Oaxaca Mx., 2377m elev., along road to Putla, epiphytic on oaks.

Found in Mexico, Guatemala, and El Salvador occuring in the evergreen cloud forests and damp pine/oak forests at altitudes of 2300 to 2800 meters as a small to medium sized, cold growing, reedstem epiphyte with leaves clustered towards the apex with erect stems enveloped by tubular, scarious sheaths and carrying elliptic, subcoriaceous, acute, basally clasping leaves clustered towards the apex that flowers on a terminal, racemose, 3/8" long, arcuate, few to several flowered inflorescence arising on a newly maturing cane with successive opening, nocturnally, foul-smelling flowers that appear from winter through spring.

"Epidendrum eximium is the typ of GROUP Eximium characterized by the relatively short plants to 16" [40 cm] tall, the sympodial, non-branching, few leafed stems that blooms on an apical, generally racemose inflorescence that is short, shorter than the apical leaf and carrying bell shaped, showy, greenish yellow to green with brown or purple tinted flowers with an entire lip, and very small calli. The species has caespitose plants 8 to 20" [20 to 50 cm] high, with 3 to 5 elliptic leaves which generally are .8 to 1.2" [2 to 3 cm] wide, the short, arcuate raceme with large yellow to greenish flowers, usually with the basal half of the segments and the column flushed with burgundy red, the segments .6 to 1.04" [15 to 26 mm] long and the lip cordiform to suborbicular, permit a rapid identification. Its closest relative seems to be E. sobraloides from Guatemala, and recently discovered also in Chiapas, but the obovate lip and the narrow leaves of the latter are very distinctive."
