Common Name Lankester's Oncidium [American Botanist in Costa Rica Early 20th cen]

Flower Size 1" [2.5 cm]

Found in Costa Rica at elevations around 1800 to 2000 meters as a cool to cold growing epiphyte that blooms in the winter

Often Cited as a synonym of O lankesteri but if the photos are correctly identified then they appear different, I have left it separate until I have more inflromation.
