Common Name Powell's Epidendrum [American Botanist in Central America 1900's]

Flower Size .16" [4 mm]

Found in Costa Rica and Panama in wet forests at elevations around 600 to 1200 meters as a small to just medium sized, warm to cool growing epiphyte with simple, cane-like, thin, terete basally, becoming compressed towards the foliose part, sinuous stem enveloped basally by tubular, non-foliar, scarious sheaths and carrying 3 to 6, along the apical 2/3 of the stem, distichous, articulate, suberect, linear-elliptic to linear-lanceolate, acute, minutely apiculate leaves that blooms in the summer and fall on a terminal, erect to slightly arching, 6" [15 cm] long overall, ancipitous, straight, densely many flowered inflorescence with the 2" [5 cm] long, laterally compressed peduncle almost completely hidden by the spathaceous bracts.

Many references cite E arcuiflorum as a synonym of E powellii but Epidendrum arcuiflorum Ames & C.Schweinf. 1930 differs in having a totally different, truncate, slightly arching column with a short, entire clinandrium-hood covering the anther, the lateral lobes of the lip are dolabriform and the mid-lobe ensiform and longer than the lateral lobes.
