Flower Size .4" [1 mm]

Found in the Serrania del Darien in Panama near the Colombian border in lower montane wet forests at elevations of 1500 to 1700 meters as a large sized, cool growing epiphyte with terete, erect, cane-like stems enveloped in the basal 1/3rd by tubular, leaf-bearing sheaths and carrying numerous, all along the apical 2/3rds of the stem, narrowly elliptic to lanceolate, acuminate leaves that blooms in the early winter on a terminal, arising on a mature stem, without a spathe, elongate, pluriracemose, newly flowering over several years, peduncle suberect, slightly arching, 2.8 to 3.2" [7 to 8 cm] long, much longer than the apical leaf, 14" [35 cm] long overall, rachis short, simultaneously 5 flowered inflorescence with triangular, acuminate, about half as long as the ovary floral bracts and carrying non-resupinate, green flowers with a white lip and the disc purple, the column cream colored, and without fragrance data.

"Epidendrum tacarcunense is a member of the 1999 GROUP Pseudepidendrum SUBGROUP Turialvae and closely related to the former, from which it can be distinguished by the large plants, the terete stems, the very long floral bracts .36 to .64" [9-16 mm], the flowers are green, with the lip white with a disk purple. Epidendrum turialvae from Nicaragua, Costa Rica and western Panama has the same general coloring but the floral bracts are short, .08 to .16" [2 to 4 mm] long, and the proportions of the lip are more equal in length to width. Other species of this group, E. rodrigoi Hágsater and E. vieirae Hágsater also have laterally compressed stems." Hagsater etal 1999
