"Epidendrum englerioides belongs to the GROUP Pseudepidendrum SUBGROUP Porphyreum, characterized by caespitose plants, cane-like stems, acute to acuminate leaves, the apical inflorescence, lacking a spathe, the petals filiform, the lip usually 3-lobed, with 3 parallel fleshy ribs, the apical lobe often bifurcate, and the pollinia “bird-wing” type; The species is recognized by the sepals and petals bright green with the apex of the column and lip white, the sepals about 10 mm long, and the 3-lobed lip with the lobes of the mid-lobe longer than the ovate lateral-lobes of the lip which are slightly retrorse. Epidendrum englerianum has a lax, few-flowered inflorescence with the sepals and petals deep purple, the apex of the column and lip pink, sepals reflexed, .4 to .52" [10 to 13 mm] long, the base of lip deeply cordate, lateral lobes falcate-retrorse, wider between the lateral lobes than between the apical bilobed mid-lobe, and the lobes are proportionately shorter and wider, and the calli thin, prominent. Epidendrum jasminosmum Hágsater & Dodson has somewhat similar flowers, but plants are large to 28" [70 cm] tall, the leaves are elliptic 3.2 to 6" [8 to 20 cm] long, the inflorescence is a many-flowered panicle, and flowers are pale green turning yellow, the apical half of the column and lip white, strongly fragrant of Jasmin, the sepals are .4 to .52" [10 to 13 mm] long, the lateral lobes of the lip are sub-rectangular, slightly arching forward, and the bifid mid-lobe has long, falcate, oblong lobes, the width between the lateral and the mid-lobes about equal."
