out by Johow, it is also distinguished by the presence of domatia on the leaves. 

 It also differs in the somewhat larger and more obovoid fruit as well as in the 

 shape of the male flower, as seen from my figures. 



C. pyrifolium. is related to C. laevigatum Cheesem. from Rarotonga and to 

 other species from the same region, and probably more nearly allied to these 

 than to its congener in Masatierra. 



Area of distribution: Endemic.
