Oncidium cariniferum
A cool-growing epiphytic Oncidium from the lower montane forests of Costa Rica and western Panama, usually at about 1,000–2,400 m. It carries compressed, grooved pseudobulbs with two leaves and branched sprays of greenish-brown flowers with a whitish lip. It wants steady mild days, cool nights and wet, cloudy air all year, not the warm windowsill conditions of hybrid Oncidiums.
Where it grows wild
Epiphytic on the larger branches of trees in lower montane and cloud forest, where rain and cloud keep the air humid for most of the year. Plants sit in the brighter mid and upper parts of the trees rather than on shaded lower trunks.
Recorded elevations run from 100 to 2,050 m, but the median is 1,900 m and the literature gives about 1,000–2,400 m. Treat it as a cool montane plant; the lowest records are likely georeferencing errors or stray lowland collections.
