Oncidium bohnkianum V.P.Castro & G.F.Carr 2006 SECTION Barbata Photo by Orchidario Imirim

Fragrance Part shade Warm Summer

Common Name Bohnk's Oncidium [Brazilian Nurseryman and Orchid Enthusiast current]

Flower Size 2" [5 cm]

Found in southeastern Bahia as a small sized, warm growing epiphyte that blooms in the summer on a pendent, many flowered inflorescence and carrying slightly fragrant flowers

This species is related closely to O uniflorum and O longipes but differs in the plant much larger than 20 cm tall, the lack of a triangular callus disc with the fimbriate or ciliate margins, and instead an acute narrowing between the midlobes and the lateral lobes and has a shorter column with fimbriate wings.

Newer references put this species as a synonym of O uniflorum but I have left them separate for now.
