266 BKECK'S BOOK OF FLOWERS. 



Were it not for the ravages of a species of borer, which at- 

 tacks this tree, oftentimes destroying them in a few years, it 

 would be one of the finest in existence for the back-ground of 

 a shrubbery. It is a rapid grower, elegant foliage, fragrant, 

 beautiful flowers, in great profusion, arid very hardy. The 

 blossoms are butterfly or pea-shaped, white, with yellow in the 

 middle, produced in June and July. The insects are so 

 destructive to it, that the trees soon become disfigured, losing 

 their limbs, in consequence of the many perforations made by 

 these troublesome little creatures. 



Robinia viscosa. Clammy-barked Locust. This is a 

 small tree, with large pale-pink flowers. The branches are 

 covered with a gummy substance that is unpleasant to the 

 touch. It looks well with other trees and shrubs. 



Robinia hispida. Kose Acacia. This is a beautiful flow- 

 ering shrub, growing from three to ten feet high, bearing a 

 great profusion of elegant rose-colored flowers, which are pro- 

 duced in dense, pendent racemes. The shrub commences 

 flowering when only two feet high. It has long, rambling 

 roots, which throw up numerous suckers. The branches are 

 thickly clothed with stiff hairs. This is a very desirable 

 species. The foliage resembles the other species. 



Robinia crispa. Crisp-leaved Robina. This is a species 

 or variety we imported last year, with others named below. 

 It has very singularly curious and elegant leaves ; they 

 are compound, like all the others, each leaflet being curiously 

 and uniformly contorted, giving to the foliage a very unique 

 and rich appearance. The others were R. inermis ; tertuoso, 

 the branches all growing in a circular, zigzag style ; mac- 

 rophylla, sophorafolia, dubia, volubilis, elegans and grandi- 

 flora. The style of the leaves in all is the same ; only a few 

 of them flowered, but all will be desirable, no doubt, for orna- 

 ment, if they are not disturbed by the borers. 



The new sorts are propagated by grafting on the common 

 varieties.
