LATE LATE

Common Name The Nodding Epidendrum

Flower Size .6" [1.5 cm]

Found from southern Colombia to northwestern Venezuela, Ecuador, Peru and Bolivia in disturbed pastures on trees and shrubs and on embankments as a terrestrial at elevations around 3000 to 3300 meters as a large sized, cold growing epiphyte with a very branched stem enveloped completely by tubular, imbricating, leaf-bearing sheaths with the younger ones above attached to subcoriaceous, oblong, acute, obtuse and obliquely bilobed apically, articulate to the leaf sheaths below leaves that blooms in the fall on a short, terminal, 3" [7.5 cm] long, racemose inflorescence with a few to many simultaneously opening flowers.

"Epidendrum cernuum belongs to the GROUP Andean SUBGROUP Cernuum, characterized by the monopodial habit, cane-like stems with sub-apical branches which are considerably shorter than the main stem, coriaceous to sub-coriaceous leaves, apex bilobed, and fleshy flowers, the lip 3-lobed. The species is recognized by the generally oblong leaves, long, cylindrical, many flowered inflorescence with greenish yellow to yellowish brown, simultaneous flowers, the lateral sepals are prominently aristate, the lateral lobes of the lip obliquely ovate, somewhat smaller than the midlobe which is sub-rectangular, the apex truncate and minutely apiculate. Epidendrum pseudocernuum Carnevali & I.Ramírez is vegetatively very similar, but the inflorescence shorter, lax, few flowered, never cylindrical, and the column strongly arched; it is apparently endemic to the cordillera of Mérida, Venezuela. Epidendrum brevicernuum Hágsater & Dodson has shorter, lax, few-flowered inflorescences, greenish white to green flowers, the lateral lobes of the lip as large as the midlobe, and the apex of the midlobe emarginate, not apiculate. Epidendrum cleefii Hágsater & E.Santiago has a shorter inflorescence, 2.6 to 3.6" [6.5 to 9 cm] long, and the midlobe of the lip narrow, obtuse and not apiculate, much longer than the lateral lobes."
