Found in Guerrero and Oaxaca states of Mexico at elevations around 1900 to 2550 meters as a small sized, cool to cold, pendant to hanging epiphyte with simple, thickened, fusiform pseudobulbs enveloped in youth by 3 to 6, papiraceous sheaths and carrying 3 to 5, aggregate towards the apex, subcoriaceous, elliptic to oblanceolate, acute, articulate below into the base leaves that blooms in the spring and summer on an apical, erect, racemose, cylindrical, terete, short, 3 to 8 flowered inflorescence with 1 to 2, conduplicate, oblong-triangular, acuminate to acute bracts and much shorter than the ovary, triangular, acuminate floral bracts and carrying simultaneous, nocturnally [soap] fragrant flowers arising on a newly developing to mature stem.

"Epidendrum hagsateri belongs to the GROUP Coilostylis which is characterized by the sympodial, caespitose, pendent plants, coriaceous to succulent leaves, apical, racemose inflorescence with a short peduncle, covered by 1 to 2, non spathaceous bracts, and the large, star-shaped flowers. The species is recognized by the inflorescence produced from the nearly mature pseudobulb, with 3 to 8 flowers, sepals and petals green to copper-brown, lip green to yellowish green, the disc occasionally tinged with red, callus red, column green, turning creamcolored towards the apex; lateral lobes of the lip sub-orbicular to sub-rectangular, mid-lobe triangular. It is similar to Epidendrum lacertinum Lindl. which also has green flowers and the lip occasionally red at the base, the mid-lobe purple, calli white, lateral lobes triangular, and the mid-lobe linear. Epidendrum falcatum Lindl. is lithophytic, with brittle plants, the stems forming fusiform, uni-foliate, pseudobulbs, the leaf coriaceous-succulent, flowers white, sepals pink without, calli yellow, mid-lobe of the lip clearly separated from the lateral lobes by deep sinuses Epidendrum parkinsonianum Hooker 1840 has long, pendent plants, to 80" [2 meters] tall, epiphytic, the stems terete, without forming pseudobulbs, flowers larger, sepals and petals generally 1.6 to 3.4" [40 to 85 mm] long, green to yellowish green, column and lip white, calli yellow, mid-lobe of the lip separated from the lateral lobes by deep sinuses, and generally much longer than the former, by .8 to 1.2" [2 to 3 cm] in length, nectary pilose."
