Common Name or Meaning The Flexous Stelis

Flower Size 1/16" [3mm]

Found from Venezuela, Colombia, Ecuador, Peru and Bolivia at elevations of 1200 to 3950 meters as a miniature sized, cold to cool growing, caespitose terrestrial or lithophyte with a very slender stem enveloped basally by 2 to 3 tubular sheaths ans carrying a single, apical, oblanceolate to narrowly obovate, marginate leaf that gradually narrows into a short petiole that blooms in the summer 1 1/4 to 3 3/4" [3 to 9 cm] long, suberect to arcuate, filiform, fractiflex, racemose, several to many flowered inflorescence with minute, infundibuliform, shorter than the ovary floral bracts and carrying very small, membraneous, red flowers.

CAUTION!!!! This determination seems suspect to me. I await further information but does not jive with Foldats nor Dunsterville, but the photo provided in Duque's compendium is very similar but has a rounded lip apex and the photo it is very angular. Kew puts thisone as a synonym of S concinna but I have left them separate for now.

SEE ALSO Stelis cuencana and S concinna which are very similar. S concinna is said to be synomonous with this species and if so then S concinna takes precedence. Stelis flexuosissima is also very similar.

Synonyms Stelis tolimensis Schltr. 1924
