Clubmoss (Lycopodium sp.) spores Clubmoss (Lycopodium sp.) with strobili Huperzia with sporangia

Selaginella deflexa (left), small club moss. A 3-lobed megasporangium is clearly visible inside the bend in the fertile axis. The smooth, unlobed sporangia are microsporangia. The megasporangia contain 4 large spores in a tetrahedral configuration while the microsporangia contain hundreds of tiny microspores.
