tioned above. Hither the leaf is conduplicated by uniting its edges, or a part of 
its surface near one side is folded over the rest of the leaf and kept in that position. 
A kind of pouch is formed, open on one or both ends. This grows bigger and even 
hypertrophies, and when exposed to the sun turns pinkish-red, like true galls. Being 
swollen outwards it is quite roomy inside and contains bead-like drops of honey-dew, 
whitened by the copious powdery meal. Frequently it is quite full of teeming Aphids. 
The illustration shows the galls of almost natural size on the branches; the one 
split open to show the interior is one and a half times natural size. |
