Common Name The Rolled Lip Epidendrum
Flower Size to 1" [to 2.5 cm]
This small sized, cool growing epiphytic species is found in Costa Rica and Panama at elevations of 1000 to 1200 meters on the Pacific slope with cylindric pseudobulbs carrying a single, apical, erect, ligulate, acute, coriaceous leaf that blooms in the late winter and spring on a terminal, erect to gracefully arching, short to 6" [to 15 cm] overall, rachis to 3.6 to 4.4" [9 to 11 cm] long, laxly several flowered inflorescence arising on a new growth with fragrant, long-lived flowers.
"Epidendrum volutum belongs to the GROUP Coilostylis which is characterized by the sympodial, caespitose plants, the stems forming a fusiform, heteroblastic pseudobulb, with an apical, racemose, distichous inflorescence, the peduncle covered by large bracts, and flowers large, star-shaped, with long, narrow sepals and petals. The species is recognized by the thickened stem with 2 to 3 apical, narrowly elliptic-lanceolate leaves 2.4 to 8.04" [6 to 21 cm] long, the inflorescence produced from the immature stem, with 4 to 12 small, green to greenish brown flowers, sepals .56 to .72" [14 18 mm] long, the suborbicular-cordiform, obscurely lobed lip. Epidendrum purpurascens Focke (syn. Coilostylis clavatum) has larger flowers, sepals .6 to 1" [15 to 25 mm] long, and the lip clearly 3-lobed, with the midlobe widened towards the middle. Epidendrum oerstedii Rchb.f. also flowers from the immature pseudobulb, but has 1 to 2, ovate-elliptic, thickly coriaceous leaves, 2 to 5 large flowers, sepals 1.6 to 2-6" [40 to 65 mm] long, the lip deeply 3-lobed, the margins entire. Epidendrum ciliare L. is similar to the latter, but flowers from the immature pseudobulbs, and the outer margin of the lateral lobes is deeply fimbriate." Hagsater etal 2008
