Common Name Delasota's Stelis [Named for Prof. Ramón Elías de la Sota of the Universidad Nacional de La Plata, Argentina, who collected this species 1932-2014]

Flower Size .2" [5 mm]

Found in La Paz department of Bolivia at elevations around 2200 meters as a miniature sized, cold growing, shortly repent epiphyte with erect, stout ramicauls enveloped by a tubular sheath near the middle and 1 to 2 tubular sheaths below and at the base and carrying a single, apical, erect, coriaceous, elliptical, acute, cuneate below into the petiolate base leaf that blooms in the summer on 1 to 2 , erect, arising through a slender spathe from a node below the apex of the ramicaul, peduncle stout, .8 to 1.2" [2 to 3 cm] long, rachis 1.2 to 3.2" [3 to 8 cm] long, erect, subflexuous, loose, simultaneously many, numerous flowered inflorescence with oblique, acute, shorter than the ovary floral bracts.

"This species is characterized by a stout, ascending rhizome that bears a petiolate leaf and one or two, subflexuous, loosely flowered racemes. The sepals are broadly ovate and densely short-pubescent; the petals are thickly margined and faintly three-veined; and the lip is shallow with the truncate apex minutely apiculate. Stelis delasotae Luer is similar to the variable S. argentata Lindl., but differs in the stout, ascending rhizome; the thick petals with a thick, rounded margin; and a flat, apiculate lip with a narrow, transverse cavity."
