" Epidendrum deltogastropodium belongs to the GROUP Diothonea SUBGROUP Gastropodium, characterized by the branching habit, linear-lanceolate to lanceolate, bilobed leaves, arching-nutant, racemose inflorescence, membranaceous or rarely fleshy flowers, the lip entire to 3-lobed, with an erose margin, ecallose, with or without 1 to 10 thin, smooth to erose keels, the column united to the lip from totally to obliquely to free, the subgroup has small, usually brightly colored flowers, the column ending in fleshy-thickened, lobes. The new species has small, acute floral segments, the sepals .152 to .232" [3.8 to 5.8 mm] long and the triangular-subcordiform lip is truncate at the base and provided with a prominent, "V" shaped, triangular cushion. It is similar to Epidendrum gastropodium which has .24 to .3" [6 to 7.5 mm] long sepals, and the deeply cordate lip has a transverse cushion ending in three short keels. Epidendrum eugenii Schltr. has .212 to .228" [5.3 to 5.7 mm] long sepals and the lip has no cushion but three long, parallel, low keels. Epidendrum melanogastropodium Hágsater & Dodson has wide, rounded floral segments, the sepals .22 to .26" [5.5 to 6.5 mm] long and the lip provided with a transversely elliptic, massive, truncate cushion. Epidendrum mesogastropodium Hágsater & Dodson has acute floral segments, the sepals .2 to .224" [5.0 to 5.6 mm] long, and the cordate lip provided with a fleshy, truncate, transversely elliptic cushion."
