ID by Colin.
Was excited to find this species. Not very good with ferns or their allies but I think this is L. clavatum.
I should have gotten a picture of the stem. Not sure it can be identified with the photo taken.
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.
