Anthoceros shows affinity with members of Hepaticopsida such as Riccia, Marchantia, etc. in the construction and structure of sex organs and in the apical growth of the thallus.It has affinity with members of Bryopsida i.e. Polytrichum, in the structure such as presence of columella, reduction of sporogenous tissue etc. and development of sporogonium. The spore production from amphithecium resembles the condition of that in Sphagnum. Anthoceros also shows sunken archegonium and development of antheridium from hypodermal initial cell like Pteridophyta. Highly developed sporophyte having photosynthetic tissue, functional stomata, i...

The male reproductive organs are antheridia and the female reproductive organs are called ascogonia. 5. Antheridia and ascogonia are borne at the tips of separate branches. 6. Antheridium is borne at the tip of antheridial branch. It is cylindrical or clavate in shape. 7. Each antheridium is multinucleate. 8. Ascogonium is also present at the tip of the ascogonial branch. It is sub-globose in shape and is multinucleate. 9. The ascocarps are apothecia and develop as a result of fertilization. 10. These are yellowish and saucer shaped. 11.
