There are two major groups of large clubmosses: the Lycopodiaceae and the Huperziaceae.
The other major group, the Family Huperziaceae, are known as the firmosses.
This group includes the genusHuperzia, such as the Shining firmoss, Huperzia lucidula, the Rock firmoss, Huperzia porophila, and the Northern firmoss, Huperzia selago.
The family Huperziaceae is one of two families in the order Lycopodiales, and contains two or three extant genera:
The Huperziaceae was formerly included in the family Lycopodiaceae, but is distinct in having erect (not creeping) growth; and in its spore-bearing structures being produced in the axils of unmodified leaves, unlike the terminal club-like structure produced by species in the Lycopodiaceae.
