<P> Lycopodium ( from Greek lukos , wolf and podion , diminutive of pous , foot ) is a genus of clubmosses , also known as ground pines or creeping cedar , in the family Lycopodiaceae , a family of fern - allies ( see Pteridophyta ) . They are flowerless , vascular , terrestrial or epiphytic plants , with widely branched , erect , prostrate or creeping stems , with small , simple , needle - like or scale - like leaves that cover the stem and branches thickly . The leaves contain a single , unbranched vascular strand and are microphylls by definition . The kidney - shaped or reniform spore - cases ( sporangia ) contain spores of one kind only ( isosporous , homosporous ) and are borne on the upper surface of the leaf blade of specialized leaves ( sporophylls ) arranged in a cone - like strobilus at the end of upright stems . The club - shaped appearance of these fertile stems gives the clubmosses their common name . </P>
