Epidendrum cornutum Lindl. has 13 to 14 leaves, 2.8 to 5.4" x .32 to .56" [7.0 to 13.5 x 0.8 to 1.4 cm], narrowly oblong-lanceolate, apex acuminate, sepals .4 to .492" [10.0 to 12.3 mm] long, petals .368" [9.2 mm] long, only slightly shorter than the dorsal sepal, and mid-lobe of lip .18 x .044" [4.5 x 1.1 mm], narrowly triangular, acuminate. Epidendrum dolichocaulum Hágsater & A.G.Díaz has long stems, nearly 40" [100 cm] long, with 17 to 19 linear-lanceolate leaves to 3.6 to 6" x .32 to .48" [9 to 15 x 0.8 to 1.2 cm], a relatively short, laxly flowered inflorescence, large yellow flowers, long sepals .6 to .7" [15 to 20 mm] long, and a long straight lip, mid-lobe .336" x .08" [8.4 x 2 mm], with a relatively long mid-rib with a pair of shorter ribs in front of the calli.
