Common Ground-Pine

The common ground pine, <em>Dendrolycopodium obscurum</em>, is a vascular plant belonging to the family Lycopodiaceae, a lineage of ancient clubmosses. This species is typically found across North America, with its known range encompassing Canada and the United States. As a lycophyte, <em>Dendrolycopodium obscurum</em> represents a deeply divergent lineage among land plants, distinct from mosses and ferns. The species typically grows in moist forested habitats, particularly in coniferous and mixed woodlands where humidity and leaf litter provide suitable conditions for its growth. Its upright, tree-like sporophylls give it the common name ground pine. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.
