"Epidendrum trullatigeminiflorum belongs to the GROUP Megagastrium SUBGROUP Geminiflorum, characterized by simple, sympodial, scandent, straggling habit, the semi-ovate spathe, the erect stems with 3 to 10 coriaceous leaves, and few non-resupinate flowers, and the lip with laminar calli, disc flat. The species is recognized by the vigorous growth, large orange flowers, the sepals .64 to .76" [17.0 to 19.0 mm] long, petals lanceolate, and the lip entire and trullate, somewhat narrowly cordate at the base, widest near the middle. It closely resembles Epidendrum geminiflorum Kunth which has green to greenish yellow flowers, where the lip clearly is widest at the base and it has two small sub-orbicular lateral lobes, the mid-lobe being widely triangular and sub-acute. Epidendrum cuencanum Schltr. has greenish white flowers, a cordiform lip, widest near the base, and the leaves widely elliptic to 1.72" [4.3 cm] wide. Epidendrum azuayense Hágsater & E.Santiago has smaller, orange colored flowers, the sepals .52 to .72" [13 to 18 mm] long and a widely cordiform lip. Epidendrum geminiochraceum Hágsater & E.Santiago also has orange flowers but these are larger, the sepals are .84 to .92" [21 to 23 mm] long, and the lip is clearly 3-lobed, the lateral lobes hemi-orbicular, and has two, very prominent spathes at the base of the inflorescence."
