PIGWEED FAMILY. Chenopodiaceac. 



A pretty desert variety of Wild Buck* 

 Wild Buckwheat .'.,. f 



Eriogonum wheat. The pale downy stem is from 



racemdsum one to two feet tall, rather stout, with two 



Pink, white O r three erect branches at the top, and the 



leaves are all from the base, gray-green in 

 color and covered with close white down 

 on the under side. The small white and pink flowers are 

 clustered along the branches in small heads, with reddish 

 involucres, forming a spike about three inches long. The 

 whole effect of the plant is curiously pale, but quite pretty. 

 It grows plentifully on the rim of the Grand Canyon. 



There are many kinds of Polygonum, East and West, 

 many of them insignificant, some aquatic, some woody at 

 base, with alternate leaves, and sheathing stipules; the 

 sepals four or five; the stamens five to nine; the style with 

 two or three branches and round-top stigmas. The name 

 is from the Greek, meaning "many knees," in allusion to 

 the swollen joints of some kinds. 



This is about two feet tall, very pretty 

 Knot-weed 



Alpine Smartweed and rather conspicuous, and the general 

 Polygonum effect of the smooth stem and sheathing, 



bistoriotdes green leaves is somewhat grasslike. The 



flowers, which are small and cream-white, 

 West with pretty stamens and pinkish bracts, 



grow in close, roundish, pointed heads, an 

 inch or two long, at the tips of the stalks. The buds are 

 pink and the heads in which the flowers have not yet come 

 out look as if they were made of pink beads. This is an 

 attractive plant, growing among the tall grasses in moun- 

 tain meadows, and smells deliciously of honey.
