Observed at Grand Portage State Park, MN
I found this club moss on the edge of the woods near my house. It took me a second to identify it, but once I did, it was clear to see that it was growing all over the edge of the woods. It was very short and hard to see and bright green in color.
The Lycopodiaceae (class Lycopodiopsida, order Lycopodiales) are a family of primitive nonvascular plants, including all of the core clubmosses. These plants bear spores on specialized structures at the apex of a shoot; they resemble a tiny battle club, from which the common name derives. They are non-flowering and do not produce seeds.
