not send any flowers, and I suppose he had a flowering 
specimen of a Phyllagathis before him, when he wrote down 
these remarks. This error is the more probable as the 
specimen he sent very much resembles Phyllagathis in habit, 
and the capsules of that specimen are without exception 
pentamerous. Only in a few cases one valve is distinctly 
smaller, but not quite suppressed,

Before I try to draw any conclusions from the facts here 
stated it will be useful to summarise the main points. I think 
I cannot do it better than by means of a scheme, given at 
the end of this paper, which expresses in a concise way 
the arrangement which I think best represents the natural 
differentiation of the Asiatic Sonerileae. I do not pretend 
to give a table showing the descent of these genera and 
species. This would be far more than I can possibly prove. 
It is nothing more than a short transcription of the rather 
long exposition I have been compelled to give. If there 
result from it in the end any suggestions as to the phylo- 
genesis of the Sonerileae they will be the more valuable 
as they are derived solely from facts. 
In order to simplify the scheme I have divided it into two 
parts. One part shows the arrangement of the species of 
Sonerila, the other of the remainder of the Asiatic Sonerileae. 
The species are arranged within the groups so as to indicate 
roughly their greater or lesser affinity. Double lines mean 
that the species thus connected form probably one uninter- 
rupted series of forms : single lines, that the affinity is very 
close although there is a distinct gap between them : whilst 
the names of species which occupy a more isolated position 
are not linked at all. Thus the attention of botanists who 
intend to study the subject further, and particularly of those 
who are in a position to pursue it on the spot, will be drawn 
immediately to the more critical and questionable species. 
The lines connecting the groups show in a similar way the 
degree of affinity and the direction in which they approach
