TaxonomyBlechnaceae was created by Newman in 1844 and has included a variable amount of genera. The Pteridophyte
Phylogeny Group classification of 2016 included 24 genera in
Blechnaceae. Some genera were placed in the separate family
Onocleaceae. The family is divided into three subfamilies. Alternatively,
Blechnaceae may be treated as the subfamily Blechnoideae of a very broadly defined family
Aspleniaceae, as Christenhusz and Chase propose.
Plant theoryBlechnaceae is treated as a family in the order
Aspleniales and Subclass
Aspleniidae. It is placed in subphase 1.
