Running-Clubmoss

Lycopodium clavatum - Running-Clubmoss has erect, leafy stems arising at intervals from horizontal (also leafy) stems spreading along the surface, or beneath fallen leaves, but not beneath the soil. The leaves spread from several sides of the vertical stem, giving a round cross-section to the branches (i.e. the branches are not conspicuously flattened in appearance. Spores are produced in sporangia located only in specialized "strobili" or cone-like structures at the ends of the leafy vertical stems. L. clavatum is separated from other species in this group by having a narrow elongated stalk between the leafy stem and the strobilus, and by the lack of conspicuous narrowings along the vertical stems, called annular (or annual) constrictions. L. clavatum has elongate, hairlike tips to each leaf, unlike the leaves of all our other Lycopodium species.
