Species of fern From Wikipedia, the free encyclopedia
Icarus is a genus of ferns in the family Blechnaceae, subfamily Blechnoideae, with a single species Icarus filiformis, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).[1] The genus is accepted in a 2016 classification of the family Blechnaceae,[3] but other sources sink it into a very broadly defined Blechnum, equivalent to the whole of the PPG I subfamily.[4]
