"Epidendrum llactapataense D.E.Benn. & Christenson 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 similar-sized plants ca. 5.2" [13 cm] tall but the inflorescence is paniculate, 2 to 2.4" [5 to 6 cm] long, with 10 to 12 concolor, ochre-yellow flowers, the sepals .24" [6 mm] long. Epidendrum joaquin-ortizii has small plants 5.2" [13 cm] tall, short, racemose, few-flowered inflorescence, the white flowers with the disc of the lip bright orange-yellow and fleshy thickened with multiple ribs, sepals .4 to .44" [10 to 11 mm] long. Epidendrum gracillimum Rchb.f. has larger plants to 8" [20 cm] tall, paniculate inflorescence, smaller flowers, sepals .2 to .252" [5 to 6.3 mm] long, and the lip with a single thickened mid-rib. Epidendrum erica-moroniae Hágsater & E.Santiago has much larger plants, 8 to 12" [20 to 30 cm] tall, a large paniculate inflorescence, 4 to 8.04" [10 to 21 cm] long, densely many-flowered, the flowers greenish brown, sepals .184 to .2" [4.6 to 5.0 mm] long, and the lip with 3 narrow, thin, parallel ribs. Epidendrum schlimii Rchb.f. is a delicate plant, paniculate inflorescences with 2-flowered racemes, the flowers pale red to purple-brown, lip entire, widely cordiform, and with a single, narrow mid-rib.
