What are some examples of lycophytes?

Some examples of lycophytes include clubmosses (such as Lycopodium and Selaginella), quillworts (Isoetes), and the fossilized tree-like forms known as Lepidodendron. These plants are characterized by their vascular tissue and small, scale-like leaves. Lycophytes are among the oldest groups of vascular plants, with a history dating back over 400 million years. They typically thrive in moist, shaded environments.
