LATE

Common Name The Southern Barbosella

Flower Size 2" [5 cm]

Found in Rio de Janiero, Sao Paulo, Parana and Rio Grande do Sul states of southern Brazil at elevations around 1500 meters as a mini-miniature sized, cool growing, long-repent epiphyte with a creeping, branching rhizome giving rise to ascending, cylindrical ramicauls enveloped by sheaths and carrying a single, apical, suberect, elliptic-oblong, often suffused with purple, acute, conduplicate below into the sessile base leaf blooms in the summer on an erect, .6 to 1.4" [1.5 to 3.5 cm] long, terete, slender, single flowered inflorescence with a thin, oblique floral bract enveloping the pedicel and part of the ovary. It holds the single flower well above the leaves.

"Recognized by the creeping habit and conspicuous, membraneous flowers larger than most of the suberect, elliptical leaves. The flowers are characterized by the oblong lip, broadly forked at the apex and a pair of pyramidial calli on the disc in front of the basal cavity." Luer 2000
