Description

Epidendrum cylindraceum stems are completely covered with tubular sheathes which bear one to two ovate-oblong leaves near the apex.[2] The peduncle is clothed in two or three elongate herbaceous sheathes, arranged in a fan. The inflorescence is a dense raceme, up to 15 cm long by 5 cm in diameter. The rather small, non-resupinate, mostly white flowers have obovate acute sepals nearly 1 cm long that are rough on the outside, and linear petals. The deeply trilobate lip is adnate to the column to its apex: the small lateral lobes are sickle-shaped, with slight fringing on the proximal edge, and the much larger central lobe is kidney-shaped at its apex.
