Шаблон:Short description Шаблон:Speciesbox

Doodia media, also known as rasp fern (or pukupuku in Māori),[1] is a fern species in the family Blechnaceae. The species was formally described by botanist Robert Brown in 1810.[2][3] Distribution of the species includes New Zealand's North Island and the upper part of the South Island (Nelson and Marlborough).[1] It is also found in Australia and Lord Howe Island.[4]

Flavonoids colour the tips of young fronds pink.

Young fronds contain flavonoids that protect them from ultraviolet radiation and give them a pink colour.[1]

Phylogenic studies have shown that the genus Doodia is embedded within the paraphyletic genus Blechnum,[5] when that genus is broadly circumscribed. Christenhusz et al., 2011, therefore reassigned all Doodia species to Blechnum. Шаблон:Tx was transferred to Blechnum medium and Doodia media subsp. australis (Doodia australis) was transferred to Blechnum parrisii.[6] Other sources, such as World Ferns, based on the Pteridophyte Phylogeny Group classification, split Blechnum, accepting Doodia.[7]
