Common Name The Arrow Stelis [refers to the floral bracts]

Flower Size .24" [6 mm]

Found in La Paz department of Bolivia at elevations around 2630 meters as a mini-miniature sized, cold growing, caespitose epiphyte with erect, relatively stout ramicauls enveloped by a tubular sheath near the middle and another at the base and carrying a single, apical, erect, coriaceous, narrowly elliptical, subacute to obtuse, cuneate below into the petiolate base leaf that blooms in the later spring on an erect, arising through a sheath from a node below the apex of the ramicaul, peduncle .8 to 1.2" [2 to 3 cm] long, rachis 2.4 to 2.8" [6 to 7 cm] long, erect, strict, congested, mostly simultaneously many flowered inflorescence with dark purple, oblique, acute, with as longer than the ovary floral bracts and carrying dark purple flowers.

"This small, caespitose species is spectacular when in full flower, with most ramicauls producing a long raceme filled with purple or yellow flowers. The long, pointed floral bracts conceal both the pedicel and ovary of the flower. The petals are thickened and subacute at the tip. The lip is concave below a thin bar with a small glenion as a continuation of a low, broad, rounded callus on the dorsum." Luer & Vasquez 2018
