Common Name The Glumeaceous Epidendrum [refers to the large floral bracts]

Flower Size .32" [8 mm]

Found in Honduras, Nicaragua and Costa Rica in wet montane forests at elevations of 1000 to 1800 meters as a small sized, cool growing epiphyte with a monopodial, branching, laterally compressed, flexuous, branching at mid stem, branches shorter than main stem carrying numerous on the main stem, 3 to 6 on the branching stems, papiraceous, minutely rugose and striated, narrowly ovate-elliptic, unequally bilobed apically, coriaceous, carinate leaves that blooms in the later summer through mid spring on an apical, from any of the stems, peduncle short, rachis to 1.6" [to 4 cm] long, distichous, fractiflex, several flowered inflorescence with a single basal, oblong-triangular, conduplicate bract and very prominent, elliptic, conduplicate, distichously arranged floral bracts leaving the rachis exposed and carrying greenish flowers that have the lip always facing the rachis.

"Epidendrum glumarum belangs to the GROUP Ramosum which is characterized by the submonopodial, much branched stems, apical racemose inflorescence and distichous flowers; and SUBGROUP Ramosum which has an erect primary stem and many smaller branches, several flowers on a zigzag rachis, the floral bracts usually covering more than the ovary. The species has laterally compressed stems, leaves narrowly ovate-elliptic, .24 to .8" [6 to 20 mm] wide, the apex unequally bilobed, 6 to 12 green flowers, the lip cordiform, rounded emarginate, and the callus tridentate. It is similar to E. pseudoramosum Schltr. which has terete stems, narrow, oblong leaves, .4" [10 mm] wide, 2 to 5 flowers with the lip trrangular-ovate. Epidendrum ramosum Jacq. has terete stems, narrow, strap-like leaves, green to yellowish green flowers, acute segments and a triangular lip. Epidendrum mixtum Schltr. is similar to the latter but has larger white flowers, and larger leaves." Hagsater etal 2007
