able to consult Macgilli\Tay's description {Udin. New Phil. 

 Jour., vol. ix. p. 335), and that author's own specimens are 

 too poor and too near S. Myrsinites. 



Sheet 378. — S. Sadleri, Syme. After a long study of *S'. 

 Sadleri, in both a living and a dried condition, I think that 

 there can be no doubt but that it is a hybrid of S. lanata, 

 and that the other parent is probably >S^. reticulata. Since it 

 has been in cultivation it has developed some characters not, 

 or scarcely, shown by the original wild specimens. 



Sheet 363. — S. herhacea (Loch Kandor, 1830, Greville). 

 Eemarkable, in that the ovary has several lines of hairs and 

 the style is bifid to the base. I have found, however, nearly 

 similar forms in Perthshire. 



Sheet 327. — " Salix vacciniifolia, Craig Chailleach, Perth- 

 shire, Dr Hooker." The specimen marked No. 1 is, I sus- 

 pect, one of the series of willows which I have named S. 

 simulatrix (Arhicscida x herhacea). Though the specimen is 

 in too young a condition to afford much evidence, yet, when 

 taken in conjunction with other specimens from neighbouring 

 hills, the affinity with both of the supposed parents is suffi- 

 ciently clear. 



Sheet 377. — " Salia:, , Clova Mountains, 1824 (Loch 



Brandy)," Gre^^lle. " Possibly a pilose state of S. retictdata" 

 Leefe. Though the four small specimens on this sheet are 

 without flowers, they so evidently belong to a hybrid be- 

 tween S. retictdata and S. Lappomim that I have ventured 

 to give them a name — S. sihi/llina. It is to be hoped that 

 the plant will be found again. 



Although there are no specimens in the Herbarium, a 

 willow cultivated in the Gardens, and for specimens of which 

 I am indebted to Mr Lindsay, may be included in these 

 notes. The plants were originally found by the late Pro- 

 fessor Dickson and the late Mr Sadler on Ben Challum, 

 Perthshire ; and from the same hill I have seen more recent 

 specimens, collected by Messrs Groves. This willow is 

 evidently a hybrid between >S'. herhacea and S. aurita, and 

 as such I have described it under the name S. margarita.
