 Distributed more or less over the chalk downs of the county. The 

 whole plant is clothed with a shaggy, deciduous cottony web, which 

 is most dense and permanent on the backs of the leaves, and is 

 subject to much variation in size, also in the number of flowers. 

 There are specimens in the Sherardian Herbarium with 1, 2, 3, and 

 6 flowers on each, and varying in height from 3 to 7 or 8 inches.

 globular heads. Dr. Prior informs us that the plant is called dock 

 as many others are, from its large leaves, but why bur is uncertain.
