Common Name The False Nocturnum Epidendrum

Flower Size 2.4" [6 cm]

Found in northernmost Ecuador and possibly southern Colombia in coastal rainforests at elevations of 250 to 800 meters as a small to medium sized, hot to warm growing terrestrial on roadside slopes or as an epiphtye in tall trees in rainforests with simple, terete, straight stems carrying 6 to 8, elliptic to oblong, unequally bilobed apically, coriaceous, deep green, basally clasping leaves that blooms in the winter on a terminal, several over years from the same, successively single flowered inflorescence. Differs for E nocturnum by the terete, non-ancipitous stem with green leaves and smaller flowers with sepals and petals being 1.88" to 2.08" [4.7 to 5.2 cm] long as well as the capsule has a short pedicel and an apical beak.

"E pseudonocturnum is part of GROUP Nocturnum characterized by the simple stems carrying large star-shaped flowers usually with a 3-lobed lip. The general aspect of E. pseudonocturnum is that of E. nocturnum Jacq., but can be distinguished by the terete , non-ancipitous stems, the green leaves of 3.2 to 4.8 x .8 to 1.2" [8 to 12 x 2 to 3 cm], and the smaller flowers with sepals and petals 1.88 to 2.08" [47 to 52 mm] long. The capsule has a short pedicel and an apical beak, each only about .6" [15 mm] long, while in E. nocturnum the capsule has a pedicel about 2-4" [6 cm] long. Epidendrum buenaventurae Schltr., from the Colombian coast, has leaves to 6" x .6" [15 x 1.5 cm] and sepals 1.2 to 1.72" [30 to 43 mm] long. E. litense Hágsater & Dodson is much smaller in every sense, the leaves being .68 to 3.2" x .12 to .4" [1.7 to 8 x 0.3 to 0.95 cm] long." Hagsater etal 1993
