and I have no hesitation in referring it to C. Wooclwardii. 

 Thus, assuming the Wilts C. Woodwardii to he simply C. 

 pratensis in a luxuriant state, so also is the Glamorgan- 

 shii'e species. C. Woodwardii differs from ordinary C. 

 pratensis by its much more pinnatifid and lobed leaves, 

 and its heads of flowers often two or three almost close 

 together, not each one single on a long peduncle. The 

 root of C. Woodwardii has fleshy fusiform fibres or 

 tubers ; and it is also stoloniferous, like C. pratensis.

 removal to my garden self-sown plants, precisely like the 

 original, were produced ; and it was from one of these, 

 transplanted to Mr. Dawson Tm'ner's garden at Yarmouth, 

 that the English Botany figure was made. After several 

 years the species disappeared from my garden " (Mr. Bor- 

 rer's 'Notes on the Cybele Britannica '). On another 

 point mentioned in volume second, the different census of 

 C. Jacea and C. nigra in Sweden, Mr. C. Hartman wrote 

 to me thus ; " Om* determination of these two species 

 agrees exactly with the Linnean Herbarium. The latter 

 is unknown in Sweden, while the former is frequent."
