"Epidendrum tenuispathum C. Schweinf. belongs to the GROUP Excisum SUBGROUP Excisum which is characterized by the sympodial, caespitose habit, canelike stems with numerous leaves, the inflorescence racemose or an open panicle with few, elongate branches, the 1-2 large spathaceous bracts at the base of the inflorescence, and the 3-lobed lip and medium sized flowers. The species is recognized by the terete stem, lanceolate, acute, dark green leaves with the underside reddish, with an erect, paniculate inflorescence, and the lip is wider than long. Epidendrum lesteri has terete stem, lanceolate, acute, dark green leaves with the underside reddish, the pink colored, subacute spathe, nutant, densely f1owered inflorescence branching near the base into several similar racemes, and the greenish, pale burgundy-red tinged flowers; the lip deeply cordate. It closely resembles Epidendrum orthoclinium which has narrower leaves, a more lax-flowered inflorescence, smaller, greenish yellow flowers, acute petals, and the clinandrium hood upturned, with the margin erose. Epidendrum excisum Lindl. has laterally flattened stems, an erect, lax-flowered paniculate inflorescence, the light yellowish-green flowers more or less tinged with copper."
