SCHEMATIC LIFE CYCLE; Anthoceros is a genus of hornworts in the family Anthocerotaceae. Mosses can be distinguished from other bryophytes because they have foliose The genus is global in its distribution. The genus is global in its distribution. VEGETATIVE REPRODUCTION • It takes place by the following methods: • Progressive death and decay of thallus. Gametophytes are monoecious and thus individual plants bear both male antheridia (E) and female archegonia. They perform photosynthesis.
