I. LYCOPODIACEAE View in CoL 1
Herbaceous or suffruticose, with more or less elongated branches bearing small leaves which are without veins or with a midrib only; ligule absent. Homosporous; sporangia in the axils of leaf-like sporophylls, frequently in spikes. Prothallus subterranean, mostly saprophytic and with mycorrhiza.
The family is sometimes divided into Urostachyaceae (Huperzia) and Lycopodiaceae (with the remaining genera); a more conservative treatment is adopted here.
