Common Name The Purple Underneath E porphyreum Epidendrum [refers to the dark purple undersides to the leaves the easiest distinguishing feature]

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.

This species is very close to E porphyreum with concolor green leaves but E hypoporphyreum is easily distinguished by the purple undersides of the leaf. It is also similar to E laeve [syn E ionodesme] but it 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, 8-9 mm long.
