This appears to be the common iriandra form in the county.

H. Hoffmaniana, Sm. appears to be the var. concolor of Andersson, Mon. 

 Salic. 1867, and is, I think, worthy of specific rank. It forms smaller 

 and more compact bushes than the tj^pe, and the leaves are also 

 different, being yellow or green, and of a thinner texture. Syme 

 makes a third variety, S. amygdaUna, Linn. Sp. PI. 1016, Syme, E. B. 

 1. c, t. 1315, which he says differs from the two preceding forms 

 by the young twigs being deeply furrowed. It has larger stipules 

 than the type, and the leaves are glaucous beneath. I have seen it 

 at South Hinksey, Shippon, Wantage, Pangbourn, Wargrave, &c. 

 It is probably the var. discolor, Andersson, 1. e. Buchanan White says 

 that the Linnean S. amygdaUna, if not altogether dubious, is a synonym 

 of <S. triandra. Andersson was of opinion that his discolor in Western 

 Europe was a more truly wild form than the var. concolor. It is less 

 frequent with us. The var. Hoffmaniana (concolor) is extensively planted 

 in our area. 



xS. UNDULATA, Elirh. Beitr. vi. loi, not of Forbes or Schleicher. 



S. lanceolafa, Smith, E. B. t. 1436. S. triandra x alba, E. F. Linton. 

 aS. triandra xviminalis, F. B. White. Syme, E. B. viii. 213, t. 1312. 



To this I refer a willow which I have seen at Kennington, near 

 Radley, and at Wytham. To me it appears to be a hybrid of S. alha 

 and triandra. Dr. F. B. White was rather inclined to refer the 

 Kennington plant to S. Treviranii, Spreng, Pugill. i. 61, than to S. Ian- 

 ceolata. Sm., which is the commoner hybrid, but I fail to recognize the 

 influence of S. viminalis in our plants. The Rev. E. F. Linton has 

 named one of my specimens from Wytham S. lanceolata. 



The aggregate species S. triandra is recorded for all the bordering 

 counties except E. Gloucestershire. 



S. fragilis, Linn. Sp. PI. 1017 (1753). Bedford Willow. 



S. Russelliana, Sm. Fl. Br. 1045. S. fragi'is, var. Russelliana.
