THE AMERICAN BOTANIST 



flowering shrub. The blue spiraea (Caryopteris inastacantha) 

 does not begin to open its blossoms until September but it con- 

 tinues in bloom for a month or more. The plant is not a spiraea, 

 being more nearly allied to the chaste tree. Its appearance, 

 however, is much like a low spiraea, which accounts for the 

 dealer's name for it. It is also known as Chinese beardwort. 



This phase of the subject should not be left without some 

 mention of the bush clover (Desmodmin penduUfloniin ) . It 

 is neither a bush nor a clover, though it simulates both close 

 enough to deserve its common name. In late September it is 

 literally covered with racemes of pink pea-like flowers which 

 make it very conspicuous. It dies to the ground in winter, 

 though very shrub-like in appearance. 



Coming back to shrubs that will give additional beauty to 

 our shrubberies in spring, we find a wealth of material from 

 which tO' choose, exclusive' of the popular favorites. The pearl 

 bush {Exochorda grandiflora) is an excellent species for vary- 

 ing the monotony of viburnums, syringas, and deutzias. As its 

 common name indicates, the flowers are pearly white and are 

 produced in abundance on the ends of the branches. The globe 

 flower (Kerria Japonica) with flowers like small yellow roses 

 is an interesting" addition to the border, not alone because of its 

 flowers but also' on account of its stems which are covered with 

 green bark that gives a touch of vitality to the shrubbery even 

 in winter. In autumn it frequently produces a second crop of 

 flowers. Another species, which for want of a better name is 

 known as the white kerria (Rhodotypos kerrioides) has rather 

 larger white flowers that somewhat resemble those of the black- 

 berry. The shrub forms a compact green head that even chw 

 weather seems nearly powerless to injure. 



The laburnum or golden chain (Cytissiis lahurnuin) is 

 better known in the Old World than it is here, but it is one of 

 the most attractive of plants. At the blooming season it is 

 thickly set with long drooping racemes of yellow flowers very
