Uganda the above written facts respecting variability express themselves, so 
these data of some other species of coffee are seen to be ambiguous. 
In contrast to the variability in the numbers of Uganda, is the 
considerable uniformity in the numbers of C. Kobdusta involved in this 
enquiry, which are at the same time more difficult of analysis and less 
convincing. As well as in the phenomenon above mentioned this appears 
in quite another region. 
I counted from the examples experimented on, both the number of 
leaves of a whole tree as well as the lengths of the internodes; again the 
measurements of each branch-pair were computed. So I added the mea- 
sured internodes-lengths of the two branches of one branch-pair, and 
determined also its total number of leaves; but, as towards the top of the 
tree the branches became shorter and the number of leaves decreased, I 
reckoned the number of leaves of the branch-pairs by putting the branch 
lengths at Iooc.m. Per 100 c. m. branch-lengths, the number of leaves 
of the whole tree, beginning from the foot of the tree, amounts to:
