Found in southern Ecuador at elevations of 2100 to 3100 meters as a medium sized, cold growing, caespitose epiphyte with simple, cane-like, terete, erect, straight stems carrying 6, all along the apical half of the stem, alternate, articulate, narrowly elliptic, acuminate, margin entire leaves that blooms in the late winter through mid fall on a terminal, without a spathe, occuring only once, peduncle to 1.8" [4.5 cm] long, thin, laterally compressed, provided in the middle with a single, conduplicate, linear-lanceolate, acuminate bract that is similar to the bracts subtending the branches, paniculate, arching, lax, simultaneously 25 flowered inflorescence with much shorter than the ovary, linear-lanceolate, acuminate, amplexicaul floral bracts and carrying resupinate, green flowers with the lip and the apical half of the column white, and the lip with purple [maroon] dots near the base.

"Epidendrum vallisoletanum belongs to the GROUP Pseudepidendrum which is characterized by caespitose plants, cane-like stems, acute to acuminate leaves, usually apical inflorescence, the mostly filiform petals and the lip usually 3- lobed with 3 parallel fleshy keels, the apical lobe often bifurcate, the “bird-wing” type pollinia, at least the inner pair, and the SUBGROUP Paniculatum, which has filiform petals, all pollinia “bird-wing” type, green and white flowers, often marked with purple on the disc of the lip and apex of the column. The species is recognized by the short plants, about 14"[35 cm] tall, green and white flowers, with purple dots on the base of the lip, the sub-quadrate lateral lobes of the lip with the apical margin erose, the single callus apically bilobed and the papillose ovary. Epidendrum jasminosmum Hágsater & Dodson has taller plants 24 to 28" [60-70 cm] tall with pale green and white, immaculate flowers, the lateral lobes of the lip sub-rectangular, the posterior margin erose, and the lip bicallose, the calli narrow and prominent, the ovary is unornamented, the flowers are fragrance of Jasmine. Epidendrum paniculatum Ruiz & Pav. is endemic to Peru, also has green and white flowers, the lip marked with red-purple dots on the disc of the lip, but the lateral lobes of lip are sub-orbicular, and the mid-lobe forms two long, narrow lobes which are falcate and arch up, somewhat parallel to the margin of the lateral lobes, the lip is bicallose with two small, sub-globose calli. Epidendrum christensonii Hágsater & E.Santiago, which is also found near Valladolid and south into Peru has green flowers, with a white, immaculate, bicallose lip, the lateral lobes are obliquely elliptic and the mid-lobe is short, deeply bilobed, the lobes strongly divergent, forming a 180° angle."
