Found in Cunidinamarca department of Colombia from the Cordillera Oriental in northern Colombia, from the Páramo de Chingaza, at elevations around 2100 meters as a small to just medium sized, cold growing epiphyte with simple, cane-like, terete at the base, somewhat laterally compressed along the apical half, sub-erect stems covered at the base by tubular, non-foliar, scarious sheaths and carrying 3, sub-erect, alternate, articulate, coriaceous; basal sheath tubular, minutely striated, ancipitose, green, concolor; blade unequal in size (the basal leaf smaller), narrowly elliptic, apex acute, minutely apiculate, margin entire, spreading leaves that blooms in the spring on a terminal, arising through a narrowly elliptic, conduplicate in natural position, tubular at base, acute, amplexicaul, ochre-green, concolor, not sessile, but at the apex of peduncle spathe, peduncle.4 to 1" x .24" [1.0-2.5 x 0.6 cm], laterally compressed at the base, ancipitose at the apex, rachis laterally compressed, pale green, slightly sinuous, 8.4" [21 cm] long, apical, racemose or rarely paniculate, arching-nutant, laxly successively few, 6 to 7 flowered inflorescence so that 1-2 apical buds present when the lower flowers are totally developed, with much shorter than the ovary, linear-triangular, acuminate, embracing floral bracts and carrying resupinate, greenish yellow, concolor flowers with fragrance not registered.

"Epidendrum robinson-galindoi belongs to the GROUP Excisum SUBGROUP Friderici-guilielmi characterized by the sympodial habit, tall, unbranched stems, 3 to 5, unequal leaves, the sub-erect inflorescence with prominent spathe. The species is recognized by the pendant, epiphytic plants and nutant inflorescence longer than the stem and the apical leaf, to 14"[35 cm] long, laxly few-flowered, stems with 3 unequal leaves, 6 to 7 greenish yellow, concolor flowers, sinuous rachis, lateral sepals oblong-elliptic, petals linear-oblanceolate, acute, lip 3-lobed, midlobe rectangular-oblong, apex sub-acute, larger than the lateral lobes, disc 3-ribbed (the mid-rib elongate reaching the apex of the lip. Epidendrum trulliforme Garay & Dunsterv. has stems with 5 leaves of similar size, inflorescence as long as the apical leaf, with 3 green flowers tinged pink, lateral sepals narrowly oblanceolate, lip entire, base cuneate. Epidendrum carlos-uribei Hágsater & E.Santiago has a similar vegetative habit, but is lithophytic at 3500 meters in altitude, inflorescence has up to 10 orange brownish flowers with lip and column yellow, sepals oblong, petals narrowly oblanceolate, apex rounded, lip with mid-lobe cuneate and apex rounded, disc with a single wide rib. Epidendrum cocuyense Hágsater & E.Santiago, has 4 to 5 leaved stems, flowers green tinged purple; lip with orbicular lateral lobes, margin entire and midlobe oblong with apex truncate. Epidendrum sisgaënse Hágsater has larger, more robust plants, a racemose inflorescence with larger flowers, sepals .76 to .8" [19 to 20 mm] long, the dorsal sepals reflexed, nearly parallel to the ovary, lateral lobes of the lip semi-ovoid, and the mid-lobe rectangular-oblanceolate-spatulate, dorsally verrucose, petals linear-oblong, apex rounded, lip 3-lobed with lateral lobes orbicular, mid-lobe truncate at the apex, calli laminar."
