Family Hymenophyllaceae Crepidomanes intricatum.JPG Crepidomanes intricatum In New York, only one species of this family has been verified as living outside of cultivation, and that species is considered to be endangered in the state. Crepidomanes Trichomanes intricatum1-BobKlips.jpg Crepidomanes intricatum The only member of the Hymenophyllaceae found in New York is a gametophitic weft fern Crepidomanes intricatum, which was transferred from Trichomanes to the mostly Asian Crepidomanes genus by Ebihara & Weakley (2011) based on molecular sequence. Crepidomanes intricatum is assumed to be gametophitic only. Sporophitic generations of this plant have not been observed.Weakley et al. (2011).

A single endangered species in each of the latter two families are present in New York. Family Lygodiaceae Lygodium palmatum NRCS-007.jpg Lygodium palmatum The Lygodiaceae (climbing-fern family) consists of the single genus Lygodium, which in New York, is represented by the endangered American climbing fern. No other Lygodium species are native to North America, and some have been found to be invasive in the southern U.S.Kenneth A. Langeland, Stephen F. Enloe, and Jeffery Hutchinson "Natural Area Weeds: Old World Climbing Fern (Lygodium microphyllum)" Lygodium Lygodium palmatum NRCS-005.jpg Lygodium palmatum The genus Lygodium contains about 40 species of climbing ferns, the only one of which is found in New York (and the only North American native) is the endangered American climbing fern or Hartford fern (Lygodium palmatum).

Azolla Azolla caroliniana 15-09-2012.JPG Azolla cristata, mosquito fern Azolla (mosquito ferns) have previously been placed in their own family, the Azollaceae. The taxonomy of the New World Azolla species has been in dispute - four species have been reported in the literature: A. caroliniana, A. filiculoides, A. mexicana and A. microphylla, but Evrard and Van Hove (2004) concluded that only two species exist in America and, according to the priority rule for nomenclature, they should be named A. cristata and A. filiculoides.The New York Flora Atlas states: "Evrard and Hove (2004) provide evidence that the correct name for this taxon is A. cristata and that A. caroliniana, which has been misapplied to A. cristata, is a true synonym of A. filiculoides."C.
