Oncidium obryzatum

Oncidium obryzatum is an epiphytic orchid from Panama and the northern Andes (Colombia, Venezuela, Ecuador and Peru), described in 1854 and at times placed in Odontoglossum or Vitekorchis. It grows mainly in humid montane forest at about 1,000 to 2,100 m and is often seen on shade trees near villages and farms. Grow it intermediate and bright, with even moisture while growths develop and a slightly drier spell once they mature.

Where it grows wild

Records come from humid montane and cloud forest, forest edges, pastures with scattered trees and shade trees in villages around places such as Mindo, Nanegal, Boquete, El Valle de Antón and the Medellín area. It seems tolerant of disturbed, fairly open sites where it grows on branches in bright, broken light.

GBIF records with elevations cluster at about 1,000 to 2,100 m (median about 1,550 m). Outlying values (63 m, a 0 m entry for Medellín, and 2,600 m in the Bogotá botanic garden) are an error or cultivated plants.
