Common Name The Very Small Stelis [referring to the central apparatus]

Flower Size

Found in La Paz department of Bolivia at elevations around 1850 meters as a miniature to small sized, cool growing, caespitose epiphyte with erect, slender ramicauls with a tubular sheath below the middle and 2 others at the base and carrying a single, apical, erect, coriaceous, elliptical, narrowly rounded, cuneate below into the petiolate base leaf that blooms in the early summer on 3, erect, arising through a spathe from a node below the apex of the ramicaul, peduncle .2" [5 mm] long, rachis .6 to 1" [1.5 to 2.5 cm] long, erect, secund, congested, mostly simultaneously many flowered inflorescence with oblique, acute as long as the pedicel floral bracts and carrying yellow flowers.

"This species is related to the frequent and variable Stelis euspatha Rchb.f., but is remarkable for the minute size of the central apparatus. The inflorescence consists of a few (three in the present specimens) racemes less than half the length of the leaf. The lateral sepals are single-veined and oblique with the lower margin longer and more or less dilated. The dimensions of the petals and lip are less than half a millimeter long."
