A nun.iber of i)lants obtained from Mr. David I laughs, ol tlie llonuluki Botanical

 in a flourishing condition. In Honolulu beautiful hedges are made of this Phyllan- 

 thus. They are easily kept in a good compact condition by clipping, and the light 

 pinkish foliage offers a pleasing contrast with darker-leaved shrubs.
