even a frequent species, although widely spread through 

 Britain; nor is it very clear whether 60 or 70 counties 

 might be the nearest census for it. Two principal varieties 

 occur. One (E. brachycarpum, of Leigh ton) with short 

 fruit and leaves broad at the base; the other (E. macro- 

 carpum, of Stephens) with elongated fruit and leaves taper- 

 ing into a narrow base: differences of size being also ob- 

 servable in their flowers. The two, however, are closely 

 connected by intermediate varieties ; and corresponding 

 diversities of leaves and flowers may be frequently seen in 

 other species of the genus.
