The family Psilotaceae is represented in New Zealand by two non-endemic genera (Psilotum and Tmesipteris) and six species, two of which are endemic. Psilotum nudum is confined to Northland, Auckland and the thermal regions. Two species of Tmesipteris are widespread in the North Island and western half of the South Island; two are largely confined to the northern half of the North Island with outlying populations in northern South Island, and one is endemic to Banks Peninsula. Psilotum nudum has branching, upright, angular stems with highly reduced, scale-like leaves, and trilobed synangia borne on the upper surface of bifid, scale-like sporophylls. Species of Tmesipteris are usually epiphytic, often on tree fern trunks, and have pendulous aerial stems bearing flattened leaves, and bilocular synangia on the upper surface of forked sporophylls. Neither genus appears typically fern-like in its morphology.
