ARBORETUM ET FRUTICETUM BRITANNICUM. 



Spec. Char., $c. Branches terete, twiggy. Leaves simple, 



and trifoliolate, sessile. Leaflets linear-oblong, and silky. 



Flowers in fascicles, disposed in long racemes. Legume 



2-seeded, very villous. (Don's Mill.) An upright shrub ; 



evergreen, from the colour of its numerous straight parallel 



young shoots. Portugal and the Levant. Height 5 ft. 



to 7ft. Introduced in 1752. Flowers white; May and 



June. Legume brown ; ripe in August. 



A very handsome shrub, more especially when covered 



with its white flowers in May, and when surrounded by 



hundreds of bees, busily occupied in extracting the honey. 



In good soil, it is of very rapid growth, attaining the height 



of 5 or 6 feet in 3 or 4 years ; and, in 6 or 8 years, growing 



as high as 15 or even 20 feet, if in a sheltered situation. 



Placed by itself on a lawn, it forms a singularly ornamental 



plant, even when not in flower, by the varied disposition 



and tufting of its twiggy thread-like branches. When in 



flower, it is one of the finest ornaments of the garden. 



Trained to a single stem, its effect is increased ; and, grafted 



on the laburnum, a common practice about Paris, it forms 



a very remarkable combination of beauty and singularity. 



Plants are easily raised from seeds. 



Variety. 



Sfc C. a. 2 incarnatus has flesh-coloured flowers, or flowers very slightly 

 tinged with reddish purple. This variety was introduced in 1818; 

 and reproduces itself from seeds, but it varies much in the quantity 

 of colour in the flowers.
