COSMOLEDO. 



Baty specially mentions P em phis, Tournefortia, Carapa, Rhi- 

 zophora and Casuarina as inhabiting this atoll. Dupont also 

 enters into some details of the mangrove vegetation, com- 

 prising the genera just mentioned with the addition of 

 Bruguiera, Ceriops, and Avicennia. But he gives no general 

 account of the vegetation. Fryer adds little, but he states that 

 the type of vegetation characteristic in Aldabra is quite absent. 

 Goelette Island, on the east side of the atoll, he found, was 

 u thickly studded with Plumbago aphylla, a herb which pro- 

 duces leaves at the beginning' of the wet season but speedily 

 loses them/' 



Dupont tabulates 43 species of plants from Cosmoledo, 

 including Apoch;fes, Plumbago, Solatium aldabrense, Sarco- 

 stcmma, Ficus natutarum, F. aldabrensis, Cassytha, Euphorbia 

 Abbottii, Casuarina, Lmnatophyllum , Dracaena reflex cmd 

 Asvaraaus umbellulatus.
