Flower Size .24” [6 mm]

Found in Ecuador and Peru on the eastern slope of the Andes at elevations of 800 to 2800 meters as a medium sized, cool to cold growing, caespitose epiphyte with simple, cane-like, slightly laterally compressed stems carrying 8 to 17, all along the apical half of the stem, erect, alternate, articulate, linear, acuminate, margin entire leaves that blooms in the spring on a terminal, somewhat paniculate, peduncle thin, 1.8 to 2.8” [4.5 to 7 cm] long, with a median, prominent, tubular, conduplicate bract, rachis with 1 to 4 short branches, each 1.6 to 6” [4 to 15 cm] long, 4 to 8” [10 to 20 cm] long overall, lax, successively 18 to 70 flowered inflorescence with much shorter than to as long as the ovary, narrowly triangular, acuminate, amplexicaul floral bracts and carrying resupinate green flowers with the lip and the apex of the column white, often with a ring of purple dots surrounding the disc.

"Epidendrum poeppigii belongs to the GROUP Pseudepidendrum is characterized by caespitose plants, cane-like stems, acute to acuminate leaves, apical inflorescence, lacking a spathaceous bract, the petals filiform and the lip usually 3-lobed, with 3 parallel fleshy keels, the apical lobe often bifurcate, and the pollinia “bird-wing” type and SUBGROUP Paniculatum which has bicolor flowers, generally green with the lip and apex of the column white, the disc sometimes marked with purple to red. The species is recognized by the small plants to 27.2" [68 cm] tall, thin stems and narrow, linear, long acuminate leaves; the successive flowers have .2" [5 mm] long, strongly reflexed sepals, the lip bicallose the column short and thick, .12" [3 mm] long. Epidendrum yungasense Rolfe has somewhat smaller plants ca. 16" [40 cm] tall, but the arching-pendent stems producing keikies, the leaves oblong-lanceolate, acute, simultaneous flowers and the column thin, .2 to .24" [5 to 6 mm] long. Epidendrum parviflorum Ruiz & Pavón has narrowly lanceolate, acute leaves, simultaneous flowers, spreading sepals, and the lip with a single callus and lateral and apical lobes rounded. Epidendrum patulipetalum Schltr. has small plants, (ca. 14" [35 cm] tall with linear-lanceolate, short leaves 2 to 2.8" [5 to 7 cm] long, partly spreading, sepals .2" [5 mm] long, and the lip partly embracing the column in natural position, bicallose, with prominent, thin calli."
