Anemia (plant) explained

Anemia is a genus of ferns. It is the only genus in the family Anemiaceae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Alternatively, the genus may be placed as the only genus in the subfamily Anemioideae of a more broadly defined family Schizaeaceae, the family placement used in Plants of the World Online . Its species are sometimes called flowering ferns, but this term is more commonly applied to ferns of the genus Osmunda. Fronds are dimorphic; in fertile fronds, the two lowermost pinnae are highly modified to bear the sporangia.

Ferns in this genus have chromosome numbers based on x=38: n=38, 76, 114.

Taxonomy

The genus Anemia was first described by the Swedish botanist Olof Swartz in 1806. The family Anemiaceae was created by Johann Link in 1841. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), Anemia includes Mohria and Colina and is the only genus in the family. Some sources do not separate the family Anemiaceae from Schizaeaceae.[1]
