A rabbit's-foot fern from the rainforests of Samoa and the Santa Cruz Islands, creeping its furry rhizomes over tree trunks and branches. It wants warm, steady, humid conditions with bright shade and quick-draining footing.

Epiphytic on trunks and branches in lowland to montane rainforest, occasionally on mossy rocks. Habitat is inferred from the genus and the few Samoan records; species-specific notes are scarce.

The main record site on Upolu is at about 760 m.
