Ithas fruits like those of flowering plants, with starchy endocarp, butfertilization is accomplished by means of spermatozoids and arche-gonia, corresponding to the male and female elements in animals; thisbrings them closer to the Cryptogams, which are plants destitute ofstamens, pistils, and true seeds.
