Anthoceropsida:

  • Members of Anthoceropsida are commonly called as Hornworts because their sporophyte emerges out of the gametophyte in the form of an elongated horn-like structure.
  • The gametophyte is dorsiventral with unicellular rhizoids but without scales. 
  • Thallus of these bryophytes is generally associated with blue-green algae such as Nostoc.
  • Vegetative reproduction occurs through fragmentation.
  • Antheridia and Archegonia are formed singly or in groups on the dorsal side in special chambers.
  • Sporophyte has foot, intercalary meristematic zone and capsule. 
  • Sporophyte is partially parasitic on gametophyte
  • Capsule possess columella and Pseudoelaters.
