Full shade Hotto Cool Winter Spring Summer Fall

Common Name The Silvery Stelis [refered to the color of the originally described flower]

Flower Size 1/4" [6 mm]

Found at elevations of 120 to 2200 meters as a miniature sized, hot to cool growing epiphyte in Mexico, Guatemala, Nicaragua, Costa Rica, Panama, Colombia, Ecuador, Peru, Venezuela, Guyana, Surinam and Brazil in tropical rainforests with clustered, lightly complanate ramicauls enveloped by a large, subinflated tubular, scarious sheath and a single, apical, oblong, tapered to the base into the cuneate petiole, slightly tridentate at the apex, coriaceous leaf that blooms at any time fo the yearon an erect, 4" [10 cm] long, racemose, several to many flowered inflorescence with minute floral bracts .

This is a color variable species and comes in many colors and sizes, but the labellum structure is definitive. I am positive of the photos veracity as S argentata.

Similar to S agatha but it is distinguished by a crowded, distichous raceme of large flowes with five-veined dorsal sepals, thick, fleshy petals and a rounded lip with a minute, marginal apiculum
