Lycopods, also known as clubmosses, are a group of vascular plants that belong to the family Lycopodiaceae. They are characterized by their small, scale-like leaves and reproduce using spores rather than seeds. Lycopods are among the oldest living plant lineages, with a history dating back over 400 million years. These plants typically grow in moist, shaded environments, such as forests and wetlands. Lycopods can vary in size, with some species being small ground covers while others can reach several feet in height. They play an important role in their ecosystems by providing habitat and contributing to soil health.
