The Lycopodiaceae (class Lycopodiopsida, order Lycopodiales) are a family of vascular plants, including all of the core clubmosses. These plants bear spores on specialized structures at the apex of a shoot; they resemble a tiny battle club, from which the common name derives. They are non-flowering and do not produce seeds.
The genera Huperzia, Phlegmariurus and Phylloglossum, the species of which were generally included in a more broadly defined Lycopodium in older classifications, are treated in the separate family Huperziaceae in some classifications, and are treated so here; they differ in producing spores in small lateral structures in the leaf axils. There is as yet no consensus on the recognition of Huperziaceae as a separate family; a more broadly defined Lycopodiaceae, including these genera, is still recognized in some classifications.
The species within this family generally have chromosome counts of n=34. A notable exception are the species in genus Diphasiastrum, which have counts of n=23.
Uses
- The running clubmosses (genus Diphasiastrum) have long been used as greenery for Christmas decoration.
- The spores have long been used as a flash powder. See Lycopodium powder.
- The spores have been used by violin makers for centuries as a pore filler.
- In Cornwall, club mosses gathered during certain lunar phases were historically used as a remedy for eye disease.
