Common Name The Boat Bearing Stelis [referring to the concave synsepal]

Flower Size .04" [1 mm]

Found in La Paz department of Bolivia at elevations around 1400 meters as a miniature sized, cool growing, shortly repent epiphyte with erect, slender ramicauls with a tubular sheath near the base and another at the base and carrying a single, apical, erect, coriaceous, narrowly elliptical, subacute to narrowly obtuse, gradually narrowing below into the petiolate base leaf that blooms in the summer on an erect, peduncle [.8 to 1.8 cm] long, rachis .88" [2.2 cm] long, loose, simultaneously 5 to 9 flowered inflorescence with about as long as the ovary floral bracts and carrying glabrous, yellow-green flowers.

"The plants are very small and shortly repent with narrow leaves less than three centimeters long. The loosely flowered inflorescences exceed the leaves about twice their length. In the published description, the sepals are three-veined without dimensions; the lateral sepals are connate into a concave synsepal; the petals are single-veined; fide Schlechter, the lip is suborbicular, obtuse, with the apex slightly incurved, and about as long as the petals, nothing more (the lip from a rehydrated bud is oblong, obtuse, and concave between the halves of a cleft bar); fide Schlechter, the column is dilated and three-lobed. The "lateral lobes" are probably the stigmatic lobes." Luer & Vasquez 2018
