Common Name or Meaning The Corymb Forming Epidendrum

Flower Size .8" [2 cm]

Found in Peru in wet montane forests at elevations around 1600 to 1700 meters as a small to medium sized, cool growing epiphyte and occasional terrestrial with a sub-erect, leafy stem enveloped completely by imbricating, tubular, distichous sheaths and carrying oblong-elliptic to elliptic, basally clasping, acute, dark green, subcoriaceous leaves that blooms in the spring on a terminal, erect, very densely, successively many flowered, racemose inflorescence holding the flowers in a corymb and having successive, subsequent basal branches on the inflorescence forming flowers.

"E. corymbosum belongs to the GROUP Secundum SUBGROUP Elongatum , recognized by the caespitose habit, numerous oblong leaves, usually elongate peduncle of the inflorescence, with a raceme of nonresupinate flowers, complicated callus and granular caudicles of the pollinia. The species is similar to Epidendrum brachycorymbosum, in all ways other than the its short peduncle. At first sight, Epidendrum brachycorymbosum, because the peduncle has bracts, the appearance of the plant seems to indicate a member of the GROUP Alpicolum, but the flowers immediately indicate otherwise. The flowers are typically a member of the SUBGROUP Elongatum , with the complicated callus, fringed lip and caudides of the pollinia formed by long pollen tetrads reminiscent of a stack of roof shingles." adapted from plate 714 Hagsater etal 2004
