Common Name or Meaning The Circular Callus Epidendrum [refers to the callus of the lip]

Flower Size .6" [1.5 cm]

Found in northern Peru in podocarpus forests at elevations around 2500 to 3000 meters as a small sized, cold growing epiphyte with branched, cane-like, arising from the basal internode of the previous stem, thin, laterally compressed, erect stems carrying 2 to 5, distributed in the apical 1/2 of the stem, articulate, oblong-elliptic, rounded apically leaves that blooms in the summer and earlier fall on a terminal, occuring only once, racemose, arching, 4 to 8" [10 to 20 cm] long, simultaneously 13 to 15 flowered inflorescence with 2 ancipitous, tubular, narrow, acute spathes and has longer to shorter than the ovary, narrowly triangular, acuminate floral bracts and carrying resupinate, pale brown red flowers.

" Epidendrum cyclotylosum belongs to the GROUP Alpicolum SUBGROUP Pergracile characterized by the caespitose habit, racemose inflorescence with narrow, parallel-sided spathaceous bracts, and flowers with a wide, rounded midlobe, and a large fleshy disc. The species is recognized by the small flowers with linear-oblanceolate petals and the lip 3-lobed, the lobes subequal in size, the margin entire, and a large, suborbicular, concave callus which occupies a large part of the surface of the lip, and is striated. Epidendrum rhodoides has somewhat larger leaves, larger flowers, sepals .4 to .44" [10 to 11 mm] long, wider narrowly obovate, 5-veined petals, the margin of the side lobes of the lip irregular-erose, and the lip with two long, parallel calli with the surface inbetween striated. Other species in the GROUP Alpicolum SUBGROUP Cyclotylosumsuch as Epidendrum sulcatum Ames, have the midlobe of the lip much longer than broad and two small calli at the base of the lip, sometimes with a short keel in the middle, but the disc of the lip is not thickened."
