- Homosporous plants with bisexual gametophytes.
- Gametophytes are free living and either photosynthetic or subterranean and dependent on a fungus for nutrition.
- Sporangia are borne on sporophylls. Sporophylls are either grouped in terminal aggrgations to form a strobilus or are distributed in alternating clusters with non sporangium bearing leaves.
- Some species reproduce vegetatively by means of bulbils.
You only need know these plants as club mosses.
