 the flowers pointed. Savaii. 



Bambos (No. 1 ; bis Taheiti), but seemed taller, and the stems more weak and brittle ;

Rhapis acicularis, (No. 1, bis Taheiti). Savaii seemed in the same state of aboriginal 

 cultivation as Taheiti is described to have been at the time of Cook's first visit; " the 

 parts near the coast covered with cocoa-nut and bread-fruit trees, beneath which is 

 very generally a green sward," seeming at first to " afibrd pasturage;" but on closer 

 examination, the sward proved composed in great part of the pungent Rhapis acicu- 

 laris.
