"Epidendrum vasquezii belongs to the GROUP Difforme which is characterized by the sympodial, caespitose, fleshy habit, green to glaucous leaves, the apical inflorescence lacking a spathaceous bract, sessile or with a very short peduncle, one-flowered to corymbose, and the green, greenish yellow or rarely white flowers. The new species has laterally compressed stems, 3 large flowers, with a bilobed lip, the lobes orbicular and apically notched, the disc with 3 keels and numerous, evident, radiating, thickened veins. It is similar to E. althausenii which is widely distributed in the Amazon basin, has rather short stems, a single, large flower, occasionally 2, rarely 3, the lip subquadrate when spread, with the emarginate midlobe short in relation the lateral lobes, the column straight or slightly arched, and the clinandrium-hood prominent, with the margin dentate-fimbriate. The Brazilian Epidendrum angustilobum has 2 to 4 large flowers, a 3-lobed lip 2 to 4 times wider than long, the lateral lobes semi-orbicular to sub-rectangular, the midlobe subquadrate to transversely rectangular, emarginate to bilobed, and the clinandrium-hood short, dentate. Epidendrum garciae Pabst is distinguished by the single flower, intensely fragrant during day-time, greenish whlte sepals and petals white, transversely oblong, 3-lobed lip with the lateral lobes semi-elliptic, midlobe shorter than the lateral lobes, emarginate, forming 2 semi-orbicular lobes, and the slightly arching column with a prominent, erose to dentate clinandrium-ñood. Of the larger Peruvian species, Epidendrum apaganum Mansf. and Epidendrum apaganoides O.E.Benn. & Christenson have 3-lobed lips with thickened veins, and Epidendrum pseudoapaganum Bennett & Christenson has an entire, reniform lip apparently without thickened veins or keels on the lip."
