Found in Cusco department of southern Peru on the upper Amazon slope of the Andes at elevations of 2900 to 4137 meters as a small sized, cold growing epiphyte with a stem thickened into forming fusiform pseudobulbs, furrowed and rugose, covered by 3 progressively larger, membranaceous, scarious and becoming fibrous with age sheaths and carrying a single, apical, articulate, coriaceous, green-brown, narrowly elliptic, obtuse, margin entire, slightly revolute leaves that blooms in the winter on a terminal, erect, arising through a single, at the apex of the pseudobulb, tubular, oblong, conduplicate, apex rounded, brown spathe, peduncle 3.2" [8 cm] long, terete, thin, erect, straight, brown, 4.72" [11.8 cm] long including the flowers, apical, erect, racemose, simultaneously 5 flowered inflorescence 1.3-1.8 mm long, much shorter than the ovary, triangular-ovate, acute, embracing floral bracts and carrying non-resupinate, yellow flowers with the fragrance not registered.

"Epidendrum galianoi belongs to the GROUP Saxicola characterized by the pseudobulbous stems, caespitose or scandent habit, the prominent spathaceous bract apically rounded, few-flowered, erect inflorescence, the flowers purple or yellow, surface of the vegetative structures often rugose. The new species is recognized by de 5 flowered inflorescence, flowers yellow, sepals .84 to .88" [21 to 22 mm] long, elliptic, petals .76 to .88" x .2 to .24" [19 to 22 x 5 to 6 mm], narrowly elliptic, and the lip .54 x .64" [13.5 x 16 mm], widely cordiform when spread, calli globose, small, disc slightly fleshy between the calli, and a fleshy mid-rib reaching the apex of the lip. It is similar to Epidendrum milpoënse Hágsater & E.Santiago which has 2 to 3 green flowers per inflorescence, sepals .72 to .76" [18 to 19 mm] long, petals .64 to .7" [16 to 17.5 mm] long, rhombic-spatulate, and the disc of the lip with 3 parallel ribs that reach the apex of the lip. Epidendrum microcattleyioides D.E.Benn. & Christenson has 4 yellow flowers, sepals .48 to .52" [12 to 13 mm] long, petals .44 x .3" [11 x 7.0 mm], obovate, and a reniform lip, widely emarginate. Epidendrum saxicola Kraenzl. has two purple flowers, the lip white, sepals .68 to .72" [17 to 18 mm] long, petals .6 to .72" x .1 to .12" [15 to 18 x 2.5 to 3.0 mm], linear-oblanceolate, and the lip suborbicular to obscurely pentagonal. Epidendrum harmsianum Kraenzl. has 1 to 2 yellow flowers, sepals .64" [16 mm] long, petals .56" x .12" [14 x 4 mm], oblanceolate, and the lip transversely ovate-oblong." Hagsater etal 2020
