Buds smaller, longer, and appressed ; otherwise like 

 those of S. caprea. 



Leaves narrow, lanceolate-acuminate, finely serrate. 

 Shining and green above (with a few silky hairs), glaucous 

 beneath. Catkins cylindrical and stalked, otherwise 

 with a general resemblance to those of other Willows. 

 Flowers in spring. 



Fruit longer and narrower than 8. caprea, but the 

 seeds cannot be readily distinguished, nor can the wood 

 except that the heart is browner. 



17. CRACK WILLOW. 

 Salix fragilis (L.). Salicinese. 



A tree, very like S. alba, but the foliage more 

 decidedly green, and the glandular points of the teeth 

 more distinct. The leaves are also often broader and 

 the catkins somewhat looser. 



Wood like that of S. alba. Branches snap easily at 

 the joints in spring. 



18. OSIER WILLOW. 

 Salix viminalis (L.). SalicinesD. 



Shrub, with long flexible, twiggy branches (occasion- 

 ally a small tree). The twigs smooth, olive to chestnut 

 brown. Grows in wet places. 



Buds very small. Leaves very long and narrow, 

 lanceolate, with copious silky hairs beneath. Margins 

 undulated, and nearly or quite entire. Stipules minute
