Doodia media, also known as rasp fern (or pukupuku in Māori), is a fern species in the Blechnaceae family. The species was formally described by botanist Robert Brown in 1810. Distribution of the species includes New Zealand's North Island and the upper part of the South Island (Nelson and Marlborough). It is also found in Australia and Lord Howe Island.
Young fronds contain flavonoids that protect them from ultraviolet radiation and give them a pink colour.
Phylogenic studies have shown that the Doodia genus is embedded within the paraphyletic genus Blechnum. Christenhusz et al., 2011, therefore reassigned all Doodia species to Blechnum. Doodia media R.Br. was transferred to Blechnum medium (R.Br.) Christenh. and Doodia media subsp. australis Parris (Doodia australis) was transferred to Blechnum parrisii Christenh..
