Common Name The Cylindrical Epidendrum [refers to the inflorescence shape]

Flower Size .4" [1 cm]

Found in Colombia, Ecuador and Peru in seasonally dry, montane cloud forests at elevations around 2000 to 3200 meters as a medium sized, cold growing epiphyte with a creeping rhizome, giving rise to erect, cane-like, branching stems enveloped by flattened, vaginate sheaths and carrying 1 to 2 per branch, apical, lanceolate to lanceolate-oblong, acute, clasping at the rounded base, erect-spreading leaves that blooms in the spring to summer on a terminal, erect, 13.6" [34 cm] long, rather dense, many flowered, inflorescence mostly enveloped by 2 to 3, close, equitant, imbricating, elongate spathes.

"Epidendrum cylindraceum belongs to the GROUP Cylindraceum characterized by the sympodial habit, narrow spathaceous bracts with parallel sides, an erect racemose inflorescence with non-resupinate flowers and a generally reduced, fleshy lip. This species can be recognized by its short and wide leaves, 2.4 to 4" x 1 to 1.4! [6 to 10 x 2.5 to 3.5 cm], short, compact, cylindrical raceme, the flowers distributed along the apical half of the inflorescence, sepals and petals .4 to .48" [10 to 12 mm] long, verrucose ovary, lateral lobes and midlobe of the lip with a crenulate margin, apex of midlobe bilobed. It is very similar to Epidendrum lřjtnantii Hágsater & Dodson, but that species has narrower leaves .72 to .8" [1.8 to 2.0 cm] wide, an unornamented, .48 to .6" [12 to 15 mm] long ovary, and the midlobe of the lip 3-lobed. Epidendrum parvilabre Lindl. from southern Ecuador and Peru has unornamented sepals and an unornamented, .28 to .4" [7 to 10 mm]* long ovary, and the midlobe of the lip erose. Epidendrum diphyllum Schltr., has narrower leaves 2.8 to 4.4" x .92 to 1.12" [7 to 11 x 2.3 to 2.8 cm], sepals dorsally spiculate, petals minutely and irregularly crenulate, smooth, long ovary .92 to 1.08" [23 to 27 mm] long, lateral lobes of the lip falcate-ligulate, acute, the margin crenulate, isthmus of the midlobe oblong, bilobed midlobe, the lobes long an narrow, and the apical margin crenulate-dentate."
