''Epidendrum ramosum'' is a neotropical species of reed-stemmed ''Epidendrum'' orchid which grows both epiphytically and terrestrially at altitudes near 1 km. == Description == ''E. ramosum'' stems do not swell into pseudobulbs, are highly branched, and are covered with close, tubular sheathes, the upper ones bearing longish leaves which are rounded at the apex.〔H. G. Reichenbach "Orchides" item 252, "EPIDENDRUM SELLOWII" in C. Müller, Ed. ''Walpers Annales Botanices Systematicae'' 6(1861)383. Berlin.〕 The short, scaly, apical peduncle bears a raceme with large, alternate floral bracts which nearly cover the long pedicellate ovaries of the few green-yellow flowers.〔C. Dodson & R. Vásquez "EPIDENDRUM RAMOSUM Jacq." Plate 0228 of ''Icones Plantrum Tropicarum, Series II Orchids of Bolivia'' Missouri Botanical Garden, St. Louis. 1989〕 The sepals are oblong-acute, 5–6 mm long and 2 mm wide; the petals are narrower. The cordate acute lip is adnate to the column to its apex, has no lateral lobes, and bears a callus consisting of two keel-like ridges near the column apex. The four pollinia are white.
