Galls exactly similar to those of the previous species. They 
have been already described as occurring in various parts in 
the tropics. Particulars are to be found in an article on these 
galls that appeared in the Bulletin du Jardin Botanique de 
Buitenzorg. Série ILI. Vol I. This gall was long since reported 
from Lang-Eiland. Borrtacs found it in 1896; I have seen the 
galls on the herbarium-materials collected by him. I myself 
found the galls in April 1919, chiefly in the higher parts and 
even on-the top of the mountain, but on my last excursion I 
found it also in other places.
