The Anthocerotophyta or Anthocerophyta are more commonly known as the hornworts. These are thought to be one of the oldest extant groups of land plants. Hornworts consist of a flattened thallus with the gametangia produced along the midline of the thallus, each thallus able to produce several sporophytes.
