what are the club shaped structure in lycopodium called?
fertile stems
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.
