Found in Brazil, Santa Cruz department of Bolivia and Missiones state of Argentina at elevations around 1350 to 1500 meters as a miniature sized, cool growing, shortly repent to caespitose epiphyte with an erect, stout ramicaul enveloped basally by 2 to 3, tubular sheaths and caryring a single, apical, erect, coriaceous, elliptical, gray-green, tridenticulate apically leaf that blooms in the summer on an erect to arching, 2" [5 cm] long, few to several [to 8] flowered inflorescence with close, tubular, longer than the ovary flora lbracts, and carrying fleshy, pubescent flowers.

"The stout ramicauls, slightly shorter than the thickly coriaceous, sessile leaves are clad in hispidulous sheaths. The several flowered raceme equals or surpasss the leaf. With the dorsal sepal deeply connate to the synsepal, the thick, fleshy sepals form a more or less erect, tubular flower. The petals are denticulate and apiculate and with the central calli and biauriculate base the lip is also similar to other members of the subgenus." Luer 2004
