watering must be given without wetting, and thereby 

 injuring, the foliage. The pots should be plunged in the 

 cutting case, or in any bottom heat of about 70deg. or 

 SOdeg., and covered with a bell glass. All that is then 

 necessary is to keep them moist and shady during sunshine, 

 until they are rooted, which, as a rule, is effected in three 

 weeks' time. When well established, they may be removed 

 from the case, gradually hardened off, and finally potted 

 singly into small thumb pots.

 The garden hybrids are very handsome. A selection is 



given below :

 freely branching habit, and strong constitution ; D AZZLKR,* habit
