1. 112, Saluv coriacea, represents this hybrid. From the plate alone 

 no certain conclusion could be derived ; but specimens received 

 from Kew Gardens, and others published by Leefe (under S. 

 nigricans), can scarcely be satisfactorily placed otherwise than 

 here, though they do not exhibit the best form of the hybrid. 

 In the plate both <5 and $ flowers are shown, but I have seen 

 the 2 only. The flowers in the specimens show a more marked re- 

 lationship with aurita than they do in the plate. If I am right 

 in referring Forbes's plant, S. coriacea (Schleich.), Forbes, must 

 be the name of the hybrid ; otherwise it will have to be called 

 S. aurita-nigricans, Heidenr. 



Like its close ally S. strepida, S. coriacea shows considerable 

 variation. From that species the form of the leaves, recalling 

 aurita rather than cinerea, the usually smaller and narrower $ 

 catkins, the shape and smaller size of the capsules, and frequently 

 the colour of the scales are characteristic points which will serve 

 to distinguish coriacea. So far, however, as our specimens go, 

 it is more likely to be passed over as a form of nigricans, from 

 which, however, careful examination will show its distinctness.

nigricans and aurita amongst its parents. Eroru certain points, 

 however, in which it resembles the willow (from the same locality) 

 already referred to as S. tephrocarpa, Wimm., I am inclined to 

 suspect that it also includes S. Oaprea and is a hybrid of that 

 species with 8. coriacea.

There is a divergence of opinion amongst botanists as to the 

 situation of S. Arbuscula. Many, including the British, think 

 that it should be associated with S. Myrsinites, &c. ; but Anders-
