Rnbia tinctoria (Madder). The foliage of this prickly dye plant 

 makes forage of fair quality if cut the second season before the 

 plants have commenced to blossom. 



Saliconiia hcrbacea (Saleratus weed ; samphire ; glasswort). 

 A low, fleshy, leafless herbaceous plant, growing in the borders of 

 salt marshes from Arizona to the Saskatchewan and along the 

 Atlantic coast. It grows on soils too salty or too alkaline to support 

 any other plant. In portions of Arizona and in Utah it is valued 

 highly for winter feed. After frost, stock live almost entirely upon it 

 and "winter fat."

Sarcobdlns wiinculdris (Greasewood. Fig. 29). An erect, 

 scraggy shrub 2 to 8 feet high, with the leafy branches covered by 

 smooth, white bark. It is one of the most common of the shrubs 

 called " greasewood," in the region from Montana to New Mexico 

 and Arizona, and where it is abundant, supplies a considerable part 

 of the winter forage on the ranges. This and the saleratus weed 

 belong to the pigweed family, of which the Australian salt-bush, so 

 widely recommended for culture on alkaline soils, is a member.
