Common Name The Bump Covered Epidendrum [refers to the colliculose mass in front of the calli on the lip]

Flower Size .6" [1.5 cm]

Found in Narino Colombia on the Galeras volcano at elevations around 3200 meters as a small sized, cold growing epiphyte with cane-like, branched, terete, thin, erect, main stem long, the apparently shorter branches arise from the apical internodes of the stem carrying 4, on the branches, unequal, on the upper half of the stem, narrowly lanceolate, acute apically leaves that blooms in the winter on a terminal, occuring only once, on a mature stem, racemose, arching, nutant, .92" [2.3 cm] long including the .12" [3 mm] long thin, terete peduncle, and the terete, thin rachis, simultaneously to 10 flowered inflorescence with as long as the ovary, narrowly lanceolate, long acuminate, progressively shorter floral bracts and carrying resupinate, white flowers tinged with purple.

"Epidendrum colliculosum belongs to the GROUP Andean SUBGROUP Cuniculatum , which is characterized by the monopodial, branching habit, adpressed leaf-sheatns, acute leaves, and 3-lobed lip. The species is recognized by the bushy, branching, short plants, narrow leaves, mostly less than .2" [5 mm] wide at least on the branches, the arching small inflorescence with simultaneous flowers, white with a purple tinge, the lateral lobes of the lip well developed, dolabriform, an amorphous, colliculose mass in front of and between the calli, the whole margin of the lip strongly erose-fimbriate and a short nectary. It is very similar to Epidendrum tenuicaule which has greenish yellow flowers, glabrous sepals and the midlobe of the lip has an entire margin and three low keels in front the callus. Epidendrum cuniculatum Schltr. has a deeper nectary, penetrating more than half the ovary, a larger, funnel-shaped clinandrium with the margin sinuous, and very short, reniform, lateral lobes of the lip, with a sinuous margln. It grows in the same region as Epidendrum angustissimum Lindl. (syn. Epidendrum chortophyllum Schltr.) which forms a more open bush, and has linear-lanceolate, acuminate leaves to .14" [3.5 mm] wide, the rachis of the inflorescence longer, to 2.12" [5.3 cm] long and the lateral lobes of the lip semi-orbicular."
