Common Name The Flat-Lip Oncidium

Flower Size about 1" [to 2.5 cm]

Found in Nicaragua, Panama and western Ecuador in tropical dry and moist forests as a small to medium sized, hot to cool growing epiphyte that is found at elevations of sealevel to 2500 meters with elliptical, ribbed pseudobulbs enveloped basally by several leaf bearing sheaths and carrying 2, apical, oblong-lanceolate leaves that blooms in the summeron an erect then arching, to 6' [to 180 cm] long, few branched inflorescence arising on a mature pseudobulb.

Similar to Onc panamense Schlechter but O planilabre differs in being a smaller plant, and the column is wingless, instead there are 3 downward projecting teeth over the stigma and a .08" [2 mm] long tubercle at the base of the crest. The arrows in the photo point to these teeth and tubercle.
