habit, with somewhat fusiform-thickened stems, sub-coriaceous, bilobed leaves, paniculate inflorescence, and ovary or flowers often pubescent, lip 3-lobed. The species is recognized by a racemose inflorescence, laxly few-flowered, sepals .32" [8 mm] long, lateral lobes of the lip ovoid, acute. Epidendrum sanctae-rosae has nutant, many-flowered inflorescence, the flowers densely packed throughout the branches, on very short ovaries; the flowers small, sepals .24 x .12" [6 x 3 mm], disc of the lip provided with 3 very short, prominent ribs, reaching the base of the midlobe, united at the base, apically narrowly rounded, the mid-rib straight, the lateral ribs divergent, formed by a simple rib with a wider, sulcate rib on top; lateral lobes .08 x .12" [2 x 3 mm], transversely elliptic; mid-lobe .1 x .1" [2.5 x 2.5 mm], sub-quadrate, corners rounded, apex somewhat emarginate. Epidendrum purum Lindl. has oblong leaves 6.24 to 8.32" x .52" [15.6 to 20.8 x 1.3 cm], an erect inflorescence with larger flowers, sepals .48 to .52" [12-13 mm] long, narrowly lanceolate, acuminate, dorsal sepal spreading, petals linear, spreading, and the apex of dolabriform lateral lobes of the lip acute.
