FLOWERING TREES AND SttRUBS.

which are desirable plants. The genus Philadelphia contains 

 a number of most useful flowering shrubs. I mention specially 

 P. microphyllus, a Western North American dwarf shrub, with 

 small white flowers : it comes in very useful in places where 

 there is not sufficient space for the taller-growing species. M. 

 Lemoine, of Nancy, has raised a number of hybrids between this 

 and P. coronarius, the Mock Orange, and these also are really 

 excellent garden plants. The Rocky Mountain Jamesia americana 

 is w T orth growing : it is a dwarf bush, free flowering, and perfectly 

 hardy. Carpentaria californica, a handsome shrub with large 

 Philadelphus-like llowers, is generally grown against a wall ; it, 

 however, thrives as a bush in the open shrubbery. Of all the 

 Escallonias E. Philippiana is the hardiest in the neighbourhood 

 of London : it is a compact grow r er, and produces an abundance 

 of white flowers. Itea virginica is hardy enough, but likes a 

 strong loamy or clayey soil ; it only grows about a couple of feet in 

 height, and its terminal erect racemes of white flowers are very 

 showy. This plant, too, is worth growing if only for the beau- 

 tiful autumnal tints assumed by the decaying leaves.
