Fan Clubmoss

Fan Clubmoss
Lycopodium digitatum

Ah, the clubmosses, which aren't a moss at all, but rather a primitive vascular plant. These plants have been roaming the earth for some time now, over 300 million years.  The plants of old were monstrous, as large as oak trees, and the dominant plants of the era.  Coal beds were formed by these and other spore-bearing plants.

Fun Fact: The spores of this plant are high in oil and are quite flammable, once called "lycopodium powder".  When tossed in a flame, they ignite briefly with a bright flame and have historically been used as a source of light for photographer's flashes, as well as many other uses that people have had over the years for flashy flames.  Now I've got to go out and collect some, for research purposes.
