Where it grows wild

No species-specific habitat account was reachable, so this is built from the measured records and from what is typical for Adiantum from a seasonally dry region; it most likely survives in shaded, moister spots such as gallery forest, ravines and rocky banks.

Recorded at 150–750 m (median 320 m): lowland.
