9. strobilus
•У пазусима спорофила се развија по једна
миркоспорангија или макроспорангија
•У микроспорангијама се развија велики број
микроспора, а у макроспарангијама само 4
микроспоре
•Микроспоре даје антеридијални , а макроспора
ахегонијални гаметофит
10. РАЗМНОЖАВАЊЕ
Спорофилни клас је грађен од
осовине за коју су причвршћени
спорофили. Са горње стране
спорофила налази се спорангија.
Споре су обавијене мрежастом
мембраном. Спорангија пуца дуж
једне линије на темену.
