 most other plants whi<'h have oidy one, stays nnder 

 gronnd. In tho Onion it conies np and makes tho 

 first leaf, — a slendei-, thicad-shapi'd one, and in- 

 deo<l it carries np the li<,'lit seed on its sinnmit. In 

 Indian Corn, all the <'arly joints of stem remain so 

 short as not to l»e seen ; althotiijh later it makes Ion <f

47- Number of Cotyledons or Seed-Leaves. TTulian Corn (Fi<r. 46), and all such 



kinds of grain-plants, the Onion, Lilies, and the like, hav»^ only one seed leaf or 

 cotyledon to their embryo ; therefore thoy are called Monocotvlkdonous Pi.ants, 

 and the embryo is called mim<n-nti/U<l<)W)U!< -n. long word, meaning "with one 

 cotyledon."
