allowed to grow and bloom, because those with the largest 

 and handsomest racemes of flowers may be saved for Labur- 

 nums, and the others may be worked with the different 

 species of Cytisus, some of which are white, others yellow, 

 and many are of different forms and habits ; but all make 

 good standards. Some of them have small racemes of 

 flowers, others bloom all the way along the branches ; some 

 are pendulous, others shrubby and upright; but all very 

 pretty, and worth growing in collection among ornamental 

 shrubs. Most of the hardy kinds may be grown as dwarf 

 shiTibs in any common soil, and are readily increased either 

 by seeds or by layers. The greenhouse species are hand- 

 some shrubs, growing freely in peat and loam, and increased 

 by seeds, by grafting, or by cuttings.
