no other plantation, except larches, would give so quick a return for the 
trouble and expense of planting.

As an ornamental tree, Salix 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 (Lonicera Xylésteum), 
the red-barked dogwood (Cérnus alba), and the brown-barked spireea (Spi- 
ree‘a opulifolia).

Of the willows of Europe Koch has associated the kinds of Mr. Borrer’s 
groups Pentandrz, Fragiles, and A‘lbz into one group, which he has 
named Frdagiles ; and he has pointed out and described, as extra-European 
kinds belonging to it, S. occidentalis Bose, S. nigra Muhl., S. babylonica L., 
S. octandra Sieber, and S. Humboldtidna Willd. Mr. Borrer has included 
S. babylénica L. in his group Fragiles. The rest are here collected in a 
group by themselves, to which is added S. digistrina Miche. jun., from the 
notice by Mr. Forbes, and also by Michaux, that it is similar to S, nigra.
