 no other plantation, except larches, would give so quick a return for the 

 trouble and expense of planting.

As an ornamental tree, 5alix vitellina is very striking in the winter season, 

 especially among evergreens. As a shrub, it is not less so, both among ever- 

 green shrubs and deciduous kinds, having the bark of conspicuous colours. 

 In the English garden at Munich, extensive masses of this willow are placed in 

 contrast with masses of the white-barked honeysuckle (Lonicem Xylosteum), 

 the red-barked dogwood (Cornus alba), and the brown-barked spiraea 

 rae'a opulifolia). 



Group vii. 



Extra-European Kinds allied to the Kinds of one or all of the three preceding 

 Groups. Prin. sp. 28. 



Of the willows of Europe Koch has associated the kinds of Mr. Borrer's 

 groups Pentandras, Fragiles, and A'lbae into one group, which he has 

 named Fragiles ; and he has pointed out and described, as extra-European 

 kinds belonging to it, S. occidentalis Bosc, S. nigra Mu/tl., S. babylonica L., 

 S. octandra Sieber, and S. Humboldtfawa Willd. Mr. Borrer has included 

 S. babylonica L. in his group Fragiles. The rest are here collected in a 

 group by themselves, to which is added S. /igustrina Michx. jun., from the 

 notice by Mr. Forbes, and also by Michaux, that it is similar to S. nigra.
