lycopode en massue

<em>Lycopodium clavatum</em>, commonly known as common club moss or running clubmoss, is a primitive vascular plant in the family Lycopodiaceae. This ancient lineage predates seed plants and is distributed across a remarkably wide geographic range, including Africa, Asia, Europe, North America, Oceania, and South America. It typically grows in heathlands, moorlands, boreal forests, and alpine meadows, often forming extensive creeping mats along the ground. The species reproduces via spores produced in distinctive club-shaped strobili, from which it derives its common name. <em>Lycopodium clavatum</em> favors acidic, well-drained soils in open or semi-shaded habitats. Its spores have historically been used in pyrotechnics and as a coating for pills. Biological traits of this species remain poorly documented in the scientific literature.
