Flower Size 1.6" [4 cm]

Found in Florida [extinct], Cuba, Vera Cruz & Chiapas states of Mexico, Belize, Guatemala, Honduras, Nicaragua, Costa Rica and Panama in tropical rainforests, always near water at elevations of sealevel to 1000 meters as a medium to giant sized, pendant and hot to warm growing epiphyte with an elongate, terete, sinuous, pendant, many branching, cane-like stem enveloped entirely by leaf-bearing sheaths each carrying, distichous, all along the stem, articulate, coriaceous, oblong, bilobed apically, basally clasping leaves that blooms in the spring and summer on a terminal, distichous, short, peduncle to .4" [1 cm] long, 1 to 2 flowered inflorescence arising from the tertiary branches, with 2 to 3 imbricate, conduplicate bracts

E acunae is part of the GROUP Ramosum SUBGROUP Mirabile characterized by the pendent plants, successive stems produced from a middle internode of the previous stem, without any evident main stem; the flowers white to purple and mostly very fragrant. The species is distinguished by the long, hanging, branching plants with fleshy-coriaceous leaves about 4" [10 cm] long, flowering from short branchlets; it produces usually two greenish - brown flowers back to back, the floral segments .52 to .76" [13 to 19 mm] long. It has been confused with Epidendrum paranaense Barb.Rodr. which has a many-flowered inflorescence. Epidendrum singuliflorum Schltr. has smaller leaves and flowers, and these are green or greenish-yellow. In Guatemala it has been known under the name E ramosum Jacq. var. lanceolatum Griseb. after Ames & Correll's (1952) treatment.
