These unite in making the seed, or the in connection with the formation of the seed a newgrowth of the outer coat, or integument, of the ovule occurs,forming the outer coat of the seed, known as the testa, whilethe inner integument is absorbed. In some cases the innerintegument of the ovule also forms a new growth, making aninner coat of the seed (rosaceae). In still other cas
