Common Name The Putumayo Stelis [A Department of southern Colombia

Flower Size .2" [5 mm]

Found in Putumayo department of Colombia at elevations around 2700 meters as a small to medium sized, cold growing, densely caespitose epiphyte with erect ramicauls enveloped by a tubular sheath below the middle and 1 to 2 others below and at the base and carrying a single, apical, erect, coriaceous, elliptical-ovate, acute, gradually narrowing below into the base leaf that blooms in the summer on 2 to 4, simultaneous, erect, arising from a node below the apex of the ramicaul, peduncle .8 to 1.2" [2 to 3 cm] long, rachis 6 to 8" [15 to 20 cm] long, congested, strict, distichous, mostly simutaneously many flowered inflorescence with oblique, slender, acute, much longer than the ovary floral bracts and carrying glabrous flowers with red brown sepals and a yellow central apparatus. .

"With long, many-flowered racemes with long, acute floral bracts, and a concave synsepal, this large species is superficially similar to Stelis purpurea (Ruiz & Pav.) Willd. . However, the sepals are a little smaller and only 3-veined, with an obtuse, instead of acute, dorsal sepal, and the bar of the lip differs with a short cleft and a smooth dorsum." Luer 2016
