Common Name or Meaning Horned Anther Epidendrum

Flower Size .4" [1 cm]

Found on the Atlantic slope of Panama and the Pacific slopes of Colombia and Ecuador at elevations of sealevel to 650 meters as a miniature sized, hot to warm growing epiphyte with short, branching from the subapical internodes, cane-like stems carrying 5 to 10, all along the stem, articulate, ovate-elliptic, unequally bilobed, strongly carinate leaves that blooms in the late winter through late fall on a terminal, arising on any of the branches, racemose, distichous, shortly pedunculate, simultaneously 2 to 6 flowered inflorescence with amplexicual, imbricating, widely ovate to elliptic, obtuse, longer than the ovary floral bracts and carrying non-resupinate, yellowish green flowers.

The title to the drawing by Dodson above has the name spelled as E coronanthera which is incorrect it should be E cornanthera.

"Epidendrum cornanthera belongs to the GROUP Ramosum which is characterized by the monopodial, branching stems, the spike-like, distichous inflorescence, and the single callus, and the 1899 SUBGROUP Repens, which has strictly pendent plants, with small leaves less than 1” [2.5 cm] long. The species is recognized by the small, pendent plants, leaves distributed throughout the stems, strongly carinate, .4 to .8" [1 to 2 cm] long, the 2 to 6 flowered inflorescence, triangular lip and the ovary forming a vesicle behind the perianth, the column with a pair of incurved apical teeth, the anther two-horned and the sepals acute. It is very similar to E. exiguum Ames & C.Schweinf. which is found along the Atlantic slope in western Costa Rica at elevations of 650 to 900 meters and has shorter leaves, to .4" [1 cm] long, 2 to 3 flowers and acuminate lateral sepals. Epidendrum repens Cogn. and E. brachyrepens Hágsater are also pendent, but the plants are much longer, the inflorescence single-flowered, the column does not have apica l teeth and the anther lacks the apical horns. Epidendrum luckei Bock has longer stems, pale green flowers, ovate-elliptic leaves, calli three dentate, the middle longer than the lateral teeth." Hagsater etal 2007
