Berberis (Tourn.) L. Berberidaceae. 160 sp. S. Am. B. vulgaris L. 

 (barberry) Brit. Shrubs. Two sections. In i, Mahonia (Nutt.), 

 the 1. are pinnate; many cult, shrubs. In 2, Euberberis, the 1. are 

 simple, but usu. show a joint where the blade meets the petiole, 

 seeming to indicate a derivation from a cpd. 1. There are also 'short' 

 and ' long ' shoots (if. Coniferae) in this , to which B. vulgaris 

 belongs. The latter have their 1. met. into spines (usu. tripartite) ; 

 transitions may often be seen. The former stand in the axils of the 

 spines and bear green 1. and racemes of fls. (afterwards sometimes 

 elongating to ' long ' shoots). The pollination mechanism is in- 

 teresting. The upper surface of the base of each sta. is sensitive to 

 contact, and when it is touched by an insect in search of honey 

 (secreted by the nectaries upon the bases of the inner P 1.) the sta. 

 springs violently upwards, covering the side of the visitor's head 

 with pollen, which it may place on the stigma in the next flr. visited. 

 The fr. is sometimes made into preserves. 



An interesting.point about the common barberry is its connection 

 with the disease known as black rust, which occurs on wheat and 

 other Gramineae. The fungus (Pitccinia graminis or Aecidium 

 berberidis} passes through two alt. stages in its life history, one on 

 the grass, the other on the barberry, so that if there are no barberry 

 plants in a district, it is to a large extent, though by no means 

 absolutely, insured against black rust.
