Any thoughts on what has caused this rather odd pattern of growth on bramble. Perhaps mechanical damage?

Intend to look it up in the galls guide next time I am at my local nature reserve - might be in that.

Nothing in galls

Couldn't find anything in the galls book. So perhaps it is viral.

Leading theory (based on comments on the UKWildlife group - http://groups.yahoo.com/group/ukwildlife/) is that this is caused by the use of Glyphosate near by to control Japanese Knotweed.

I would concur

I've seen similar results on brambles sprayed with glyphosate.
