THE VOYAGE OF H.M.S. CHALLENGER 



probably, is there so large a number of peculiar types in so small an area ; there being no 

 fewer than six monotypic genera of palms restricted to these small islands. 



Most of the plants collected by Hume in Diego Garcia are also in the collections from 

 the South-eastern Moluccas, and those which are not are all widely spread species. The 

 only other plant we have seen from the island is an endemic fern, Asplenium cpquabile, 

 Baker, a distinct species sent to Kew some years ago by Lady Barkly. 



In the body of the present work full details are given of the distribution of many 

 plants which extend to Polynesia, especially such as reach the more remote islands. For 

 purposes of comparison, and as a specimen of the botany of some of the smaller Pacific 

 islands lying thousands of miles apart, the following lists of plants recently collected are 

 interesting. Associated with a number of common littoral plants are a few peculiar to the 

 region. Such are, Lepidium piscidium, Heliotropium a/nomahim, and Timonius forsteri.
