Found in Venezuela, Colombia, Ecuador, Peru along the upper Amazon Basin as well as the Pacific slope in Colombia and Ecuador at elevations of 600 to 2000 meters as a small to medium sized, warm to cool growing epiphyte with a monopodial, pendent, cane-like, newly arising from the intermediate nodes of the previous, terete, straight, tinged purple brown stem carrying a single persistent, to 3 on an immature growth, apical, pendent, articulate, dorsally green, ventrally purple red, linear-lanceolate, somewhat falcate, acuminate, margin entire leaf that blooms at most any time of the year on a terminal, racemose, short, peduncle subterete, with 2, tubular, acuminate, margin entire bracts, successively single, 2 to 3 flowered inflorescence with much shorter than the ovary, narrowly triangular, acute, amplexicaul floral bracts and carrying resupinate, fleshy, lustrous, generally creamy brown to rarely greenish, generally tinged with pink flowers with a greenish brown tinged with pink towards the apex column and a creamy white lip.
"Epidendrum filamentosum belongs to GROUP Filamentosum which is characterized by the thin, short pendent stems which originate successively from the previous stem, with a single, persistent, apical leaf (the juvenile main stem has several leaves), linear-lanceolate, acuminate; inflorescence apical, short, racemose, flowers successive, fleshy; lip 3-lobed, the margin of the lateral lobes dentate to ciliate; anther narrowly ovoid, long, surpassing the apex of the column. The species is recognized by the thin new stem produced from the middle of the previous stem, creamy brown flowers dorsally tinged pink, lanceolate sepals .36 to .6" [9 to 15 mm] long, filiform petals, and the short unguiculate lip with the margin of the lateral lobes dentate, low laminar calli, and the narrowly ovoid, elongate, apically bifid anther. Epidendrum ruizlarreanum D.E.Benn. & Christenson has white, concolor flowers, the entire lip with the margin fimbriate, high, laminar calli, and 3 narrow keels, the reniform anther is truncate. Epidendrum moronense Dodson & Hágsater has thickened, pseudobublous stems 1.6" [4 cm] long, greenish white, non-resupinate flowers, reflexed sepals and petals nearly as long as the ovary, and the lip is reniform with the margin lacerate."
