Common Name The Bellow-Like Epidendrum

Flower Size .6" [1.5cm]

Found in Guatemala, Costa Rica and Panama at elevations of 1400 to 2100 meters as a small sized, cool to just cold growing epiphyte with simple, cane-like, basally terete, laterally compressed above, erect to prostrate, straight stems carrying 9 to 11, evenly distributed along the stem, alternate, articulate, lanceolate, long-acuminate, minutely apiculate, fleshy-succulent, gray-green above, purple tinged below, margin entire leaves that blooms in the fall on a terminal, racemose, producing more than one over time, flowering over several years, laterally compressed, with 5 to 8, tubular, acuminate bracts, straight to slightly sinuous, terete, laxly 3 to 12 per raceme, to 50 flowered overall inflorescence with shorter than the ovary, widely infundibular floral bracts and carrying nocturnally fragrant flowers scented of calcium hydrochloride.

" Epidendrum physodes belongs to the GROUP Physinga which is characterized by the generally small, caespitose plants, the inflorescence apical and racemose producing new racemes with time and thus pluriracemose, the successive flowers opening one at a time on an elongate peduncle with acuminate bracts, the lip entire and the ovary with a prominent vesicle. The species is recognized by the lanceolate, short-acuminate, gray-green, fleshy leaves, the lip transversely elliptic, somewhat concave, the calli prominent, rounded, the clinandrium-hood short, f1eshy, not surpassing the body of the column. Epidendrum polygonatum Lindl. from the Antilles is very similar but has smaller f1owers, sepals .14 to .2" [3.5 to 5 mm long] and the widely obovate lip has evident, high, f1eshy keels. Epidendrum macroclinium Hágsater has shorter.6 to 1.8" [1.5 to 4.5 cm long], ovate-lanceolate, obtuse to acute, gray-green, sometimes with the foliar veins thickened and very evident on the basal half of the upper side of the leaves, the obreniform lip, the short calli, placed far from the apex of the column, and a very prominent, fimbriate-dentate clinandrium-hood. Epidendrum prostratum (Lindl.) Cogn. is vegetatively very similar to the latter, but the sepals and petals are partly spreading, the base of the lip deeply cordate, with 3 prominent keels on the disc, and the clinandrium-hood deeply emarginate, the margin entire."
