Summary: Doodia scaberula Parris was Chase (2014) and Christenhusz et al. (2015) transferred to Blechnum as B. papuanum by for our systematic treatment. The present work Christenhusz in 2011, due the pre-existence is framed within the pteridology postgraduate of B. scaberulum Sodiro, a South American course of the San Marcos National University, at species. However, this is a later homonym of B. Lima, Peru (León 2015). papuanum Brause and thus, is here replaced by B. polinesicum. A brief description of this species is Systematics provided. Family Aspleniaceae Newman The genus Doodia R. Br. was erected by Subfamily Blechnoideae Hook. Robert Brown (1810) for New Zealand ferns. Genus Blechnum R. Br. It was differentiated from the closely related Blechnum polinesicum Molinari, nom. nov. Blechnum L. by the venation of the leaves ≡ Doodia scaberula Parris in Blumea 24(2): (Kramer et al. 1990) and the reniform, smaller 505 (1978), non Blechnum scaberulum Sodiro in spores of Doodia (Harris 1955, Tryon and Anales Univ. Centr. Ecuador 8(57): 211 (1893). Lugardon 1991). However, molecular studies ≡ Blechnum papuanum Christenhusz in discovered it was embedded in Blechnum, a Phytotaxa 19: 20 (2011), nom. illeg., non highly paraphyletic genus then (Cranfill and Blechnum papuanum Brause in Bot. Jahrb. Syst. Kato 2003, Smith et al. 2006, Lehtonen 2011, 56(1): 158 (1921). Rothfels et al. 2012). Therefore, Christenhusz Holotype: NEW GUINEA. Papua, Milne et al.
