Common Name The Muricate Sepals Epidendrum

Flower Size .8" [2 cm]

Found in Costa Rica in primary and secondary forests at elevations around 2000 meters as a medium to giant sized, cool to cold growing epiphyte with simple, cane-like, laterally compressed, erect stems carrying numerous, all along the stem, alternate, oblong-elliptic, acuminate, margin entire leaves that blooms in the spring through summer on a terminal and lateral from the base of the apical leaves, racemose to compound racemose, short to 45 flowered inflorescence occuring successively over several years producing new inflorescence from the internodes of the peduncles, enveloped almost completely by a pair of partly imbricating, tubular sheaths and with half as long as the ovary, shorter towards the apex of the raceme, triangular, acuminate floral bracts and carrying successively opening, resupinate, yellow flowers.

"Epidendrum muricatisepalum is part of GROUP Anceps which is recognized by the simple stems, generally elongate, compound racemose inflorescence producing new successive racemes with time, fleshy flowers, filiform to narrowly spatulate petals, and SUBGROUP Polyanthum the which has elongate, not sub-corymbose racemes. The new species is recognized by the caespitose habit, pluriannual, pluriracemose inflorescence of small, fleshy flowers; the densely muricate-strigous ovary and dorsal surface of the sepals. It is dosely related to Epidendrum pergameneum which has the same habit induding the lateral inflorescences, but the flowers have glabrous, unornamented sepals and ovary, the sepals are .28" [7 mm] long and the lobes of tne lip twice as long as broad. Epidendrum myodes Rchb.f. has much smaller flowers." Hagsater etal 204
