Where it grows wild

Epiphyte high in the upper branches of rainforest trees, especially on ridge tops exposed to breezes and mist. It is a plant of the bright, airy upper canopy rather than the forest interior.

Eleven records with elevations span 700–1100 m (median 960 m). Floras say it grows mostly at higher altitudes.
