Lycopodium is part of a group of plants known as fern allies. They are primarily non-flowering plants characterized by their extensively branched structure, featuring small and simple, needle-like leaves that densely cover the branches and stem. In contrast, Equisetum, commonly referred to as horsetail or snake grass, resembles a horse's tail and is the sole surviving genus within the Equisetaceae family, known for vascular plants that reproduce using spores instead of seeds.
