any ideas?

Well every one is going for Hedera Helix but I have looked through as many types as I can find and non have this leaf shape or form .

It's difficult to see from the pic, especially on my iPhone, but I think it is most likely to be Hedera nepalensis.

Ah . That's looking closer . Himalayan

Isn't this just arborial ivy? Ivy has two leaf types, bit like holly.

In the case of ivy the leaves are palmate at the bottom and lanceolate once they reach a certain height up the host where it flowers. I think it helps to reduce the effect of wind.

 

Holly has a similar leaf change where all the prickles are at the bottom of the tree, presumably because they haven't evolved with Giraffe.

Everyone going for Hedera, no-one mentioned helix. But for what it's worth the leaf form of helix is very variable, everything from lobed to fiamond shaped to boat shaped. helix has different lifestages, creeping and climbing, in various states of shade and sun and wind exposure, so perhaps leaf shapes are manifestations of individual positions? And that's before getting into ornamental varieties.

 

Here's a pic of mature form of helix borrowed from pinterest.

 

Personally I wouldn't look further than H helix, but I suppose another Hedera species is possible.

Well I have to admit I did not know that . Every day is a school day as they say .

I thought Holly was pricklier at the bottom to discourage grazing by animals. I never noticed it on ivy.

I've just looked at the pic on my computer rather than iphone. I still think the leaves look narrower than those of H. helix. Although knowing how ubiquitous H. helix is, I guess it is most likely to be that.

 

Just out of interest Roscoe, is this ivy tree/bush located within a garden or it is public open space/countryside?

Here are a couple of pics of some ivy I have growing up a stone pillar. The top has mainly gone into arborial mode, but these branches have both leaf types.

 

 

 

 

..couldn't find any with prickles, maybe the giraffes have had them...
