Phymatosorus diversifolius (syn. Microsorum)

From Australia and New Zealand this Polypodium relative is sometimes found as an epiphyte on imported tree fern trunks. Can form impressive colonies as a climbing plant on trees, banks or walls in mild areas, even up to 5m off the ground. Glossy evergreen fronds are either simple, as juveniles, or pinnatifid, as adult. Not tried outside here yet but excellent on the West coast.
