Common Name The Octomeria-Like Epidendrum

Flower Size .4" [1 cm]

Found in Honduras, Nicaragua and Costa Rica on trees in open fields and in cloud forests at elevations of 600 to 1650 meters as a small to just medium sized, pendant, warm to cool growing epiphyte with distant, erect, cylindrical, slightly compressed canelike stems enveloped completely by scarious sheaths and carrying 1 to 2, apical, erect, linear-ligulate, coriaceous, glabrous, sessile leaves that blooms in the winter on a terminal, short, 4 to 7 flowered inflorescence enveloped by scarious, inflated sheaths,

The rhizomatous plants with roots that arise from the base of the stem, carrying 1 to 2, ligulate leaves at the apex, the short, abbreviated inflorescence, the elliptic floral bracts with a white flower and the strongly nerved sepals and petals and the triangular-cordate and acute lip distinguish this species from others.

"Epidendrum octomerioides belongs to the GROUP Polychlamys which is characterized by the successive lateral growths, few leaves aggregate towards the apex of the stems, the distichous, apical inflorescence with prominent, conduplicate, acute floral bracts, and the SUBGROUP Octomerioides which has slightly thickened stems, rigid, fleshy thickened, linear-oblong to linear-lanceolate leaves, the apex unequally bilobed. The species is recognized by the slightly thickened stems, 1 to 2, apical, linear-oblong or linear-lanceolate, suberect, very fleshy-thickened leaves, and the white to rarely greenish white flowers, the sepals .3 to .4" [7.5 to 10 mm] long, and the triangular-cordiform lip with two very small calli. Epidendrum neoporpax (Rchb.f.) Ames, from Cuba and Hispaniola has smaller plants, with 2 to 4, short, narrow leaves .64 to 3.4 x .16 to .48" [1.6 to 8.5 x 0.4 to 1.2 cm] white to greenish yellow flowers with sepals .24 to .28" [6 to 7 mm} long, the lip ovate-cordate and the ovary inflated without forming a vesicle."
