Common Name The Unduavi Stelis [Named for Villa Tunari, the community near the area where the species was collected]

Flower Size .24" [6 mm]

Found in Cochabamba department of Bolivia at elevations around 2800 meters as a mini-miniature sized, cold growing, caespitose ascending epiphyte with erect slender, ramicauls enveloped by a tubular sheath from below the middle and another at the base and carrying a single, apical, erect, coriaceous, elliptical, subacute, cuneate below into the petiolate base leaf that blooms in the early summer on an erect to arching, arising through a slender spathe from a node at the apex of the ramicaul, peduncle 2" [5 cm] long, rachis .4 to 3.2" [1 to 8 cm] long, erect, sublax, secund, long-pedicellate, about 10 to 12 flowered inflorescence with oblique, acute, much shorter than the pedicel floral bracts and carrying flowers with rose mottled, glasbrous sepals, green petals and a green below rose lip.

"This small species is similar to Stelis antennata Garay, but differs by a truncate apex of the petals with a setiform process produced by thickened veins, and a subquadrate lip that is shortly concave at the apex, a smooth, thick callus that extends from the truncate base to within the apical cavity. This little species is the fourth of a group that bears long-pedicellate flowers. It differs from all of them by a setiform tail emerging from a broadly truncate blade of the petals, and a thick, smooth, quadrate lip with a truncate, narrowly concave apex." Luer & Vasquez 2018

Similar to both S. ballatrix Luer & R.Vásquez and Stelis saltatrix Luer & R.Vásquez 2018
