cultivatioiij we had before seen at O-Waihi; and twelve, 

 including the Cocoa Tree, were collected at the Island 

 RomanzofF, where we gathered in all but nineteen species. 

 About twenty, again, we found at Guaja. Neither the 

 Orange nor Cabbage Palm, both of which have, on doubtful 

 testimony, been stated to grow on the Mulgrave Islands, 

 could we find; nor learn any thing with certainty about them. 



We do not however believe that the vegetation of Radack 

 is confined to the above-mentioned number of plants; but 

 rather think that both on this island itself, and the groupe of 

 which it forms a part, and which we had not the opportunity 

 of thoroughly investigating, many individuals may have 

 escaped our search. The southern islands, iu particular, 

 which we did not visit, (Arno, Meduro, and Mille,) which 

 have an older vegetation and much richer soil, are likely to 

 produce many species which are wanting to the more northern 

 and barren groupe. Vegetation appears on this chain of 

 islands to have commenced in the south, and followed the 

 course of the inhabitants, in a northerly direction. 



The most useful Palm found here is the common Pandanus 



or Screw Pine of the South Seas, ( Wob.) It grows wild in 



the most arid sands, where vegetation first commences, and 



enriches the soil by its numerous decaying leaves, which it 



throws off in great numbers. In the moist lowlands of the 



richer islands, it thrives equally well, and numerous varieties 



of it are cultivated with care, being propagated by layers, 



and their fruit much improved by culture. All of these, if 



increased by seed, reassume the original characteristics of 



the parent species, the Eruan. More than twenty varieties 



are^ reckoned ; the difference between them existing in the 



various outward form of tlwjir fruit, or its compound nature, 



or the number of separate kernels which it contains. The 



male tree is always called Digar, the wild female, Eruan; 



each variety having a different name. That part of the fruit 



which is used for food by the people of Radack, is by the 



natives of the Sandwich, Marquesas, and Friendly Islands 



employed as an odoriferous and golden-shining garland. 



We may here remark that the genus Pandanus particularly
