Oncidium praenitens

A Colombian endemic, described by Reichenbach in 1875 as Odontoglossum praenitens. Like the other former odontoglossums, it has since been moved into Oncidium. The Colombian plant catalogue records it in the Andes at 2000 to 2700 m and lists it as Vulnerable. Grow it as a cool cloud-forest epiphyte with cool nights, constant moisture and lots of moving air.

Where it grows wild

It is an epiphyte in Andean montane cloud forest, the typical habitat of Colombian odontoglossums. The air there is cool, misty and moving, and roots dry only briefly between rain and fog.

2000 to 2700 m in the Colombian Andes.
