Lycopodiaceae, commonly known as clubmosses, is a family of vascular plants that belong to the division Lycopodiophyta. These plants are characterized by their small, scale-like leaves and spore-producing structures called strobili, which resemble tiny cones. Clubmosses are primarily found in moist, shaded environments and can be seen in forests and woodlands. This family includes several genera, with Lycopodium being the most well-known. Clubmosses are ancient plants, with a history dating back over 300 million years, making them some of the oldest living lineages of vascular plants. They play a role in their ecosystems by providing ground cover and contributing to soil stability.
