Flower Size .4" [1 cm]

Found in northwestern Venezuela, Colombia, Ecuador and Peru in cloud forests on rocky slopes at elevations around 2400 to 2900 meters as a medium sized, cold growing epiphyte or terrestrial with suberect, basally sub terete grading laterally lightly compressed above leafy towards the apex stems enveloped by old gray leafless sheaths or newer green, leaf bearing sheaths and carrying linear-lanceolate, acute, basally clasping leaveds that blooms in the later spring on a terminal, erect peduncle to 10" [25 cm] long, then pendent to arching rachis, to 4.8" [12 cm] long, moderately compressed, densely, simultaneously many flowered inflorescence with pale green, very narrow, about as long as the ovary floral bracts and carrying pale green to greenish cream flowers.

"Epidendrum anthoceros belongs to the GROUP Alpicolum SUBGROUP Alpicolum identified by the caespitose habit, few-Ieaved stems, long, parallel sided spathes, racemose inflorescence, fleshy flowers oriented in the same sense as the rachis, ·thus producing a fox-tail appearance. The species is recognized by the larger flowers, the sepals .4 to .44" [10 to 11 mm] long, the lateral lobes rounded and denticulate, but without any prominent horn, and the peduncle of the inflorescence elongate, longer than the apical leaf which is acuminate. Epidendrum anthoceroides has sepals .24 to .36" [6 to 9 mm] long, the lateral lobes of the lip divided into two, the posterior lobe erose and the front lobe forming a large crooked horn. Epidendrum oblongialpicolum Hágsater & Dodson has oblong, rounded to bilobed leaves, very wide compressed stems (up to .64" [16 mm]), lateral lobes of the lip reniform, proportionately small and erose, without any prominent horn-like lobe."
