"Epidendrum erica-moroniae belongs to the GROUP Epidendropsis SUBGROUP Gracillimum characterized by the sympodial, caespitose, relatively small plants with non-thickened stems, long, paniculate inflorescence, delicate small flowers, and long, narrow, sub-coriaceous leaves. The species is recognized by the relatively tall plants, 8 to 12" [20 to 30 cm] tall, linear, wide leaves 1.6 to 3.2" x .08 to .2"" [3.5 to 8.0 x 0.2 to 0.5 cm], densely many-flowered inflorescence, with racemes .6 to 1.4" [1.5 to 3.5 cm] long, with up to 17 flowers per raceme, flowers greenish brown turning purple-pink, sepals spreading, .184 to .2" [4.6 to 5.0 mm] long, spreading, petals linear, and the ovary forming a elongate vesicle, and the lip entire. Epidendrum gracillimum has plants to 6 to 8" [15 to 20 cm] tall, leaves linear-lanceolate, 1.8 to 2.6" x .08 to .12" [4.5 to 6.5 x 0.2 to 0.3 cm], a laxly few-flowered inflorescence racemes .32 to .6" [0.8 to 1.5 cm] long, with 3 t0 5 flowers, petals filiform, and the lip clearly 3-lobed, the mid-lobe itself bilobulate, short and wide. Epidendrum schlimii Rchb.f. has plants with shorter, narrower leaves, .4 to 1.6{2.2"] x .08 to .12" [1 to 4[5.5] x 0.2 to 0.3 cm], inflorescence laxly few-flowered, racemes 2-flowered up to 2" [5 cm] long, dorsal sepals strongly reflexed, parallel to the ovary, and petals filiform. Epidendrum rolfeanum F.Lehm. & Kraenzl. has plants 4.8 to 7.2" [12 to 18 cm] tall, leaves acicular, .16 to .44" x .04 to .08" [4 to 11 x 0.1 to 0.2 mm], inflorescence composed of racemes .2 to .6" [0.5 to 1.5 cm] long, with 3 to 6 flowers, the flowers purple-brown, the disc of the lip greenish yellow, dorsal sepal strongly reflexed, and petals filiform. Epidendrum cryptorhachis Hágsater has by far the tallest plants in the group, to 17.2" [43 cm] tall, leaves 1.12 to 4" x .16 to .32" [2.8 to 10 x 0.4 to 0.8 cm], linear-lanceolate, a densely many-flowered inflorescence with multiple racemes parallel to the rachis, with up to 14 flowers per raceme, lip 3-lobed, petals narrowly spatulate. Epidendrum physophorum Schltr. has small plants, 4 to 6" [10 to 15 cm] tall, leaves 1.4 to 2.4" x .06 to .012" [3.5 to 6.0 x 0.15 to 0.3 cm], racemes of the inflorescence with 5 to 6 flowers, dorsal sepal strongly reflexed and parallel to the ovary, petals filiform and the ovary with a very prominent inflated vesicle."
