Common Name The White Purple Stelis

Flower Size .2" [5 mm]

Found in Choco department of Colombia at elevations around 2500 meters as a mini-miniature to miniature sized, cold growing, long repent epiphyte with stout, erect ramicauls enveloped by tubular, evanescent sheaths and carrying a single, apical, erect, coriaceous, elliptical, acute, contracted below into the slender, petiolate base leaf that blooms in the later summer on a single, arising through a spathe within a sheath from a node below the apex of the ramicaul, peduncle .6 to .8" [1.5 to 2 cm] long, erect, congested, strict, rachis 6.8" [17 cm] long, secund, mostly simultaneously many flowered inflorescence with purple, obique, acute, as long as the ovary floral bracts.

"This long-repent, distinct species of section Humboldtia is characterized by a red-purple dorsal sepal that is longer than a white, ovoid synsepal over which it hovers. Unfortunately the flowers do not rehydrate well, leaving details of the minute central apparatus poorly visualized. The petals are concave and three-veined with the thickened, rounded margin. The minute lip is apparently transversely bilobed with the lateral lobes rounded and larger than the middle lobe." Luer 2017
