OF BAOTJL ISLAND. 127 



tion of the tropical, widely diffused Pacific species, there are no 

 phsenogamic plants or ferns confined to Norfolk Island and Eaoul 

 Island. It is further remarkable that of the Eaoul Island ferns, 

 Gyathea medullaris and Pteris falcata have not been found in 

 Norfolk Island. 



There is no doubt that a complete flora of Eaoul Island 

 would modify these results ; but there can also be no doubt that 

 it would confirm these indications of its affinities being most 

 strong with that of New Zealand, and feeble to a very unaccount- 

 able degree with the floras of those other groups with which it 

 might be expected to possess a very strong relationship. 



Of the twenty flowering plants, three are noticed by the col- 

 lector as being possibly introduced by man, viz. Sicyos angulatus, 

 . Gnaphalium luteo-album, and Oplismenus cemulus, all of which were 

 found to affect cultivated ground. These are, however, so widely 

 distributed in the South Pacific Islands, New Zealand, and Au- 

 stralia, that it is quite as probable as not that they are truly wild 

 in the Kermadec group, and only grow in more abundance upon 

 prepared soil. All have, however, appendages that would favour 

 their transport, as the glochidiate seta3 of the fruit of the /Sicyos, 

 the awn of the glume of Oplismenus, and the pappus of Gna- 



With regard to the remaining seventeen flowering plants, I 

 recognize special adaptations for transport in the following two 

 only: — Bidens leucantTia*, in the barbed seta? of the fruit, and 

 Lagenophora petiolata, in the viscid fruit. Of the rest none seem 

 in any way adapted for transport, unless the minute and numerous 

 seeds of the Lobelia, Acianthus, and Metrosideros be so regarded.
