BAKBEBKY. - 27 



bearing 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 

 upon 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, &c. 



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, VUlgariS alba, White fruited. Not very productive, 

 and not so vigorous a grower as the original. 



B. Vlllgaris aspcrma* 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, Ylllgaris 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, JBerberis 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. Vlllgaris purpurea, Purple leaved. Leaves dark 

 purple. On this account it is very ornamental. 



B, Vlllgaris glauca, Leaves pale green and glaucous; 

 not shining. 



B, Vlllgaris longifolia* Leaves longer than in the spe- 

 cies ; otherwise the same.
