C. turgida is distinguished from all the other species as Prain 
pointed out, by its separable endocarp. This integument pre 
invests the seeds and possibly aids in their dispersal in a living 
state by sea-currents. Its range is a large one reaching from 
Hawaii to the Mascarene Islands and including India, the Malay 
Islands and New Guinea, in all of which it is found climbing 
on the bushes that fringe the sea-shore. 
The two remaining species C. galeata and C. sericea inhabit 
Polynesia, the first to the north and the second to the south 
of the equator. Their peculiar floral characteristics unite them 
into a group by themselves.
