near Folly Bridge, and at Didcot. They are mnch more glabrous than 

 any specimen of true vernalis which I have seen. 



In Sicily the Oxford TRagwoH is known as the Erva de S. Petru. That it 

 was introduced at Oxford from the Botanic Gardens is pretty con- 

 clusively proved by the fact that cultivated specimens are in Bobart's 

 herbarium there. It has now been carried by passing trains over 

 a wide portion of the Great Western System, and is extending rapidly, 

 but I have only records of Bucks and Wilts for the other bordering 

 counties. 



The plate in English Botamj was drawn from a specimen from Oxford 

 sent by Mr. A. B. Lambert in 1799.

Specimens were shown to Mr. J. G. Baker and to Mr. Groves of Florence, 

 who agreed that the above determination was correct. Boissier, in the 

 Flora Orientalis, places this species under S. leucantJiemifolius, Poir. not of 

 Phil. So far as the Oxford and Berkshire plants are concerned, I covild easily 

 believe that they were the ofi'spring of S. vulgaris and S. sqiialidus.
