 Mortimer, F. Ttifnail. Greenham. Burghfield. A plant, which 

 is probably a hybrid with R. leucostachys, occurs at Mortimer.

 hurst and near Hurst. 

 The plant from Beedon, which was named var. fasciciilatus by Prof. 

 Babington in Journ. Bot. (1888 156, was probably only a form of 

 dumetorum. 



Plants which, I think, are hybrids of R. dumetorum with caeshis, with 

 corylifolius, with leucosfachys, and with ulmifoHus occur. 



The brambles Avhich occur in our clay soils are almost limited to 

 R. caesius, R. corylifolius, R. dumetorum, R. ulmifolius, and R. leucostachy^. 

 R. dumetorum occurs in all the bordering counties.
