Common Name The Clawed Sepal Stelis [referring to the tips of the sepals]

Flower Size .08" [2 mm]

Found in La Paz department of Bolivia at elevations around 1150 meters as a just mini-miniature to small sized, cool growing, caespitose epiphyte with erect, slender ramicauls with a tubular sheath from below the middle and 1 to 2 others below and at the base and carrying a single, apical, erect, coriaceous, elliptcal, acute, narrowing below into the petiolate base leaf that blooms in the early summer on 1 to 3, erect, arising through a spathe from a node below the apex of the ramicaul, peduncle stout, .4 to 1.2" [1 to 3 cm] long, rachis 1.6 to 3.2" [4 to 8 cm] long, erect, strict, sublax, mostly simultaneously, many flowered inflorescence with tubular, obtuse, as long as the the ovary floral bracts.

" This species, apparently endemic in an area of central Bolivia, is related to the familiar Stelis hylophila Rchb.f. that is found through the Andes from Colombia into Bolivia. Stelis onychosepala differs with racemes about as long as the leaf; densely short-pubescent sepals with recurved tips, that of the dorsal sepal with a small, uncinate process, those of the lateral sepals with a small, acute process; single-veined petals; and a minute, lip with a rounded apex.."
