Oncidium millianum

Oncidium millianum was described by Reichenbach in 1878 and is accepted as native to Colombia. Nothing about its habitat was found and GBIF holds no wild records, so this profile gives generic intermediate Andean Oncidium care. The lowland climate site used is a placeholder and probably too hot.
