Common Name Degranville's Epidendrum [French Botanist in French Guiana and collector of type current]

Flower Size 1.6" [4 cm]

Found in French Guiana at elevations around 700 meters as a small sized, warm growing epiphyte with simple, cane-like, laterally compressed, ancipitous stems carrying 2 to 3, all along the apical 2/3's of the stem, unequal, basally smaller, coriaceous, alternate, elliptic to ovate-elliptic, unequally bilobed apically, dorsal keel, veins evident, margin entire leaves that blooms in the earlier winter on a terminal, sessile, racemose, successively single, several flowered inflorescence that reblooms over several years with a much shorter than the ovary, hidden within the foliar sheath, triangular, acute, amplexicaul floral bract and carrying resupinate, flowers with red brown tepals.

"Epidendrum degranvillei belongs to the GROUP Nocturnum which is characterized by the sympodial, caespitose plants, short, racemose or pluri-racemose inflorescence, without spathaceous bracts, usually large, star-shaped flowers, with similar sepals and petals, and the SUBGROUP Nocturnum which has cane-like stems, non-thickened towards the middle, and usually successive flowers; the flowers are mostly indistinguishable in shape. The species can be recognized by short plants, ancipitose stems, with 2 to 3 elliptic to ovate-elliptic leaves, length/width: 2:1; ovary twice as long as the sepals which are .192 to .196" [48-49 mm] long, sepals and petals red-brown, the lateral lobes of the lip narrowly semi-rhombic, the outer margin irregularly dentate beyond the middle, the rest entire, the column with an acute, triangular tooth on each side, and the clinandrium-hood with a prominent, sub-erect, triangular, acute extension in the middle. It is similar to Epidendrum anchinocturnum Hágsater, a species endemic to the Valle del Cauca in Colombia, but the flowers of that species are smaller, sepals 1.04 to 1.16" [26 to 29 mm] long, the margins of the lip all entire, column short, .52" [13 mm], without lateral teeth, and the clinandrium-hood is dentate. Other species of this group with a similar leaf length/width ratio have taller plants, longer ovaries and larger flowers, the margins of the lip entire and the clinandrium-hood erose to dentate, they include Epidendrum angustilobum Fawc. & Rendle (syn. Epidendrum latifolium (Lindl.) Garay & Sweet), Epidendrum carpophorum Barb. Rodr., Epidendrum macroophorum Hágsater & Dodson & Epidendrum tridens Poepp. & Endl.." Hagsater etal 2010
