BARBERRY. 27 



Dealing portion, opens by slits, but in the Barberry a pair 

 of little doors, or traps, lift up to allow the pollen to fall 

 out. Figure 5 shows two enlarged stamens one closed 

 and the other open. 



The fruit and flowers are not produced at the same time 

 apon the plant, but as a matter of convenience they are 

 both shown on the same branch in the engraving. The 

 fruit is much used for preserves, pickles, jams, &o. 



The thorny character of the plant, with its upright, com- 

 pact growth, makes it a very desirable hedge plant. 



The inner bark of the stem and roots is used in some 

 countries for making a yellow dye. It is also used in Po- 

 land and other portions of the East for tanning purposes. 



The best known varieties of this species are as follows : 



B. vulgar is alba^ White fruited. Not very productive, 

 and not so vigorous a grower as the original. 



B. vulgaris asperma. A variety which produces fruit 

 without seeds. It is not, however, constant, and plants 

 propagated from it will often produce fruit with seeds. 

 This variety has been known and cultivated in England 

 for more than two hundred years, according to Parkinson, 

 Gerarde and other old authors. 



B. vulgar is dulcis. Sweet fruited. Very similar to the 

 species. The fruit is a little larger and not quite so acid, 

 and leaves bright green and shining. 



This variety should not be confounded with the before 

 mentioned species, Berberis dulcis, as the latter has black 

 fruit of the size of a large currant, which is solitary, while 

 that of the former is produced in racemes. 



B. vulgaris purpurea. Purple leaved. Leaves dark 

 purple. On this account it is very ornamental. 



B. vulgaris glauca* Leaves pale green and glaucous; 

 not shining. 



B. vulgaris long-folia. Leaves longer thai: in th ape 

 eies ; otherwise the same.
