Where it grows wild

The records come from the Valdivian temperate rainforest zone, where Blechnaceae grow on the shaded forest floor, banks and logs. Habitat detail for this species is inferred from that zone and the genus.

Recorded from sea level to about 520 m in the coastal ranges and lowlands of Los Ríos, Araucanía and Chiloé.
