Myoporaceae-Rubiaceae. 
olate to obovate pointed glossy leaves which are crowded at the ends of the 
branches. The flowers, which are of a white or pink color, are borne all along 
the slender branches and are quite fragrant. 
The dark yellowish green wood becomes very fragrant on drying and re- 
sembles the odor of true Sandalwood. After the supply of the latter became 
exhausted in the islands, it was shipped to China as a substitute. The Naio is 
peculiar to this archipelago, though undoubtedly it must have originated either 
from Australia or New Zealand, the home of most of the Myoporums. 
Dead trees or old trunks are called Aaka by the natives. 
RUBIACEAE. 
The family Rubiaceae with its 4500 or more species and about 350 genera is 
a decidediy tropical one. The distribution of its species over Africa, Asia and 
America is rather even. Polynesia possesses also a large number of species. In 
the Hawaiian Islands this family is represented by 13 genera of which 4, 
(Straussia, Bobea, Gouldia and Kadua) are endemic. Eight of the 13 genera 
have arborescent species while the remaining 5 have shrubby or also herbaceous 
Species only, and are therefore here omitted. A large contingent of the Hawaiian 
Flora is made up of this family which is the largest next to ( Lobelioideae ) 
Campanulaceae and Rutaceae. The family is easily distinguished by its op- 
posite leaves and interpetiolar stipules.
