Common Name The Chirripo Epidendrum [A national park in Costa Rica]

Flower Size .8" [2 cm]

Found in Costa Rica and western Panama in lower cloud forests at elevations of 3000 to 3200 meters as a small to medium szied, cold growing epiphyte with a branching cane-like, flexuous stem carrying many, all along the stem, elliptic-oblong, unequally bilobed apically leaves that blooms in the later summer on a terminal, arising from the main stems and branches, arcuate, mostly 2 flowered, filiform rachis, racemose inflorescence with a conduplicate, prominent, ovate floral bract and carrying simultaneous, non-fragrant, brownish green to greenish yellow flowers

Recognized by its short inflorescence with a filiform rachis carrying 2 flowers with a triangular lip with a cordate base, an apically arcuate column and ovary that almost forms a 90 degree angle.

" Epidendrum chirripoense belongs to the GROUP Ramosum characterized by the monopodial, branching stems, the spike-like, distichous inflorescence, and the single callus, and the SUBGROUP Rugosum which has a branching habit with few-flowered inflorescence from short, secondary stems, the leaf-sheaths rugose. The species is closely related to E. anoglossoides Ames & C. Schweinf., and both share the erect , branching habit, the raceme produced from the apex of short branches, and the zigzag rachis. However, E. chirripoense can be easily distinguished from E . anoglossoides by the filiform rachis and the short, 2-flowered inflorescence. The flowers are very similar to those of E. mixtum Schltr., a highland species from Mexico and Guatemala, and those of E. mixtoides Hágsater & Dodson, a lowland species from Ecuador, but the latter two have more flowers, terete stems, and plants considerably larger and stouter."
