The antheridium develops from a superficial antheridial initial which divides transversely and produced an outer cell and a basal cell. The outer cell divides further by successive transverse divisions to form a linear filament of 2 to 4 cells. Basal cells form the stalk of the antheridium (Fig. 4 A-C).
The ter¬minal apical cell of the filament divides by two vertical intersecting walls so the apical cell with two cutting faces formed (Fig. 4D).
Apical cell cuts off cells in two rows. Each young segment of the upper 3 to 4 cells now divides by a vertically diagonal wall to form two unequal cells (Fig. 4E-F).
