I know that Marsh Clubmoss also grows on the site. How can I tell the difference?

Huperzia selago

Marsh clubmoss has creeping stems with occasional upright unbranched vertical stems that bear the small fertile cones with sporangia at the base of the toothed leaves. Fir clubmoss has shoots almost erect and is normally branched. Its fertile leaves are untoothed and are not grouped together in a cone structure at the top of the stem but alternate with sterile leaves in groups up the stem. It also often bears small rather flat plantlets at the top of the stem replacing the normal leaves and allow vegetative reproduction to take place.
