Icarus is a genus of ferns in the family Blechnaceae, subfamily Blechnoideae, with a single speciesIcarus 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]
Icarus filiformis, synonymBlechnum filiforme,[2] is known as thread fern or pānoko in Māori. It is endemic to New Zealand. It has a creeping and climbing habit. It has three different types of fronds: long climbing fronds with long pointed leaves, shorter creeping fronds with nearly round leaves, and fertile fronds with threadlike leaves that give the species its common name.[5]
