Common Name The Pyramidal Stelis [refers to the shape of the callus on the lip]
Flower Size .08" [2 mm]
Found in Antioquia department of Colombia in cloud forests at elevations around 2300 meters as a miniature sized, mat forming, cold growing, shortly ascending epiphyte with erect, slender, short ramicauls enveloped by 2 to 3, tubular, fibrous sheaths and carrying a single, apical, erect, coriaceous, narrowly linear-elliptic, subacute, tridenticulate, cuneate below into the petiolate base leaf that blooms in the spring on an erect, arising through a spathe, slender, distichous, 2.4 to 3.2" [6 to 8 cm] long including the .8 to 1.2" [ 2 to 3 cm] long peduncle, laxly many flowered inflorescence with infundibular, obtuse, slightly longer than the ovary floral bracts with a dorsal notch below the edge and carrying small yellowish flowers.
"The plant of S. pyramidalis resembles that of S. pusilla in that both form dumps of stem with narrow leaves and with long racemes with small yellowish flowers, but it may be distinguished from the last species by its labellar callus in the form of a truncated pyramid. Other species of Stelis, among them S. lanceolata and S. parvilabris, have raised prominent callus of the lip, but the habit of the plant and the structure of the flower is different. The prescence of a circular notch in the floral bract of S. pyramidalis is also distinctive. O Duque 2008
