BERBERIDACEAE 



and south into Mexico, It is so similar to B. fremo nti i that it 

 can be used in similar sites and though its susceptibility to grain 

 rust has not been determined, it should be tentatively classed as 

 susceptible . 



Berbe r is t rif oliolata , Three-leaved Algerita, is the common 

 Algerita of western Texas. In Wooton & Standley's Flora of New 

 Mexico it is reported as occurring in western Texas, southern New 

 Mexico and southern Arizona. The writer has never observed it in 

 southern Arizona, Commonly this species is a lower bush than the 

 above-mentioned Algeritas but it is quite similar otherwise. It 

 can be readily distinguished from the others in having three leaf- 

 lets to the leaf instead of five or more. It is listed among the 

 barberries susceptible to grain rust. Its fruit is excellent for 

 .jelly. 



Berber is f end.l eri is a Barberry which is very different in 

 habit and general appearance to the Algeritas. It is a slender 

 shrub seldom more than three feet high with numerous horizontal 

 roots which sprout readily. The species is thicket-f orming. The 

 plants are thorny (not just the leaves), and the fruits are bright 

 red. It ranges in the mountains of Colorado and northern New 

 Mexico. As an erosion control plant it is ideal except that it 

 requires a relatively high altitude and considerable moisture. The 

 chief objection to it is its high susceptibility to grain rust and 

 the fact that it cannot be expected to grow in regions where it 

 will not be a menace to grain. 



Berber is vulg aris is the common Barberry of cultivation. 

 It is not a native of the west but has been planted extensively and 

 more extensively eradicated to prevent the spread of grain rust. 

 Hundreds of thousands of dollars were spent to get rid of this 

 pest when Congress was much more Scotch, with appropriation than it 

 is today. It goes without saying that its use is not to be recom- 

 mended. 



Berberis thu nbergii, the Japanese Barberry, closely resembles 

 B, vulgar is. It has been quite extensively Introduced throughout 

 the United States as a substitute for B, vulgaris. It is not sus- 

 susceptible to grain rust but it is unsuited to the southwest as an 

 erosion control plant as it is not drought resistant not suitable 

 to very warm climates. 



Berberi s is often erroneously called Oregon Grace. 



It is a handsome, very low shrub with large pinnate spiny-edged 

 leaves, bright yellow blossoms and clusters of black fruits which 

 make delicious jellv. It grows throughout our range but only in
