Grafting of Flower-buds on Syringa vulgaris. By X. [Bull, 

 d. B. Soc. Tosc. Ort. 4, p. 109 ; April 1901).— A cheap and easy method 

 of obtaining forced flowers of Lilac every winter consists in grafting 

 strong shoots bearing latent flower-buds, 15-20 cm. in length, taken from 

 shrubs growing in the open, on to the ends of branches of plants in the 

 stove which have already flowered, the graft to be inserted between the 

 wood and cortex of the subject. In ten to twelve days the buds begin to burst, 

 and flowering takes place after twenty days. The inconvenient part of this 

 method is the longer time which the forcing takes, which would hardly 

 suit private growers with a limited number of plants. But in the article 

 there is another method of grafting mentioned which would seem to 

 obviate this. — TF. C. W.
