Any of about 200 species of primitive vascular plants that constitute the genus Lycopodium (order Lycopodiales), mainly native to tropical mountains but also common in northern forests of both hemispheres.

Representative species include running pine, or stag's horn moss ( L. clavatum ), ground cedar \(L. complanatum 2018; flabelliforme'), shining club moss ( L. lucidulum ), fir club moss ( L. selago ), ground pine ( L. obscurum ), and alpine club moss ( L. alpinum ).
