Common Name The Mealy Stelis [referring to the callus on the lip]

Flower Size .24" [6 mm]

Found in La Paz department of Bolivia at elevations around 1800 meters as a mini-miniature to just miniature sized, cool growing, caespitose epiphyte with erect, slender ramicauls enveloped by 2 to 3 ribbed, tubular sheaths and carrying a single, apical, erect, coriaceous, elliptical, acute, cuneate below into the petiolate base leaf that blooms in the early summer on 2 to 3, erect, through a spathe from a node below the apex of the ramicaul, peduncle .4" [1 cm] long, rachis 1.6 to 2" [4 to 5 cm] long, erect, strict, congested, mostly simultaneously, many flowered inflorescence with oblique, acute, as long as the pedicel floral bracts and carryng light yellow flowers.

"Among the species with single-veined sepals, this species is distinguished by glabrous, elliptical-ovate sepals; ovate-triangular, membranous petals also with a single vein; and a thin, broadly ovate lip with an acuminate apex, and a thick, basal callus that is coarsely farinose. Stelis enervis Luer & R.Vásquez is similar, but differs withsepals that are long-pubescent near the margins, petals without a visible vein, and a non-farinose callus at the base of the lip."
