Tree ID - bipinnately compound

[Jdiaz31089]

I drive by these trees often, but haven't seen them in bloom at all. I was wondering if anyone could ID them. They are growing in z9b in Fresno, California. The leaves are bipinnately compound - twice divided - and If I remember correctly, the trees are briefly deciduous or partially deciduous. I may be wrong in that though. 

At first I though they might be jacarandas, but upon closer inspection they are most definitely not. My other thought is that they could be some sort of acacia. Thoughts? 

PLOT TWIST - They are a super duper hardy form of delonix regia 

I took these pictures as I drove by. If more detailed pictures would help, I can make my way there to take them. Thanks!

Peltophorum?

Can you get a close-up of twigs? I'm looking for thorns/prickles. Pods or portions of would definitely help too.

It is probably an Acacia species; not sure which yet.

If it has papery bark it could be Acacia sieberiana, now Vachellia sieberiana.

Good call. Thanks.

Here are some closer shots. I couldn't get closer shots of the foliage because the branches were so far up. I didn't notice seed pods or dried flowers of any sort.

Anadenanthera colubrina?

Looks thornless, so guess that eliminates both Anadenanthera and Vachellia... Perhaps a Leucaena species...

I've seen this tree before, but didn't get it IDed then. Let me shop it around...

Bit of a hard call between Delonix and Peltophorum, but I'd go for Peltophorum.

Trunk of Poinciana, Delonix regia

Trunk of Yellow Flame Tree, Peltophorum pterocarpum

Both are deciduous so hardly any leaves now but managed to find these on a Peltophorum.

Maybe Leucaena pulverulenta?

 

 

[Jdiaz31089]

I will keep my eye out for any blooms and report back. Peltophorum seems like a good candidate!

Looks like the tree at Alice Keck Park in Santa Barbara inventoried by me, perhaps erroneously, as L.esculenta. (H/T to Randy Baldwin of San Marcos Growers). I'm not certain if that ID was provided from Santa Barbara texts or not. Has been many years; can't recall...

This is not a genus I know well. How does L. esculenta differ from L. pulverulenta?

Here are some habitat pics of Leucaena pulverulenta from the Sabal Palm Sanctuary near Brownsville, Texas. 

Vs. Ebenopsis ebano

Also curious on id of this... first thought was some sort of Acacia or Leucana. Have both older Peltophorum dubium and africanum seedlings , and have worked with pterocarupm when in Florida. Individual leaflets of all three species are wider, more round.  Same general leaf arrangement with the Leucana sp. I've seen, or have here at the house ( L. retusa and the evil " White lead tree" that continues trying to germinate in the yard from neighborhood trees. Leaflets in the picture appear narrow, and appear to end in a sharper point. Like the white, smooth looking trunk. Reminds me of Lysiloma candida from Baja. 

Maybe contact Matt Johnson who heads the Desert Legume Program in Tucson. He might have additional insight into identification.

I'll swing by and climb if I have to in order to get a detailed photo of the leaves.

I think L. esculenta is a better match than L. pulverulenta.
