Two varieties of S. fragilis are known to occur in England ; in var. a, 

 Dr. r. B. White says the male catkins are rather dense-flowered, with the 

 staraens conspiciiously longer than the scales. In var. b, which is the true 

 S. Russelliana of Smith, the catkins are lax-flowered, and the stamens are 

 scarcely longer than the scales ; the ovary in var. a is much wider at the 

 base than in var. 6, being ovate-lanceolate, that of var. h being lanceolate- 

 subulate. Our Berkshire plant belongs to the second variety, that is, to 

 true S. Eusselliana, which is the S. fragilis, var. britannica, F. B. White. 



True S. fragilis has been recorded for Surrey, Oxfordshire, and 

 W. Gloucestershire. I have seen it in Bucks, near Marlow, &c. 



Under S. fragilis the Rev. E. F. Linton, in the Lond. Cat. ed. 9, places 

 as a probable hybrid with friandra S. decipiens, Hoffm. Hist. Salic, ii. 

 9, t. 31 (1791), S. fragilis, var. decipiens, Syme, E. B. viii. 206, t. 1307. 

 Fl. Oxf. 271. Dr. F. B. White, in his excellent Revision of the British 

 Willoics in the Journ. Linn. Soc. xxvii. 1,1890) 333-457, considers it to be 

 friandra x fragilis. 



I have seen it near Wytham, Abingdon, &c. 



More recently Messrs. Linton have stated that they are not con- 

 vinced that S. decipiens is S. fragilis x triandra.

Probably to this belongs in part the S. fragilis recorded as ' common 

 by brook-sides at Blewbury, Upton, and in all the villages of the Vales 

 of Berks, and in Mr. Lousley's Orchard, Hampstead Norris, &c.,'
