DISTRIBUTION OF PLANTS. 



Peperomia (No. 6) ; pubescent ; simple-leaved. Muthuata, and elsewhere ; frequent 



(No. 7) J a second species. Smooth; entire-leaved. "Ovolau," Brackenridge. 



(No. 8) ; a third species. Smooth ; the leaves larger. " Ovolau," Brackenridge. 



(No. 9). Minute; leaves radical, petioled, round-elliptic. "Ovolau," Bracken-

 like those of Casuarina, but larger. Seen only in the tract of country back of the 

 Middle village on Mbua Bay. 



Dammara nov. sp., (No. 1) ; the leaves seeming broader than in the New Zealand sp. 

 A single young stock, twenty feet high and bearing male flowers, observed on the 

 mountain-summit behind Muthuata, at the elevation of two thousand feet. On other 

 mountains, the tree may probably attain large dimensions : the resin, which entirely 

 resembles the New Zealand kind, is used by the natives for glazing pottery; and 

 timber suitable "for spars" was spoken of by residents.

 near P. elongatus ?. Arborescent, becoming a small tree, twenty feet high ; leaves 

 alternate, lanceolate, two to three inches long, having a midrib but no lateral nervures; 

 no flowers. On mountain-summits on Ovolau, at the elevation of '2000 feet. 



(len. incert. with sessile fruit, (No. 1). A shrub, twelve feet high; leaves alternate, coria-

 nate; racemes, below the leaves, of obovoid drupes as large as cherries, each containing 

 a single large nut. In the Sandal-wood District. 



Gen. incert. with solitary berries, (No. 1). A shrub ; leaves alternate, lanceolate, entire ; 

 calyx five-fid ; berry solitary, pedicelled. Muthuata, at the elevation of fifteen hundred 

 feet.

leaves scattered, denticulate. Ovolau. 

 Halophila ovata ; bis (No. 1) Samoa (to Tongatabu). Marine; growing in sea-water on 



the coral-shelf, but not abundant.

 Growing in cultivated ground, and also in wild situations as high up as fifteen hundred 

 feet on the mountains. 



Lemna (No. 1). Abounding in taro ponds, at Rewa, Mbua Bay, and elsewhere; (having 

 been introduced by aboriginal settlers).
