 when grafted on the laburnum, stand- 

 ard high. Of all the different species 

 of Cytisus, when grafted standard 

 high, this forms the most graceful 

 tree; and a plant of it covered with "^ZiS^-^^^^^ 

 its [)urple flowers, placed on a lawn, (y ^^/'fl 

 or in a border near a standard of 

 Genista triquetra, covered with its 

 golden yellow flowers, will produce a very striking 

 effect. Plants, in the London nurseries, are 1*. 6r/. each ; 

 grafted standard high, they are from 2s. 6d. to 5s. : at BoUwyller, they 

 are 50 cents each ; and for two years' seedlings, -i francs for 2o.
