Icarus filiformis, synonym Blechnum 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]
