Subject: Aesculus with elephantiasis
Anyone seen this effect before - seen on two mature Aesculus hippo (not
x
carnea) in Devon. Occurs on terminal ends of branches on twigs 10-40mm
diameter before being inflated by the condition. Occurs mostly in upper
crown, but also on low laterals. There is a small lesion with
black/brown ooze on the distal end of the swelling. The last 3 years of
wood is normal white as per Aesculus; internal to that it is a rich
chestnut-brown. The swelling appears to have happened to the twig's
growth in early years, and is being gently accentuated by each annual
ring. Photo shows shoot sectioned; second email has 2nd photo of whole
shoot
Any suggestions'd be welcomed. The trees appear reasonably healthy in
other respects.
Rupert
