Oncidium bracteatum

A sizeable epiphytic Oncidium of wet montane forest in Costa Rica and western Panama, with long branched sprays of yellow-green, brown-barred flowers set off by conspicuous bracts. Over a hundred wild records place it at 1000–2400 m, so it is an intermediate-to-cool grower that wants mild days, cool nights and a short, gently drier winter.
