Common Name or Meaning The Separated Lip Epidendrum [refers to the lip which is completely free from the Column]

Flower Size .12" [3mm]

Found in Ecuador and Peru along the eastern slope of the Andes in airy, wet, tropical evergreen forests at elevations of 600 to 2000 meters as a small to just medium sized, warm to cool growing epiphyte with an erect, cane-like, terete stem carrying, 2 to 4, on the upper portion of the stem, narrowly lanceolate-elliptic, acute leaves that blooms in the winter on a terminal, arcuate, racemose, 12 to 18 simultaneously opening inflorescence carrying resupinate, apple green flowers.

"The arching inflorescence with 12 to 18 simultaneous flowers, lanceolate-elliptic lip completely free from the column, lanceolate sepals, linear, acute petals, and the very large stigmatic cavity, occupying nearly the whole ventral surface of the column, make this species unique. The entirely free lip of this species is the only exception known to us in what is otherwise a constant character in Epidendrum, i.e., the partial adnation of the lip and column, but all other floral parts are quite typical of the genus. The species belongs to the GROUP Alpicoloum SUBGROUP Dialychilum , in which the lip generally is united to the column and 3-lobed." Hagsater etal 1993

Since Hagsater wrote the above -- Epidendrum dialyrhombicum is a small-sized plant closely related to E dialychilum with narrow grass-like leaves up to 2.8 x .16" [7 x 0.4 cm]; the short, erect, compact inflorescence with deep green and white, globular and setaceous, nonresupinate flowers, the sepals .12 to .16" [3 to 4 mm] long, the lip free from the column, rhombic with a long, narrow claw perpendicular to the base of the lip and then turning up and parallel to it, the column with the rostellum projecting beyond the rest of the body. Epidendrum pterastele Hágsater & Dodson also has a free lip, but narrowly elliptic, and the column has a prominent clinandrium which gives it a winged appearance." Hagsater etal 2001
