Lycopodiaceae is a large, cosmopolitan family that has its greatest diversity in humid montane forests and alpine areas of tropical regions, but also extends into the temperate zones. It is represented in New Zealand by five indigenous genera (Huperzia, Lycopodiella, Lycopodium, Phlegmariurus and Phylloglossum) and 12 species, of which only Phlegmariurus billardierei is endemic. Huperzia, characterised by its lack of strobili and the presence of bulbils, has a single terrestrial species in New Zealand that occurs in montane to alpine areas of both main islands. Lycopodiella includes four species: L. cernua, with looping stems, is a widespread tropical species common in the northern half of the North Island and extending to the West Coast of the South Island; L. diffusa and L. lateralis are found on pākihi and other poor soils in both islands and are characterised by strobili borne laterally on the aerial stems; and L. serpentina is a rare and threatened species found only on boggy soils around Kaitāia and between Thames and Hamilton. Lycopodium includes four mostly widespread species: L. scariosum and L. volubile are scrambling species with dimorphic sterile leaves flattened in one plane; L. fastigiatum is a montane to subalpine species with incurved leaves and stalked strobili; and L. deuterodensum is a lowland species of the northern North Island with dendroid aerial stems and sessile strobili. Two widespread species are now recognised in Phlegmariurus, both of them either epiphytic pendent plants of forest, or terrestrial plants of more open areas. Phylloglossum is a very distinctive monotypic genus of gumland and poorly drained soil in Northland and Auckland.
Members of Lycopodiaceae in New Zealand are representative of the range of variation in the family as whole, with terrestrial, epiphytic, scrambling and climbing species. They are characterised by monomorphic or dimorphic non-ligulate leaves with single, unbranched veins, and isotomous or anisotomous branching. Sporangia are homosporus, solitary on the adaxial surface of the sporophylls, and usually aggregated into strobili.
