Found in Costa Rica and Panama at elevations of 1900 to 2700 meters as a miniature to small sized, cold growing epiphtye with a cane-like, thin, branching above stem carrying to 10, all along the main stem, 3 to 4 each on the branches, a single leaf on the flowering branches, each blade subcoriaceous, smooth, dorsally carinate, oblong-elliptic to linear, unequally bilobed apically leaves that blooms in the later summer though mid winter on a terminal, racemose, distichous, subsessile, 1 to rarely 2 flowered inflorescence with longer than the ovary, infundibuliform, verrucose, acute floral bracts and carrying resupinate, creamy white flowers with the apex of almost all parts tinged purple.

"Epidendrum cordiforme C. Schweinf., belongs to the GROUP Ramosum which is characterized by the monopodial, branching stems, the spike-like, distichous inflorescence, and the single callus, and the SUBGROUP Rugosum which has branching habit with few-flowered inflorescences from short, secondary stems, and the leaf- sheaths rugose. The species can be recognized by the small, tree like habit, its thin, terete stems, .48" [1.2 mm] thick flowers 1 or rarely 2, cream colored tinged with purple, the lip semiorbicular-cordiform and apiculate. It is very similar to Epidendrum elcimeyae Hágsater & Carda-Cruz from lower altitudes around 1350 m, which has ancipitose stems, 2 to 3 yellowish-green flowers, sepals narrowly lanceolate, 3-veined, petals narrowly oblong, 3-veined, and the lip triangular-cordate with a tridentate callus. Epidendrum microcardium Schltr. has 12" [30 cm] tall plants, terete stems, 5 to 10 small flowers, and sepals and petals linear, 3-veined, .16" [4 mm long. Epidendrum microdendron Rchb.f. has ancipitose stems, longer leaves and a 3-lobed lip." Hagsater etal 2007
