The list contains 68 species, of which 18 are endemic, 13 are 

 limited to Aldabra and the small neighbouring islands of 

 Assumption, Cosmoledo, Astove, St. Pierre and Gloriosa, whilst 

 18 extend to Madagascar, and 11 reach East Africa. Prominent 

 among the genera found in Aldabra, but apparently absent from 

 the small islands nearest to it are: Grewia, Erytliroxylon, 

 Gouania, Tephrosia, Pithecolobium, Cassia, Lumnitzera, Son- 

 neratia, Tarenna> Tricalysia, Plectronia, Gvettarda, Psychotria, 



Triainolepis, Rutidea, Vernonia, Salicomia, Yiscum, Loranthus 

 and Angraecnat . Seven of these belong to the Rubiaceae, an 

 order scarcely represented in the smaller islands. Of course 

 it must always be remembered that Aldabra has been much more 

 thoroughly explored than the rest of the islands. 





Introduced Plants. 



In addition to the plants included in the enumeration as 

 probably indigenous, that is having reached Aldbbra inde- 

 pendently of active human agency, there is a number of un- 

 doubtedly introduced plants now existing in a more or less 

 wild condition. Such are: Amaranthui trislis, A. gangeticus, 

 Brassica nigra, Carica Papaya, Gossypium barbadense, Ocirnum 

 can-am, Rlcinus communis and, Lochncra rosea. Doubtless some 

 of those included in the enumeration might with eqiutl justic* 

 be referred to the category of introduced plants. 



The Coco-Nut. — I have not included Cocas nucifera in the 



enumeration of plants which have presumably reached Aldabra 

 independently of the action of man, because I am now con- 

 vinced that it is a native of South America, the home of all 

 the numerous species of the genus Cocos, and that its present
