The antheridiophore is the reproductive branch bearing the antheridia. The antheridiophore is differentiated into long stalk and a terminal disc. The stalk is about 1-3cm in length having the dorsiventral surface. The disc of the antheridiophore is eight lobed; the growing points are situated at the apex of each lobe. The upper part of antheridiophore has air chambers alternating with the antheridial chambers. The air chamber is triangular in shape and it possesses the assimilatory filaments which are capable of photosynthesis, whereas the antheridial chamber consists only the antheridia and is formed in acropetal succession in rows. That is older antheridia are formed at the center and the younger ones towards the margins.
