Please help me ID this tree. Stems are curious, look like they have been eaten away by some mysterious creature although this appears to be normal growth habit.
SOLVED: need ID for tree growing in Los Angeles
Looks like Corylus, the hazelnut

Which species? The stems on this tree are rough. Coryllus stems look smooth. Am I missing something?
Yes, growin, thank you! My photo matches up perfectly with pictures on your link. It is definitely Ulmus alata.
Sorry, I thought this was solved but my foliage really does look like Corylus (hazelnut) even though stems look like those on Ulmus alata! My foliage is much wider and less regular than that found on Ulmus alata.
Ulmus alata has much smaller leaves, barely 3 cm broad.
The leaves match fairly well with Corylus colurna, although it could well be another species
Thanks for trying but your twigs are smooth, mine are winged.
Yes the winged stems may be crucial and distinctive, although leaves don't seem to be matching.
Yes Growin, you finally got it, both nature of wings and leaves were troubling me. Ulmus alata has two opposite wings, here they are irregular corky in U. thomasii, larger and broader leaves, clearly unequal at base.
Ok, growin, I think you got it and thank you. We have an anomaly here. Look at geographical distribution and you will notice that Ulmus thomasii is found 2000 miles east of California! Also, literature says that this tree is not found in commerce, i.e. nursery trade, which means that it is probably from a seed that somehow hitched a ride West!
