Common Name The Beautiful Epidendrum

Flower Size 1.2" [3 cm]

Found only in western Colombia at elevations around 1600 meters as a large to giant sized, cool growing terrestrial with erect, simple, reed-like, terete stems enveloped completely by leaf bearing sheaths and carrying all along the stem, narrowly elliptic, subacute, entire, smooth leaves that blooms in the spring on a terminal, arising on a mature stem, occuring ,more than once over the years, racemose, arcuate, 8.8 to 16" [22 to 45 cm] long, successively few, several to many [12 to 24] flowered inflorescence carrying resupinate, fleshy flowers.

"Epidendrum oraion is part of the GROUP Cristatum SUBGROUP Cnemidophorum recognized by the long peduncle of the inflorescence covered by long, imbricating, conduplicate bracts, the successive raceme with the first flowers opening when the apical buds are just developing, and the fuchsia flowers with the lip white with fuchsia margins and with two elongate, white calli with deep fuchsia markings at their apices. This species closely resembles the Costa Rican E. pfavii Rolfe, which can be distinguished by the triangular-dolabriform basal lobes of the lip, which are about as wide as long, and the apical lobes only slightly divergent. Epidendrum quinquepartitum Schltr., from eastern Bolivia, has similar habit and flower color to E . oraion, but the lip is asymmetrically 5-lobed." Hagsater etal 1993
