placenta has become filiform. At length the summit of the fertilised 
covule arrives at the top of the ovarian cavity, with which it appears 
to contract a slight adhesion, which is doubtless the reason why it has 
been taken to be pendulous. Moreover in C. angulata, a new species 
from New Caledonia, sometimes three or four ieclen are found in each 
vary. 
The classification proposed is essentially the modification of 
Migquel’s arrangement adopted by Mr. Bentham, with the addition of 
a second division to include for the most part several New Caledonian 
types. Fully drawn out the genus stands as below
