"Epidendrum trullatum belongs to the GROUP Andean SUBGROUP Soratae , characterized by the branching habit, superposed stems, infundibuliform, rugose leaf-sheaths, lanceolate-oblong, aristate leaves, no spathe, and a compact, racemose, nutant inflorescence on a short peduncle. The new species can be recognized by the .68 to .72" x .14 to .16" [17 to 18 x 3.5 to 4.0 mm] long sepals, lanceolate-linear petals, trullate to angular-ovate lip .44 to .6" x .4 to .46" [11 to 15 x 10.0 to 11.5 mm], acuminate to rounded at the apex.
