 E. roseum, var. simplex, Lasch, in Linnaea (1831), 492, occurs in 



garden ground at Reading. 



It is somewhat remarkable to find this plant growing to a height of 

 three feet by brook-sides, and to find it in garden ground even in 

 a large town like Readiug, where it is usually seen about the railway 

 station, bearing the smoke without damage. In such situations the 

 plant is, however, less luxuriant. 



E. roseum is recorded for all the bordering counties except Bucks. 



Obs. In the Winch MSS. in the Library of the Linnean Society, E. roseum 

 is entered for Newbury on the authority of Mr. Bicheno, but Mr. H. C.Watson, 

 who used the notes made by Mr. Winch for the New Botanisfs Guide, 

 did not quote this ; possibly he had some doubts of the correctness of the 

 name.
