Found in Ecuador on roadside banks and in humid montane forests at elevations around 2450 to 3100 meters as a medium sized, cold growing epiphyte or terrestrial with cane-like, branching, terete stems carrying numerous, all along the stem, alternate, narrowly lanceolate, unequally bilobed, margin entire, thin leaves that blooms in the fall on a terminal, racemose, arching, 2" [5 cm] long, several flowered inflorescence with much shorter than the ovary, triangular, acuminate floral bracts and carrying 10 simultaneously opening flowers.

"Epidendrum allisonii belongs to the GROUP Diothonea SUBGROUP Diothonea, recognized by its branching habit, apically bilobed leaves, and short nutant inflorescence, the lip obliquely jointed to the column; the species has a bilobed lip, truncate at the base and ovate, obtuse petals, and column somewhat arched with its apex arched upwards. It is similar to E. suavis (Rchb.f. & Warsc.) Lojtnant which has an entire, cuneate lip, and narrower, acute petals. Epidendrum diothonaeoides Schltr. has narrower, acute sepals and petals, and the column is united to the column throughout and blunt, .48" [1.2 mm] long." Hagsater etal 2001
