Common Name Thread-Like Petal Epidendrum

Flower Size 1” [2.5 cm]

Found in southern Ecuador along the Cordillera de Condor at elevations of 1400 to 1600 meters as a small sized, cool growing epiphyte with simple, cane-like, ancipitose, straight stems carrying 8 to 11, all along the stem, unequal, gradually larger above, narrowly elliptic, acuminate, margin entire leaves that blooms in the fall on a terminal, without a spathe, erect, racemose, peduncle ancipitous, sides parallel, nude, with a subapical, elliptic, obtuse bract, successively single, few flowered inflorescence with as long as the ovary, elliptic, obtuse, conduplicate, imbricate floral bracts and carrying flowers with the sepals and petals olive green and the lip green.

"Epidendrum nematopetalum belongs to the 2001 GROUP Alberti SUBGROUP Physinga, distinguished by the caespitose habit, ancipitous stems, apical inflorescence, the apical peduncle ancipitous to the degree of being two-winged, the raceme subtended by a conduplicate bract at the apex of the peduncle, the floral bracts imbricate, flowers successive, one at a time, with a frequently prominent clinandrium. The species is recognized by the filiform petals, the cordiform lip and the prominent clinandrium somewhat arched with the margin minutely dentate. Epidendrum panamense Schltr. is similar but has fewer, larger leaves, a short stem, and an inflated ovary and the bracts much shorter than the ovary. Epidendrum dactyloclinium Hágsater & Dodson has a prominent three-lobed clinandrium, with the dorsal lobe deeply dentate, the lateral lobes oblong, acute, the lip triangular, the corners rounded, and the petals linear-oblanceolate."
