club mossAny of a group of mosslike plants that do not produce seeds but reproduce by spores. They are related to the ferns and horsetails. (Order Lycopodiales, family Pteridophyta.) These plants have a wide distribution, but were far more numerous in Palaeozoic times, especially the Carboniferous period (363-290 million years ago), when members of the group were large trees. The species that exist now are all small in size.
