Flower Size .6" [1.5 cm]

Found in Colombia on the cordillera central at the Nevado de Tolima to the eastern cordillera near Cuenca Ecuador at elevations of 2900 to 3900 meters as a small to just large sized, cold growing monopodial, much branching, erect epiphyte with cane-like, terete, more or less straight, the main stem long and branching from the middle and upper internodes, secondary stems consisting of 3 to 11 internodes and those also producing new stems and carrying numerous, linear-lanceolate, acuminate, those on the main stem larger than the leaves on the branches that blooms in the late summer through earlier winter on an erect to nodding, terminal, flowering only once, densely, simultaneously 10 to 16 flowering inflorescence with lanceolate, acuminate, shorter than the ovary floral bracts and carrying pale yellow resupinate flowers.

"Epidendrum angustissimum belongs to the GROUP Andean SUBGROUP Cuniculatum , which is characterized by the monopodial, branching habit, adpressed leaf-sheaths, acute leaves, small flowers and 3-lobed lip. The species is recognized by the very narrow leaves, .16" [to 4 mm], the flowers distributed throughout the dense inflorescence, the 3-lobed lip, with semiobricular lateral lobes and serrulate margins, sepals .2 to .268" [5.0 to 6.7 mm] long. In central Ecuador it grows in the same reglon as Epidendrum tenuicaule Lindl. which has the same hablt, clearly wider leaves .14 to .4" [3.5 to 10 mm] wide, the arching small inflorescence with greenish yellow, simultaneous flowers, the lateral lobes of the lip dolabriform. Epidendrum cuniculatum Schltr. has a deep nectary, a larger clinandrium-hood with the margin sinuous, and very short, reniform, lateral lobes of the lip, with a sinuous margin. Epidendrum anthropophorum Rchb.f. is vegetatively similar but the flowers have rectangular lateral lobes of the lip and the midlobe itself bilobed, thus giving the flowers a hominid-like appearance."
