Oncidium mathieuanum

Oncidium mathieuanum was described by Reichenbach and Warszewicz in 1856 from Andean material, and is accepted as native to Ecuador and Peru. GBIF holds no wild records, so its exact habitat is unknown. This profile gives intermediate Andean Oncidium care built from two regional climate sites.

Where it grows wild

Not documented; assumed to be an epiphyte of humid montane forest on the eastern Andean slopes, as most Andean Oncidium are.

Unknown; the climate sites sit at 273 m and 1215 m, but Warszewicz-era Andean Oncidium are often from higher, cooler forest.
