Ecology

Known from only 2 localities. At one locality it grows on twigs overhanging a stream, and the second locality is a sheltered ridge with the plants growing on small shrubs. Being small and easily overlooked explains why the species is rarely collected.

Highly localised.

Flowering period: August-September.
