Monocotyledons. The Grass 

 Family. We are all familiar 

 with the narrow parallel-veined 

 leaf of the grasses. The stems 

 are usually round and the 

 flowers are borne in structures 

 called spikelets. The flowers 

 have three stamens and a 

 single pistil, which produces 

 one seed. The one-seeded fruit 

 is called a grain. Examples of 

 grasses are wheat, rye, timothy, 

 wild grasses, sugar cane, and 

 bamboo. The sedges, near 

 relatives of the grasses, have un- 

 jointed, triangular stems, while 

 grass stems are always jointed. 



The Palm Family . The palm 

 is known from other mono- 

 cotyledons because it usually 

 has a woody stem. There are 

 about 1200 species of palms in 

 the world. Though mostly 

 inhabitants of the tropics, 

 there are a few species found 

 in the southern part of this 

 country. 



The Lily Family . The mem- 

 bers of this family are known 

 to most of us. Hyacinths, 

 tulips, lily-of- the- valley, as well 

 as the tiger lily and other 

 lilies, are members of this 

 family. Several food plants, 

 as asparagus and onions, be- 

 long in this group. They have 

 the typical liliaceous flower
