This gallery consists of the clubmosses and the horsetails. Clubmosses (Class Lycopodiopsida) are thought to have been the earliest group of plants to evolve vascular systems. The class has few species and few, but very interesting, human uses.
Horsetails (Class Sphenophyta) have even fewer species with just one remaining genus, Equisetum, worldwide. Ecologically, horsetails play important roles in nutrient cycling, especially in aquatic systems.
All the images of non-flowering plants were photographed in the Upper Peninsula.
