Common Name The Serrania de Paraguasa Stelis [Named for the Serrania de los Paraguas where the species was collected.]

Flower Size .12" [3 mm]

Found in Antioquia and Valle de Cauca departments of Colombia at elevations around 2000 to 2700 meters as a small sized, cold growing, caespitose epiphyte with erect slender ramicauls enveloped by a tubular sheath above the middle and another 2 to 3 near the base and carrying a single, apical, erect, coriaceous, ovate, acute, contracted below into the distinct petiolate base leaf that blooms in the late fall on 3 to 4, erect, arising through a spathe from an annulus below the apex of the ramicaul, peduncle .6 to .8" [1.5 to 2 cm] long, rachis 1.4 to 1.6" [3.5 to 4 cm] long, loosely, mostly simultaneously, many flowered inflorescence with acute, longer than the pedicel floral bracts and carrying yellow flowers.

"This species from the Western and Central Cordilleras of Colombia is distinguished by slender ramicauls that are distinctly longer than the leaves, and a few many-flowered racemes about as long as the leaves. The color of the floral parts varies from yellow to purple; the inner surface of the sepals varies from glabrous to pubescent. The sepals are either 3-veined or five-veined. All combinations of color, the integument and venation occur. The petals are thick and 3-veined below a transverse carina. The lip is rounded at the apex, and a cleft bar is continuous into a central, suborbicular callus on the dorsum. Although, as conceived, this species is frequent and exceedingly variable in a wide distribution, no other name can be applied. Most distinctive are the ramicauls longer than the leaf, and the central, solitary, round callus on the dorsum of a cleft bar of the lip." Luer 2018
