are rough and convex on the outside, and hollowed out into a cup on 

 the inner face. 



In waste and cultivated places ; a very common weed all over Eu- 

 rope and Russian Asia, and introduced into North America and other 

 countries. Yery abundant in Britain. Fl. the whole season. It varies 

 in the shape of the sepals, and the size and colour of the corolla, and 

 has been divided into three more or less marked varieties or races : 

 — V. agrestis, with oblong sepals, and white or pink flowers ; V. polita, 

 with ovate sepals, and larger blue flowers ; V. opaca, with spathulate 

 sepals and fewer seeds ; but none of these characters have sufficient 

 constancy to justify their maintenance as distinct species.

 (Fig. 755.) 



(Eng. Bot. Suppl. t. 2769.) 



This closely resembles the procumbent 

 V., but is much larger in all its parts ; 

 the pedicels are longer, the flowers 

 larger, of a bright blue, and the lobes of 

 the capsule are broad and divaricate, so 

 that the whole capsule when ripe is 

 about 4 lines broad and only 2 long. 



A weed of cultivation, like the other 

 annual species, but much more abun- 

 dant in southern Europe and central Asia 

 than in central or northern Europe. Oc- 

 curs rather frequently in England, south- 

 ern Scotland, and southern Ireland, but 

 probably introduced with Clover or other 



seeds. FL all summer.

14. Wall Veronica. Veronica arvensis, Linn. (Fig. 756.) 



(Eng. Bot. t. 734.) 



A little, hairy annual, seldom 6 inches high, and often much smaller ; 

 the stems sometimes erect and simple, sometimes diffuse and branching 

 at the base. Leaves almost sessile, opposite, ovate, and toothed, but 

 not cut ; the upper floral ones small, alternate, lanceolate, and en-
