Blechnum filiforme or thread fern (pānoko in Māori) is an endemic New Zealand fern species in the hard fern family, Blechnaceae.[1] The species authority is (A. Cunn.) Ettingsh.
Thread fern 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.[1]
