Stenochlaenaceae Ching, Acta Phytotax. Sin. 16: 18 (1978).

Note:—The genus Doodia is embedded in Blechnum (Shepherd et al. 2007) . Combinations for these are presented below. Blechnum in its current circumscription, even including Doodia, is likely to be paraphyletic. The status of other genera such as Brainea, Pteridoblechnum, Sadleria, Salpichlaena and Stenochlaena is therefore not yet clear, but some of these should probably be included in Blechnum sensu lato (see Cranfill 2001). Further studies on the generic delimitation in this family are necessary.
