Common Name The Subequal Stelis [referring to the similarity to Stelis cubicularia]

Flower Size .08" [2 mm]

Found in La Paz department of Bolivia at elevations around 1550 meters as a mini-miniature to small sized, cool growing, caespitose epiphyte with erect, slender ramicauls enveloped by a tubular sheath near the middle and 1 to 2 others below and at the base and carrying a single, apical, erect, coriaceous, narrowly elliptical, acute apically, narrowly cuneate below into the petiolate base leaf that blooms in the early summer on an erect, arising through a spathe from a node below the apex of the ramicaul, peduncle .8" [2 cm] long, rachis 1.2 to 2" [3 to 5 cm] long, erect, strict, distichous, congested, simultaneously many, many flowered inflorescence with tubular, acute, a longer than to shorter than the the ovary floral bracts and carrying light yellow green flowers.

"This species is related to Stelis cubicularia, but differs by a smaller, loose habit with a single, shorter inflorescence. The synsepal is smaller with simply adherent lateral sepals. The petals are transverse, wider than long and three-veined with a transverse carina. The deeply concave lip is similar with an incurved apex, but the bar is lower than the rounded, basal angles. The rostellum is similar, but much larger with a thin, membranous center." Luer & Vasquez 2018
