condition which, though probably of rare, is not of unknown 

 occurrence. "Whilst in most of Mr. Briggs's specimens the twigs 

 are rather slender and reddish in colour, the catkins vary both 

 in size and direction. Some of the specimens are rather like 

 No. 1955 of Billot's ' Exsiccata,' published as Salts fragilis, but 

 which agrees with the description in G-renier and GrodronV Flore 

 de France' of S.fragilis var. pendula {S. pendula, Ser.), which 

 Wimmer says is a form of his var. vestita of S. viridis. 



In Eoxburghshire, Mr. A. Brotherston has found a few trees 

 which may be described as having the leaves of S. alba, and the 

 capsules, except that the pedicel is short, of S.fragilis. He also 

 finds what seems to be the <$ of the same, and I have seen a 

 similar plant from Brandon, Warwickshire (T. Kirlc). These 

 would be called var. albescens. 



In Perthshire, S. viridis occurs in several places on the banks 

 of the Tay, along with S.fragilis and S. alba. In one place the 

 trees have evidently been planted, but have almost certainly been 

 brought from some other and adjacent part of the banks. They 

 are all $ and, whilst distinctly S. viridis, closely approach S. 

 fragilis in character. In another locality a single tree grows. 

 This is much older than those in the above-mentioned station, 

 and is, in all probability, self-sown. It is in many ways like fif. 

 alba, from which, however, the more glabrous leaves and distinctly 

 though shortly stalked capsules at once distinguish it. From 

 some other stations I have as yet seen leaf-examples only. 



From the erroneous conceptions of Smith's Russelliana by 

 many salicologists, it is not to be wondered at that the citations 

 of descriptions and figures, as regards both S. viridis and S.fra- 

 gilis, are in many cases wrong. Andersson, for example, cites 

 Sal. Wob. t. 27, and Wimmer both that and t. 29 and t. 30 under 

 S.fragilis, L. ; but t. 27 is viridis, t. 29 is decipiens, and t. 30 is 

 fragilis. Under S. fragilis-alba {—viridis, Fr.) Wimmer refers 

 to Sal. Wob. t. 28 {Russelliana), which represents fragilis, and to 

 t. 19 {rnontana), which, from the description " germens nearly 

 sessile," as well as from the figure, is viridis. The references to 

 Smith's descriptions and figures, and to those writers who have 

 followed Smith, are likewise all wrong, though, while giving 

 " Russelliana, Sm.," as a synonym of the fragilis-alba hybrid, 

 both Wimmer and Andersson confessed that in their opinion 

 the identity of Russelliana, Sm., was altogether doubtful. It * s 

 evident, therefore, that the synonymy and citations — both British
