3. Pang. Common on the Chalk, as at Pangbourn, Moulsford, &c. 



4. Kenuet. Common near Beedon, Rev. W, M. Rogers. Common on 



the Chalk, ascending to the top of Walbvny Camp, 957 feet, 



5. Loddon. Near Wellington Coll., Tufnail. Very common near 



Marlow and in the fields about Hurley, Wargrave, and near 

 Maidenhead. It also occurs near the Blackwater at Jouldern'.s 

 Ford, and by the Thames near Bray. 

 Occasionally plants of glabrous S. Cucuhalus, which in itself has 

 a wide range of variability, are found with the var. imheruJa, so that 

 soil is not the only cause of the development of pubescence. 

 S. Cucuhalus occurs in all the bordering counties.

Casual. Included as a native plant in Britten's Contributions, 1871, on the 

 authority of Mr. H. Boswell, but he tells me that he only found a single 

 specimen in cultivated ground near Newbury in 1858, 1 believe in garden 

 ground near the railway, where a great number of casuals are found. 

 It has no claim to be considered native in Berkshire, and is only of 

 casual occurrence in the bordering counties of Hants, Surrey, and Oxford.

introduced there it is rather dif&cult to suggest.
