Found in Zamora-Chinchipe province of Ecuador at elevations around 3050 meters as a miniature to small sized, cold growing ascending, caespitose epiphyte with erect, slender, prolific ramicauls enveloped by a long tubular sheath above the middle and another at the base and carrying a single, apical, erect, coriaceous, elliptical, subacute to obtuse, cuneate below into the petioalte base leaf that blooms in the summer on an erect, peduncle 1.2 to 2.8" [3 to 7 cm] long, arising through a spathe [1 to 1.5 mm] long, with an annulus below the apex of the ramicaul, rachis 3.6 to 5.2" [9 to 13 cm] long, subdense, distichous to secund, simultaneously several, many flowered inflorescence with tubular, oblique, acute, shorter than the ovary floral bracts and carrying either yellow or purple flowers.

"Similar to S antennata in the petals and lip but the habit differs dramatically. S barbellata is a larger species with ramicauls bot caespitose and prolific, and has elliptical, petiolate base leaves surpassed by a subdense raceme of either yellow or purple flowers. From the center of the flowers protrudes a pair of barbel-like processes from the acuminate tips of the petals, the lip is oblong, concave and acute. The basal third is filled witha transverse, densely pubescent callus." Luer 2002
