Flower Size .8" [2 cm]

Found in Honduras as a natural hybrid between E ciliare and E nocturnum in pine oak woods at elevations around 3200 meters as a miniature sized, cold growing epiphyte with thickened into a fusiform, hetroblastic pseudobulb enveloped by 3 to 4 papery sheaths and carrying 3 to 4, on an immature pseudobulb, a single to rarely 2 on a mature stem, aggregate towards the apex, coriaceous, articulate, narrowly elliptic-lanceolate, acute leaves that blooms in the late spring, summer and mid fall on a terminal, arising on an immature stem, pluriracemose, distichous, peduncle laterally compressed, enveloped by 2 to 3, oblong-triangular, acuminate bracts, rachis terete, thin, straight to slightly sinuous, simultaneously 3 to 4 flowered inflorescence with much shorter than the ovary, progressively shorter, oblong-triangular, acuminate floral bracts and carrying resupinate flowers with the tepals light green to yellowish green becoming yellower with age.

" Epidendrum x dorotheae 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 (but not spathaceous bracts), and the flowers large, star-shaped, with long, narrow sepals and petals and GROUP Nocturnum SUBGROUP Nocturnum. The species is recognized by the 5 to 12.2" [12.5 to 30.5 cm] long, fusiform pseudobulbs, flowering when immature, the ovary as long as the sepals 2.8 to 3.6" [70 to 90 mm], deeply 3-lobed lip, outer margin of the ovate lateral lobes serrulate to slightly fimbriate; a putative hybrid between E nocturnum and E ciliare two widely distributed species. Epidendrum nocturnum has cane-like, terete stems, 4 to 12 leaves distributed throughout the apical 2/3 of the stem, successive flowers produced one at a time, and slightly smaller, with the margins of the lip entire, the inflorescence is very short, without bracts on the peduncle. Epidendrum ciliare flowers from the mature fusiform pseudobulb, with 2 to 13 flowers, the outer margin of the lateral lobes of the lip deeply fimbriate. Epidendrum oerstedii Rchb.f. also 2 flowers from the immature growth, but the margins of the lip are entire, and the midlobe of the lip is widened in the middle." Hagsater etal 2008
