Common Name The Square-shaped Lip Stelis

Flower Size .08" [2 mm]

Found in La Paz and Cochabamba departments of Bolivia at elevations around 1820 meters as a mini-miniature sized, cool growing, caespitose epiphyte with erect, slender ramicauls enveloped by a loose, tubular sheath and 1 to 2 others at the base and carrying a single, apical, erect, coriaceous, elliptical, subacute, contracted below into the petiolate base leaf that blooms in the early summer on an erect, arising from a nodebelow apex of the ramicaul, peduncle 1.6 to 2" [4 to 5 cm] long, rachis .8 to 1.2" [2 to 3 cm] long, erect, strict, congested, simultaneously many flowered inflorescence with oblique, acute, as long as the ovary floral bracts and carrying light yellow flowers.

"This tiny, caespitose species is distinguished by minute flowers in a crowded, distichous raceme that far surpasses the leaves. The sepals are obtuse, convex and densely short-pubescent, and the petals are three-veined. The glenion of the subquadrate lip extends onto the dorsum where a second part completes the appearance of a dumbbell." Luer & Vasquez 2018
