"Epidendrum congestum belongs to the GROUP Nanodes , characterized by the caespitose to creeping, sympodial plants, the short stems completely covered by the base of the non-articulate, fleshy, imbricating leaves anf the sessile, few-flowered inflorescence. The species is recognized by the 2 to 3 green flowers, sometimes tinged with reddish purple, the emerald-green, cordiform lip w ith the margin entire, the clinandrlum hood somewhat erose, and the apex of the anther truncate and dentate. Epidendrum congestoides Ames & C.Schweinf. has a two-flowered inflorescence, greenish bronze or reddish-purple tinted flowers, the lip reniform-semiorbicular, with the base deeply cordate, and the clinandrium hood fimbriate. Epidendrum schlechterianum Ames & C.Schweinf. has relatively long flowers, the sepals .68 to .8" [17 to 20 mm] long, and the lip cordate-reniform, with the margin irregularily dentate, the column .4 to .56" [10 to 14 mm] long with the anther elongate, and the clinandrium-hood with the margin deeply lacerate- dentate. Epidendrum serruliferum Schltr. has acute floral bracts, an acute triangular to ovate-triangular, shortly acuminate sepals, the margin of the petals ciliate, and the lip acuminate."
