30 Description of Plants belonging to the Genus Hoya. 



mediately wanted, cuttings of the branches must be used, 

 for these generally produce shoots the same year in which 

 they are struck, whereas the leaves seldom make any pro- 

 gress, except that of rooting, until the year following, unless 

 under particular circumstances. In propagating by the 

 leaves, the shoot, which is to become the future plant, pro- 

 ceeds from the base of the footstalk, and the leaf itself sub- 

 sequently perishes. When first planted, the leaf should be 

 immersed in the mould less than half its length.
