Internal Structure 4. Heterospory and seed habit, stelar evolution. Selaginella species are creeping or ascendant plants with simple, scale-like leaves (microphylls) on branching stems from which roots also arise. The plants are heterosporous (megaspores and microspores), and have structures called ligules, scale-like outgrowths near the base of the upper surface of each microphyll and sporophyll. The leaves are scaly (Equisetum), small and sessile (e.g Lycopodium), or large, petiolate and compound (Ferns).
