Unknown low-desert broadleaf tree-- round 2 - Phoenix

[fastfeat]

This was sent by an arborist friend in Phoenix. And I'm pretty certain it's the same species of tree that I posted from Cathedral City a couple of years ago. (The Cat City tree was topped hard and had lusher, glossier leaves, clearly...) No thorns/spines, no known fruit, probably deciduous, probably non-native. Somewhere in between Celtis, Morus, Zizyphus in appearance, but I haven't been able to find a fit in any of those. If anyone else has seen this tree in your (low desert) neighborhood, please LMK... Thanks.

First three from Phoenix; second three from Cathedral City.

Seems reminiscent of the Japanese raisin tree (Hovenia dulcis) tree to me, but not certain. I wouldn't expect that species to do too well in low desert either, so it is probably something else.

Is somewhat similar, but, as you stated, not really a desert tree. Will take a closer look at that tho. Thanks.

Its a nice looking tree whatever its is.

In the last picture - what are the large leaves underneath it? The "Alligator Plant" ? The botanical name escapes me at the moment.

I believe it's zucchini or some cucurbit. Mostly fruit and vegetables in the yard of the Cathedral City tree. It's why I first suspected it might be a fruit tree.
