Flower Size

Found in the Bismark Archipelago and the Solomon Islandson trees in forests at elevations around 600 meters as a miniature sized, warm growing epiphyte with a creeping rhizome giving rise to .4 to 1.2" [1 to 3 cm] between each ovoid, green pseudobulb carrying a single, apical, oblong-lanceolate, mid green, petiolate base leaf that blooms in the summer on a basal, 2 to 4.8" [5 to 12 cm] long, single flowered inflorescence carrying a purple flower edged with white and a bright orange to purple lip.

Schlechter states that this species is similar to B chrysoglossum but differs in the flower color which is dark purple, the more pointed leaves, the thickly covered papillae of the lip which is narrower and distinctly contracted from the middle and the column arms which are not 2 toothed but serrate in front.
