Stelis hammelii Luer 2001 TYPE Drawing by Carl Luer and The Epidendra Website

Common Name Hammel's Stelis [American Botanist and Collector of species current]

Flower Size .08" [2 mm]

Found in Costa Rica at elevations around 100 meters as a miniature sized, hot growing epiphyte with erect, slender ramciauls enveloped by a tubular sheath near the middle and 2 to 3 others at the base and carrying a single, apical, erect, coriaceous, narrowly elliptical, subacute, narrolwy cuneate below into the petiolate base leaf that blooms in the spring on an erect, slender, congested, disitchous, to 3.2 to 6" [8 to 15 cm] long including the .8" [2 cm] long peduncle, mostly simultaneously many flowered inflorescence arising through a slender spathe from an annulus at the apex of the ramicaul and has tubular floral bracts.

Similar to S cleistogama but S hammelii has a medium habit, with ramicauls shorter than the elliptical, petiolate based leaves and a shorter congested, distichous, inflorecence subtended by a much shorter spathe, with inconspicous floral bracts and ovate, obtuse sepals that are not widely spread.
