Description
Anthocerotaceae is a family of hornworts, a group of nonvascular plants that are commonly found in damp places. Hornworts are small and inconspicuous, often growing in large colonies. Anthocerotaceae is a monotypic family, with only one genus, Anthoceros, which contains about 200 species.The distinguishing feature of Anthocerotaceae is the horn-like sporophyte that emerges from the gametophyte. The sporophyte is elongated and tapered, resembling a horn or a trumpet. The gametophyte is a flat, ribbon-like structure that lies close to the ground.

Appearance
The gametophyte of Anthoceros is a flat, ribbon-like structure that lies close to the ground. It is often green or yellowish-green in color and can grow up to 10 cm in length. The gametophyte has a simple structure, with a single layer of cells.The sporophyte of Anthoceros is elongated and tapered, resembling a horn or a trumpet. It can grow up to 20 cm in length and is usually green in color. The sporophyte is composed of a foot, a seta, and a capsule. The foot is the base of the sporophyte, which attaches it to the gametophyte. The seta is the stalk of the sporophyte, which elevates the capsule above the gametophyte. The capsule contains the spores, which are dispersed by wind.
