 condensed from (in. 4fi, p. 300; This species enjoys an 

 abnndancf of light and sun-heat, and needs to have its 

 wimmI thoroughly ripened in the autumn to insure a dis- 

 play of bloom. If small plants can be procured they 

 sh<mhl be nipped about February 1, If a few leaves are 

 reni<t\'ed, after the top is pinched out, slioots will start 

 im)r(^ evenly. After pinching, the plants are ]>ut into 

 considerably largiT pots, a I'eaty soil lieing generally 

 used and good drainage given. They shouhl be given a
