The resemblance is so great that there can hardly be a doubt of the 
generic identity of the Fijian and Philippine collections, although this 
involves the assumption that the ovary of the former has been wrongly, 
described. 
In the Philippine collections, the style is apical, entire at its base, 
but soon divides into 3 branches. This is usually evident both in flower 
and fruit, but sometimes in the latter the ridge overlying the ovule is 
sufficiently elevated to obscure the short basal portion of the style, and 
the lobes may seem to be separate styles. The ovary at anthesis already 
shows traces of invagination in its walls. In fruit, a cross-section shows 
sometimes a single cell with the lateral, apical, or basal walls more or 
less invaginated, or other fruits from the same plant may show these 
invaginations more or less constricted, sometimes reaching the center, 
sometimes not, so that at some levels they appear to divide the ovary 
into cells, as many as 14 having been counted. Sometimes these false 
cells are not developed at the apex leaving a considerable cavity in which 
the ovule is found. When there are several false cells, the outer surface 
of the fruit, always forming ridges, has one of these narrower than the 
others. This narrower ridge corresponds to a similar cavity, in which 
the ovule can always be found. In some cases this ovule extends to 
other false cells, but the ovary is always 1-ovuled. I have called these 
ovules rather than seeds, as they have never been found in our material 
in developed condition. This may not unlikely be due to the copious 
resinous secretion, described by the collectors as brown or black, or by 
one as milk and rapidly becoming a deep-black and strongly staining. 
Ho indication has been found that the above-described nature of the 
ovary is due to insect attack. There are two Philippine species referable 
to the genus, easily distinguished from one another by the very different 
size of the leaves, by their shape, pubescence, and somewhat by their 
venation.
