" Epidendrum tripetalum belongs to the GROUP Pleuranthium , characterized by the caespitose habit, cane- like, elongate stems, several short, lateral inflorescence, and the SUBGROUP Phragmites which has non-branching stems, subsessile, 1 or 2 flowered inflorescences, the flowers green or yellowish green, the ovary somewhat inflated and nearly hidden by 3 to 4 tubular, imbricating bracts. The species is recognized by the stems with ovate-lanceolate, suberect leaves, a single flowered inflorescence, sepals triangular-lanceolate, subacuminate .4 [10 mm] long, linear-oblanceolate lip similar to the petals with a thin keel, and the elongate, semi-tubular clinandrium-hood much surpassing the body of the column. Epidendrum phragmites has spreading, ovate-elliptic to ovate-lanceolate leaves, the inflorescence generally two-flowered, and the lip ovate to rarely 3-lobed with a thick, very fleshy keel. Epidendrum leonii D.E. Benn. & Christenson has much shorter plants 11.2 to 14" [28 to 35 cm] tall, with ianceolate, acute, leaves, a 2-flowered inflorescence the lip clearly 3-lobed, the midlobe triangular, the clinandrium-hood elongate, strongly dentate."
