grows, until it can provide for itself; the seed-coats to protect it, especially after it 

 is shed ; the seed-vessel, to protect it and to nourish it while forming ; the stamens 

 and pistil, to originate it. 



2 GO. The embryo consists of its Radicle or original stemlet, from one end of 

 which the root starts, from the other the stem is continued ; also of one or more 

 Cotyledons or Seed-leaves^ and often of a Plumule or bud for continuing the stem 

 upwards. How the embryo grows into a plant, was fully explained at the com- 

 mencement of this book.
