Additional notes:     

• Taxonomy

  • The species was formally described by botanist Robert Brown in 1810

  • Phylogenic studies have shown that the genus Doodia is embedded within the paraphyletic genus Blechnum, when that genus is broadly circumscribed. Christenhusz et al., 2011, therefore reassigned all Doodia species to Blechnum

  • Doodia media R.Br. was transferred to Blechnum medium and Doodia media subsp. australis (Doodia australis) was transferred to Blechnum parrisii

  • Other sources, such as World Ferns, based on the Pteridophyte Phylogeny Group classification, split Blechnum, accepting Doodia
