Any ideas

Red buckeye-aesculus pavia

 

Still convinced it's a S. sargentiana. The description matches what I see in Flora of China - Sorbus sargentiana in Flora of China @ efloras.org.

 

The leaflets are starting to turn the classic yellow/red autumn colour of s. sargentiana, starting from the edge and that reddish sticky bud is a give away.

 

Leaf veins match, and it has large leaves for a Sorbus. Stout twigs/branchina and a small to medium size tree. This particular individual obviously didn't fruit well this year, because if there was fruit cluster that would be a key diagnostic feature also:

Yeah its the lack of fruiting clusters thats got me doubting your ID,im no expert just flicking through some books and putting up some species that match the photographic profile.

This tree looks to be Sorgus sargentiana, large pinnate leaves and what look like sticky reddish terminal buds.

 

 

 

Lovely species, one of the nicest in the genus.

 

 

Are you sure. I'm still confused about this one. It does look similar but still not 100% on it.

Can anyone give me a reason as to why it is not a Tetradium daniellii? It the closest thing I could find but its not a species I have come across before.

Thanks for the help

Tetradium danielli has smooth beech tree like bark,where as this specimen looks as though the bark is rough or a fissured texture.Also the leaves barley change colour in the autumn only going to a slight yellow,where as this tree seems to be going through a really noticable change in colour.If it had berries on it i would be more inclined to agree with you to its ID.

Which further strenghthens the case for s. sargentiana. I know it's shocking to see a rowan species that has nice bold foliage. I think its the lack of close up of buds and no fruit corymbs which would give it away. The general 'stout' appearance of the twigs and tree absolutely give it away as sorbus sargentiana.

 

What context is this tree in? arboretum? park?

There's a S. sargentiana at Harcourt Arboretum I saw in teh summer. Here's pics. It was grafted onto what I think was plain S. aucuparia. Hence the last two pics showing suckering foliage typical of S. a.

Yep, foliage seems to match, although the buds on this one appear green I'm still positive the original picture is of s. sargentiana, there are a few related species eg. s wilsoniana and s. insignis, but it doesnt fit. This species is typically grafted onto s. aucuparia rootstock.

Second image in Dalton trees also shows, the basal leaflets, which is characteristic in s. sargentiana and other related Rowans. If original poster can take shot of these then it could be more diagnostic.

Agreed...

and nice detective work my friend!
