L. australianum. Nowhere particularly common - always an interesting one to spot.
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.
