Eveexta Jamposa, Linn.—Planted and naturalized in several localities. Called by 
the natives Kahika-papa, or the foreign Kahika. 
South of China to Australia. 
*Psrpium GUAJAVA, Linn,—Plentifully naturalized, but has not spread so extensively 
as in Tahiti, where it has displaced the indigenous vegetation over large areas. 
Now naturalized in most tropical countries, but originally from Mexico. 
BARRINGTONIA Buronica, Forst.—Native name Utu. Common all round the island, 
particularly near the sea. Probably the finest tree in Rarotonga, attaining a height of 
60 or 70 ft., with a wide-spreading crown of branches and massive trunk sometimes 6 ft. 
in diameter. As in other parts of Polynesia, the outer portion of the fruit is grated and 
used as a fish-poison. 
Pacific Islands, from New Caledonia to the Paumotu Islands, northern shores of 
Australia to Malaya and India. 
MELASTOMACE. 
MELASTOMA DENTICULATUM, Labill—Native name Kotaa. A common shrub in open 
places on the hills. 
Plentiful in most of the Pacific Islands, from New Caledonia to Tahiti. 
ONAGRARIACE. 
*JUSSLEA REPENS, Linn.—Plentiful by the margin of a stream at Ngatangiia, but not 
. seen elsewhere. Probably a recent importation. 
Most warm countries. 
*JUSSLEA SUFFRUTICOSA, Linn.— Abundant in Taro-swamps throughout the island, and 
presenting all the appearance of a true native. The chief Tarare informs me, however, 
that it was introduced from Tahiti about 25 years ago by a half-caste called ** Jim " 
Harrison, and that the natives gave it its present name “ Ziemu” from his name “ Jim." 
Widely distributed in warm countries.
