ARBORETUM ET FRUTICETUM BRITANNICUM. 



Spec. Char., Sfc. 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 7 ft. 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 occu[)ied in extracting the honey. 

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

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

 as high as 13 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. 



^ C. a. 2 incarnahis 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.
