Hornworts (Anthocerotae) are bryophytes which have flattened thallus that produces hornlike structures called as sporophytes. e.g. Anthoceros. In liverworts, asexual reproduction occurs by fragmentation of thalli or with the help of specialized structures called as gemmae. These are green, multicellular, asexual buds which grow in receptacles called gemma cup located on thalli. These gemmae detach from the thallus and germinate to form new individual.
