Oncidium callacallaense

A cool-growing Peruvian species formerly Odontoglossum callacallaense, named for the Calla Calla pass in Amazonas, Peru, a high wet Andean ridge above 3,000 m. The measured climate here comes from a lowland placeholder and should be ignored; grow it cool and constantly moist like other high-elevation odontoglossums.
