The control of antheridial and archegonial formation in some Filicinophytes is quite complex. Prothalli grown in crowded or adverse conditions have restricted growth and antheridia only eventually develop so they become ‘male’. Well grown gametophytes (spaced out) develop archegonia first and then antheridia later, i.e. passing through a ‘female’ stage to the hermaphrodite condition.
