Description: Brief description of this family of terrestrial or epiphytic homosporous, protostelic vascular plants comprising about half a dozen genera and 300 species with images of three species.
Non-Flowering Plant Families, UH Botany Lycopodiophyta (Microphyllophyta). The Lycopodiaceae are terrestrial or epiphytic homosporous, protostelic vascular plants comprising about half a dozen genera and 300 species. The free-living sporophytic plant body is basically dichotomously branching, consisting of a rhizome with adventitious roots, and an aerial portion with numerous, closely spaced, mostly spirally disposed microphyllous leaves, each with a single vascular trace. Eusporagia are found on the upper surface of the microphylls, either in unmodified shoot axes or in compact strobili. The independent gametophytes are bisexual, and are either irregularly lobed photosynthetic masses, or subterranean, branching structures that lack chlorophyll and require a fungal symbiont. Multiflagellated sperm produced in an antheridium must travel through a film of water to reach the egg of an archegonium in order to initiate the zygote that may develop into the new sporophyte individual.
