When it finally comes to rest it withdraws its flagellum, surrounds itself with a membrane, bores through the wall and discharges its thick naked protoplasm into an epidermal cell of the host, where it attaches itself to the nucleus as an amoeboid proto- plast (Fig. 9, 2 to 6). A period of promitotic (or amitotic?), later of mitotic, nuclear division follows, during which the protoplast is sur- rounded by a membrane and develops to a sporangium. At maturity.
