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).
