Oncidium blandum

A small, fragrant cloud-forest Oncidium, formerly Odontoglossum blandum, with cream flowers spotted brown and a lip that is yellow at the base. It is recorded from the Andes of Colombia (Ocaña, Santander) and south to Ecuador and Peru, at about 1000–2900 m. It is a cool-intermediate epiphyte that needs even moisture and moving air.
