N.B. reporting of the edit history is currently fairly unclear and misleading. Most edits made to specimens appear as a pair of 'add' and 'delete' entries, which may not be together in the list. There are also often 'minor' edits, which are made automatically (rather than due to user activity), for example to merge synonym names.

There is quite an extensive literature on how the insects etc of plant galls cause changes in the plant growth regulators to induce abnormal growths - have a quick google in "Google scholar"
