Davallia formosana

A creeping rhizomatous fern of seasonally wet tropical and subtropical Asia, from southern China and Taiwan through Indochina to Malesia and New Guinea. Like other Davallia it runs its furry rhizomes over bark and rock, so it wants warmth, humid but moving air and a medium that never stays soggy.
