Tliis graceful and liandsoine Talm agrees well in its generic characters 

 with (\vph()keutia, though it is geographically far rcmovetl from the other 

 species of the genus which are all endemic to New Caledonia. It is stdl 

 quite common in the more sheltered places on all the larger islands of the 

 Bonin group and esi)eelally on Ani-jima. From a distance old trees resemble
