CHAPTER XVI 



THE RELATION BETWEEN LITTORAL AND INLAND PLANTS (continued} 



The Fijian difficulty. Inland species of a genus possessing fruits not known 

 to have any means of dispersal through agencies now at work in the 

 Pacific. Pandanus. Its remarkable distribution in oceanic groups. To 

 be attributed perhaps to extinct Columba2 or extinct Struthious birds. 

 Barringtonia. Guettarda. Eugenia. Drymispermum. Acacia laurifolia. 

 Conclusions to be drawn from the discussion. Summary of Chapters 

 XIV., XV., XVI Pages 155 169

 bijuga, inland and at the coast. The nature of the buoyancy of its seeds. 

 Summary relating to Afzelia bijuga. Entada scandens. Its station and 

 distribution. Darwin's opinion of the plant. The dispersal of its seeds by

Leguminosae predominate in tropical littoral floras. The anomalies of their 

 distribution in the Pacific islands. They conform to no one rule of dis-

PRELIMINARY COMPARISON OF THE PHYSICAL CONDITIONS OF HAWAII, 



FIJI, AND TAHITI 



Introductory remarks. The tranquil working of the winds and currents con- 

 trasted with the revolutionary influence of the bird. The Hawaiian, Fijian, 

 and Tahitian groups. Their surface-areas and elevations. Their climates.
