 many plants, chiefly herbs and most of which are weeds. The

 an entire plant, showing the tap-root and character of the stem (X T V); at 

 the right, a portion of a plant, showing the leaves and flowers about natural

flowers are small and usually greenish. The Spinach and Beets 



are well-known pot herbs of this 

 family, and also from Beets most 

 of our sugar is now obtained. 

 Among the many that are classed 

 as weeds, the Russian Thistle 

 (Fig. 44) is "the most noted one. 

 Belonging to the same order is the 

 Amaranth family, which contains 

 some ornamental plants and a 

 number of common weeds. Of those 

 that are ornamental, the Cocks- 

 comb, Prince's Feather, and Bache- 

 lor's Button, grown in gardens for 

 their highly colored flower clusters, 

 are common ones. The Pigweed, 

 and Tumble weed (Fig. 425), com- 

 mon in gardens, truck patches, 

 and waste places, are the most 

 troublesome weeds of this family. 

 Pink Family (Caryophyllaceae). This family contains many 



species, which are chiefly herbs of the temperate regions. The
