Salix aurita and S. nigricans, but with the nigricans element re- 

 placed by phylicifolia, and, though a different looking plant from 

 either of the above, shows its hybrid nature in all its parts. 



The c?, though, like the others, near phylicifolia, yet shows, in 

 the small catkins and structure of the leaves, a relationship with 

 aurita ; but if it had not been for the $ examples it would 

 probably have been referred to phylicifolia.

the name S. tephrocarpa. Of this one bush only seems to be 

 known, and, though it grows in the Berlin Botanic Garden, its 

 origin is quite uncertain. 



Both "Wichura and "Wimmer tried in vain to ascertain the 

 parentage of this plant, and the latter finally came to the con- 

 clusion that it might be a hybrid between laurina and cinerea. 



A Willow found by Mr. C. M'Intosh on the banks of the Tay, 

 above Dunkeld, agrees pretty well with the description of S. 

 tephrocarpa ; but I have been able to compare the leaves only, 

 which I owe to the kindness of Herr Hennings, Director of the 

 Berlin Botanic Garden. 



The Berlin and Dunkeld leaf-examples, though not identical, 

 have a fair resemblance to each other, and both show an 

 undoubted relationship with cinerea. In other respects the 

 Dunkeld plant has some affinity with Caprea and, to a slight 

 degree, with phylicifolia. The catkins (?) are large and very 

 handsome, the white capsules contrasting strongly with the 

 conspicuously black scales. The style is very short but present ;
