Oncidium castaneum

Oncidium castaneum is an old Reichenbach name that GBIF treats as a synonym of Oncidium dichromaticum in two of its three entries, and it is absent from the list of accepted Oncidium species. As O. dichromaticum it is an epiphyte of Colombia, Costa Rica and Panama at low to middle elevations, so it wants warm-intermediate conditions.
