A number of plants obtained from Mr. David Haughs, of the Honolulu Botanical 
Gardens, were introduced into Guam by the writer. They grew well and were left 
in a flourishing condition, In Honolulu beautiful hedges are made of this Phyllan-

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