We have examined Dr. Wimmer’s volume chiefly with the view of 
finding what light he throws on our British species. It is curious to 
trace their history in our British Floras. Ray, in his first edition 
(1690) distinguishes 14 species ; this number is raised to 22 by Dil- 
lenius, in the third edition of the * Synopsis" (1724). Hudson reduces 
them to 16 (1778) and Withering returns to Dillenius's number 
(1787). Smith, in his ‘ Flora Britannica,’ enumerates 45, in his 
* English Flora,’ 64; and there are no less than 76 different forms 
figured in * English Botany.’ Lindley, following Koch, brings them 
down to 29; Babington makes them 31; Hooker and Arnott, 38 ; 
and Bentham 15, being one more than the number Ray described 
nearly 180 years ago. 
Wimmer considers that we have 19 true species, besides several 
distinct and distinguishable varieties. But before giving an epitome 
of his conclusions in regard to British species, we must express our 
regret that the author knows nothing of what has been done by Leefe, 
Borrer, and others, and that the ‘ Flora Britannica’ (1800) is the latest 
British Flora with which he is acquainted. Any more recent infor- 
mation is obtained from Forbes’s ‘ Salictum Woburnense,’ a work of 
little critical value. This necessarily detracts from the value of the 
work to British botanists. 
The following nineteen species, enumerated in the order of Babing- 
ton's * Manual, he considers good :— 
1. S. pentandra, Z. 17. S. nigricans, Sm. 
8. 8. fragilis, ID 5. minec L. — S. Weigeli- 
4. S. alba, Z. ana, Wil 
6. S. triandra, Z. 28. S. repens, 
7. S. acutifolia, Willd. = S. prui- 25. S. Arbuscula, L. 
sa, Wendl. 26. S. Lapponum, L 
8. S. purpurea, L. 27. S. lanat: 
10. S. viminalis, Z 28. S. Myrsinites, Z. 
14. S. cinerea, 30. S. reticulata, Z. 
15. S. aurita, Z. 31. S. herbacea, £. 
16. S. Caprea, Z. 
One species he makes a synonym of one of the above, viz. :— 
21. S. angustifolia, Wulf? = S. repens, L. 
And the following species he reduces to hybrid forms, some of which
