The family Polypodiaceae (excluding the grammitid ferns) is represented in New Zealand by three indigenous genera (Loxogramme, Microsorum and Pyrrosia) and five species, one naturalised genus (Polypodium) with a single species, and two casual genera (Niphidium and Platycerium) with one species each. Pyrrosia eleagnifolia and two species of Microsorum are widespread, but M. novae-zealandiae is confined to the North Island. Loxogramme dictyopteris occurs throughout the North Island and northern half of the South Island. Polypodium vulgare was first observed on the Port Hills, Christchurch, but has now spread aggressively north to Wellington. Platycerium bifurcatum and Niphidium crassifolium are known only from a few localities in northern New Zealand. Species of Polypodiaceae in New Zealand usually have long-creeping rhizomes, undivided to once-divided fronds, reticulate venation, and sporangia that are either arranged in round to ovate, bulging sori, or scattered over much of the lamina surface.
