"Epidendrum maderoi belongs to the GROUP Geminiflorum which is recognized by the erect, sympodial, scandent habit, several narrow leaves, a narrow, tubular, acute, spathaceous bract, several non-resupinate flowers on a short raceme, and an entire, bicallose lip. The species is recognized by the lanceolate, acuminate leaves, the erect inflorescence of 3 to 6 yellow flowers with the lip cream colored, sepals .6 to .69" [15.0 to 17.5 mm] long, narrowly elliptic with the margin revolute, petals oblanceolate, and the lip narrowly cordiform with the margin slightly erose. Epidendrum urraoënse Hágsater is vegetatively very similar, but has 3 to 4 pink flowers, the lip and column white, sepals .68 to .72" [17 to 18 mm] long, elliptic-obovate, petals ligulate-oblanceolate, and the lip cordiform-obpandurate. Epidendrum inornatum Schltr. has leaves 2.4 to 4.2" x .12 to .2" [6.0 to 10.5 x 0.3 to 0.5 cm], linear-oblong, up to 12 green flowers, sepals .2 to .24" [5 to 6 mm] long, and the lip .14 x .1" [3.5 x 2.5 mm]. *NOTE: In the illustration published under Nr. 188, in Mansfeld (1929), the margin of the lip is clearly undulate, but none of the images nor specimens seen show that, though the lip margin is somewhat erose."
