each other most. Where the mutual approximation is 
doubtful the line is stippled. 
The more important facts which we may grasp from this 
scheme may be stated thus : 
1. The species of Sonerila group round eleven types. The 
number at present known is 61, of which io, however, are in 
so close a relationship to other species that it is very probable 
that they will be reduced, with further material. 
2. The species belonging to one group are closely or very 
closely allied, or they assume a comparatively isolated position : 
but their affinity to at least one of the other species of the 
group is greater than towards any species of any other group. 
3. The species of one group cannot be arranged as a 
rule in a linear series, but they are linked variously to each 
other. 
4. One or several species of one group show a closer 
affinity to another group, whilst the remainder diverge more 
or less from this line of connection, thus forming the blind 
terminations of the ramification of the group. 
5. The groups are connected to each other in an analogous 
way. 
6. The groups of .S'. linearis, squarrosa , scapigera , and 
maculata converge towards a line which is occupied by the 
groups of 5 . zeylanica , tenuifolia , Gardneri , versicolor , and 
speciosa. 
7. The groups of 5 . obliqna and 5 . moluccana approach each 
other more than any other group, but they hold an isolated 
position within the genus. 
8. Within the groups of the zeylanica-speciosa line we 
find a species in which both whorls of stamens are developed, 
vS\ Bensonii ; and the same is the case in the two or three 
species of the obliqtia-g roup to which .S', moluccana and its 
allied are linked. 
9. In all other Sonerileae besides Sonerila , both staminal 
whorls are developed.
