Found in northern Colombia on the southern slopes of the Sierra Nevada de Santa Marta at elevations of 1200 to 1725 meters as a medium sized, cool growing caespitose, terrestrial or epiphyte with cane-like, terete at the base, laterally compressed above, erect stems carrying 14, alternate, all along the apical 2/3'ds of the stem, sub-coriaceous, elliptic-lanceolate, acuminate, margin entire leaves that blooms in the later spring through later summer on a terminal, erect, without a spathe, occuring only once, peduncle, 1.52" [3.8 cm] long, straight, thin, without bracts, rachis paniculate, 5 branched, suberect, each 3.28" to 4.08" [8.2 to 10.2 cm] long, each branch with a basal, triangular, acuminate, margin entire bract, 7.6" [19 cm] long overall, simultaneously about 100 flowered inflorescence with much shorter than the ovary, narrowly triangular, acute floral bracts and carrying resupinate, membraneous, yellow green flowers with a white lip with out fragrance data.

"Epidendrum macroceras belongs to the GROUP Pseudepidendrum is characterized by caespitose plants, cane-like stems, acute to acuminate leaves, apical inflorescence, lacking a spathaceous bract, the petals filiform and the lip usually 3-lobed, with 3 parallel fleshy keels, the apical lobe often bifurcate, and the pollinia “bird-wing” type and SUBGROUP Paniculatum which has green and white flowers, often marked with purple on the disc of the lip and apex of the column. The species is recognized by very long, falcate, oblong, truncate apical lobes of the lip, and the basal lobes longer towards the apex than towards the base; the plants are intermediate in size, probably about 1 m tall; the color of the flowers is yellow green with the apex of the column and the lip white. Epidendrum angaritae Hágsater is somewhat similar, but the plants are shorter, the apical lobes acute and straight, not falcate, and the basal lobes of the lip longer at the base. Epidendrum cirrhochilum F.C.Lehm. & Kraenzl. has smaller flowers and very long, acuminate apical lobes of the lip. Epidendrum lilacinoides Hágsater & E.Santiago (syn: Epidendrum floribundum Kunth var lilacinum Rchb.f.) has purple flowers with a white blotch on the lip, sepals .52 to .56" [13 to 14 mm] long. Epidendrum floribundum Kunth has prominent floral bracts, .24 to .48" [6 to 12 mm] long; flowers with green sepals and petals, the lip and apical half of the column white, the lateral lobes dolabriform, and the mid-lobe formed by a pair of linear, non falcate, strongly divaricate lobes. Epidendrum paniculovenezolanum Hágsater & E.Santiago has much taller plants ca. 72" [1.8 meter], the leaves strongly tinged purple on the underside, sepals .52 to .56" [13 to 14 mm] long, ochre-green, dorsally tinged purple-brown, the petals green, and the lip white."
