Flower Size .6" [1.5 cm]

Found in Colombia and Ecuador in swamps, beach vegetation and lower wet montane forests at elevations of sealevel to 1250 meters as a small to just medium sized, hot to cool growing epiphyte with cane-like, laterally compressed, slightly fractifex stems enveloped completely by tubular leaf bearing sheaths carrying a few, linear, basally clasping, acute leaves that blooms at most any time of the year on a terminal, very short, erect, successive flowering inflorescence carrying 1 to 5, resupinate flowers.

Many references cite E dentiferum with light green flowers, linear petals and a sub-orbicular lip, as a synonym of E jejunum but it has white flowers with rhombic to oblanceolate petals and a cordiform lip.

"Epidendrum jejunum belongs to the GROUP Difforme which is characterized by the caespitose, sympodial plants, fleshy, pale green to glaucous leaves, apical inflorescence, sessile, rarely with a short peduncle, one-flowered to corymbose, without spathaceous bracts, fleshy, green to yellowish-green rarely white flowers. The species has lateraly compressed stems, elliptic to ligulate leaves, 1 to 5 succesive, white to white-greenish flowers, a cordiform lip, and deeply dentate clinandrium-hood. It is similar to Epidendrum dentiferum Ames & C.Schweinf., but that species has light green flowers, linear petals and a sub-orbicular lip. Epidendrum stellidifforme Hágsater & Dodson grows at elevations of 1200 to 1500 meters, has larger plants and flowers, lanceolate petals, and a sub-orbicular-cordiform lip with an acuminate apex. The species is, at first sight, superficially reminiscent of Epidendrum cuatrecasasii Garay; however that species has both apical and lateral inflorescences with successive bracts on the inflorescence tipical of the GROUP Alberti SUBGROUP Albertii , has a triquetrous ovary; the type only has an apical inflorescence which probably led the author to later reduced it to synonymy of E. jejunum."
