Did you know?
Clubmosses are "primitive" plants, living relics of some of the earliest vascular plants. There are abundant fossils of tree-like lycopods or clubmosses, which are sometimes depicted in museum displays of dinosaurs. Such specimens are closely related to the smaller clubmosses still found today.

State Ranking Justification [-]
There are only 3 existing occurrences (2 from Long Island and 1 from the Adirondacks) and 3 historical occurrences (all from Long Island).
