Common Name or Meaning The 2 Horned Stelis [refers to the acuminate points on the petals]

Flower Size .15" [4mm]

Found in Colombia, Ecuador, Peru and Bolivia at elevations around 1500 to 3500 meters as a medium sized, warm to cold growing epiphyte with erect, elongate ramicauls enveloped basally by 2 basal sheaths and another longer on on the upper half and carrying a single, apical, erect, coriaceous, oblong, obtuse, tridenticulate, gradually narrowing below into the petiolate base leaf that blooms in the winter on 1 to 2, erect to arching, distichous, slightly flexuos, 8" [20 cm] long, laxly to densely many flowered, racemose inflorescence arising through a spathe.

CAUTION This species and S langlassei have been considered to be conspecific by many with S bicornis taking precendence but I follow Luer in separating them. Please see S bisserula as it as well has been considered conspecific.

CAUTION I cannot be sure of the photos above so please use with caution!
