Members of this genus are characterized as flowerless, terrestrial or epiphytic plants with small needle-like or scale-like leaves, covering stem and branches. All Selaginella leaves have a tiny, tongue-like structure, the ligule, on the upper surface near the base.

All the species have their sporangia in cones. Probable relatives of the living Selaginellaceae were very important components of the Upper Carboniferous coal-measure forests (Lepidodendrales), and many were large trees.
