"Epidendrum carlos-uribei is closely related to the GROUP Excisum SUBGROUP Friderici-guilielmii, recognized by the tall, unbranched stems, 3 to 5 unequal leaves, the sub-erect inflorescence with prominent spathe. The species is recognized by the smaller plants, to 16" [40 cm] tall, brown-orange flowers with the lip and base of the petals yellow, sepals .68 to .84" [17 to 21 mm] long, margin revolute, petals with hyaline, erose margin, lip with a short fleshy mid-rib in between the calli, margin of the lip erose, lateral lobes sub-quadrate, the upper corner rounded, mid-lobe cuneate. It has been confused with Epidendrum sisgaënse which has much larger, robust plants, rhizome creeping, stems to 32 to 40" [80 to 100 cm] tall, flowers greenish brown with the lip red, lustrous, the lip has 3 thin ribs on the disc, margin is entire, lateral lobes are semi-ovate, and the mid-lobe rectangular. Epidendrum cocuyense Hágsater & E.Santiago is vegetatively very similar, but the flowers are green tinged with purple, sepals .6 to .64" [15 to 16 mm] long, lip with a long mid-rib that reaches the apical sinus, lateral lobes are orbicular, margin entire, and the mid-lobe oblong. Epidendrum trulliforme Garay & Dunst. has green flowers tinged pink, sepals .64" [16 mm] long, the inflorescence is subtended by two spathes that cover the peduncle completely, lip entire, trulliform, base cuneate and the apex acute, with two prominent horn-like calli."
