Common Name Stefana's Bifrenaria [Stefana Solacolu - Brazilian Orchid Enthusiast 20th cen.]
Flower Size 3/4" [2 cm]
Found in the coastal Atlantic forest, in the southeast area of Brazil in montane rainforests at elevations of 500 to 1200 meters as a small to just medium sized, warm to cool growing epiphyte with conical, four sided, slightly compressed pseudobulbs carrying a single, apical, plicate, elliptic, acuminate leaf and blooms in the late summer and early fall in Brazil on a basal, racemose, erect, rigid, to 6" [to 15 cm] long inflorescence.
Similar to B vittelina, this species differs in having the sepals parallel to the column and lip, the wider than long midlobe of the lip and the callus that is close to the midlobe instead of close to the claw of the lip as in B vittelina.
