Oncidium praestanoides

An Andean cloud-forest orchid long grown as Odontoglossum praestans. When Odontoglossum was merged into Oncidium in 2008 it needed a new name, because the epithet praestans was already taken in Oncidium. It grows in the eastern Andes from Colombia to Bolivia, with collections around 1,900–1,950 m in Peru and Bolivia, so it wants the cool to intermediate, misty, bright-shade conditions of classic odontoglossums.

Where it grows wild

Epiphyte in montane cloud forest ('Selva Andina' on one specimen label), where the forest is often in cloud, trees carry heavy moss and there is frequent drizzle.

Labelled specimens are from about 1,900 m in La Paz, Bolivia and 1,950 m in Cajamarca, Peru; the recent observations from Cusco and Cochabamba are in cloud forest at similar heights.
