Flower Size .8" [2 cm]

Found in Antioquia and Valle de Cauca departments of Colombia on the Cordillera Occidental and on the western slope of the Cordillera Central in Antioquia in premontane tropical forest at elevations of 1500 to 2870 meters as a giant sized, cool to cold growing, caespitose epiphyte with simple, cane-like, terete, thin, straight stems carrying 5 to 10, all along the apical half of the stem, alternate, articulate, oblong-elliptic, short acuminate, subcoriaceous, underside tinged purple, margin entire leaves that blooms in the late winter through mid fall on a terminal, paniculate, erect, peduncle 4.2" [10.5 cm] long, thin, somewhat laterally compressed, straight, enveloped by 3 tubular, sscarious, acuminate, partly imbricating bracts, rachis with 3 to 5 short branches, successively few, 6 to 10" [15 to 25 cm] long overall, densely 40 to 70 flowered inflorescence with much shorter than the ovary, narrowly triangular, acuminate, amplexicaul floral bracts and carrying resupinate, softly fragrant, purple rose flowers with cream colored disc and calli.

"Epidendrum hypoporphyerum belongs to the GROUP Pseudepidendrum which is characterized by caespitose plants, cane-like stems, acute to acuminate leaves, usually apical inflorescence, the mostly filiform petals and the lip usually 3-lobed with 3 parallel fleshy keels, the apical lobe often bifurcate, the “bird-wing” type pollinia, at least the inner pair, and the SUBGROUP Porphyreum which has flowers colored reddish orange, deep purple or lilac-pink, the calli generally prominent, sometimes horn-like. The species is recognized by the oblong-elliptic leaves, ventrally tinged with purple; the purple-rose flowers with the disc of the lip cream-colored, sepals .44 to .64" [11 to 16 mm] long; the lateral lobes of the lip are trapezoid, somewhat falcate, the basal margin somewhat involute, the mid-lobe widely triangular, widely emarginate, margin entire, spreading, forming a pair of oblong, divergent lobes, the apices rounded. It is similar to Epidendrum porphyreum Lindley which has similar plants, but the leaves are somewhat wider .6 to 1.6" [1.5 to 4 cm], green and concolor; the lateral lobes of the lip are ovate-dolabriform, and the mid-lobe widely deltoid, divided into a pair of triangular lobes. Epidendrum leave Lindl. (syn.: Epidendrum ionodesme Schltr., Santiago & Hágsater 2010a has the lateral lobes of the lip dolabriform-trapezoid, the width of the lip equal in width between the lateral lobes and the mid-lobe, the mid-lobe is deeply emarginate at the apex and forms a pair of linear-oblong, divergent lobes, the column is short,.32 to .36" [ 8-9 mm] long."
