Doodia australis is a common hardy low growing fern that forms clumps (0.3m high and a spread of 0.5m) in coastal open sites or light scrub in sunny, dry conditions. It is found on the Kermadec Islands, the Three Kings islands and the North and South Islands from Te Paki south to Wellington, the Marlborough Sounds, north-west Nelson and the Banks Peninsula. It is also found in Australia and Lord Howe Island.
It is called the rasp fern because its fronds are somewhat harsh to touch.
Doodia australis is distinguished from the other New Zealand Doodia species by the pink to red colour of the young emergent fronds. Flavonoids colour the tips of young fronds pink. Young fronds contain flavonoids that protect them from ultraviolet radiation and give them a pink colour.
