Term:

Crassinucellate ovules

The presence of two or more cell layers between the megasporophyte and the epidermal cells in the early development of the megasporophyte. The megasporophyte develops into the embryo sac which contains the egg that, if fertilized and the conditions are right, will develop into the embryo.
