| | | Tree (prob native) ID please
Hi! I'm interested in this tree, in a hedgerow planted I think by HCC, and in which case it would be native. Its pussy willows are just opening, ahead of any leaves, and you'll see the trunk splits into several, but perhaps it's been pollarded. The leaves under it are ovate, faintly waxy/leathery on top, paler underneath. And as you can see it has fruits of some kind. I'm especially interested as last year I seem to remember it was abuzz with bees later on, and I'd like to get one for the garden. Thanks for any help!    |

I should think its a willow; I would think the 'fruits' are actually galls but they're not one that I recognise.
Worth looking at http://www.british-galls.org.uk/ ?

Thanks Paul. Yes, looking in my book I wondered about Dark-leaved Willow? And I, too, wondered if the fruits could be growths/ galls - but there seemed almost too many, and so evenly spaced? But I'll enjoy trying the galls route! Thanks again - Rhona |

I'd agree with Paul, it looks like a bud gall to me although I've never seen anything like it. |

Does anyone think this could be Crown Gall disease? Agrobacterium?

Thanks for the input. I'm wondering if I shld carefully remove one of the galls/ growths and bring it home for dissection. Would there be anything against doing that? |

Could these be female flower clumps rather than galls, they don't seem to have the randomness of galls.
A handy book (if I could find mine) is;
The Tree Identification Book
George W.G Symonds
Stephen V. Chelminski
This book shows fruits, leaves, bark, and compares similar trees as I remember it was not expensive but very useful (if I could find it)

You'll see that on the outside it just looked like lots of seedcasings or similar, fixed onto a corky centre. I prised a few off with a craft knife. When I cut into the corky centre it was hollow, and not smoothly hollow but divided into tiny open chambers - which I guess suggests the gall of an insect? Nothing flew or crawled out (mercifully)!
Any thoughts please?   |

Any thoughts please? | Gall certainly, perhaps affecting the flower (catkins) buds. Not surprising the chambers were empty, 'hatching' probably occured before winter set in. I suggest you re  ost on the Invertabrate sub forum Insects and Invertebrates - Eggs, Larvae and Caterpillars at wildaboutbritain.co.uk
and if no one there comes up with an ID, then maybe contact the Natural History Museum as you may have something unusual.
