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.
The hornworts are an unusual group of plants of which many people are unaware and are so named because of their curious reproductive structures.
