Flowering tree ID needed

[Tracy]

My wife and I were out for a walk this morning and have seen several of these trees in bloom around the neighborhood.  I'm hoping someone can provide an id with the leaf structure and flower pictured.  Thank you.

X Chitalpa tashkentensis.. a cross between Catalpa bignonioides, and Chilopsis linearis, aka Desert Willow.

An intergeneric cross that, at least here in California, is very prone to leaf fungus and subsequent leaf drop. https://selectree.calpoly.edu/tree-detail/×-chitalpa-tashkentensis Be forewarned.  I grew one at my last place and removed it for that reason.

Interesting.  One would think that leaf fungus would be a real problem here because of the persistent spring and early summer marine layer, but this is an older tree that wasn't showing any signs of leaf fungus or mold.  It was quite healthy looking along with the others we have seen growing here in Leucadia.  I don't plan on adding any trees, but my neighbor is redoing their front landscape and is looking for a pair of smaller trees and I'm offering some suggestions for trees they might consider.

I wonder if the Fungus/ scorch issue is more of a problem in drier parts of CA / here in AZ  as i see similar problems on specimens here..

As far as small-ish / smaller Trees,  If still available / can be ordered from them,  Monrovia was supposedly offering Cassia splendissima " Golden Wonder " again not too long ago.. Typically won't get too big / can be trimmed if it tries ( to get bigger ) Foliage resembles Cassia fistula, but Golden Wonder is more cold tolerant overall..  Flowers,  produced from late October- about Christmas time there/ up in San Jose, are quite large and will stop everyone passing by..  Neighbors still ask what happened to the specimen i'd planted in front of my Grandparents house 12 years ago..

Imagine Dias cotinifolia would be another nice exotic small tree to research, though your neighbor would have to start w/ small specimens. Don't think anyone is growing larger ones out there yet..

To my eyes only the newest leaves on the tree in that picture look healthy. The older leaves all have spots and discoloration. The tree has 'hybrid vigor' and struggles to keep ahead of the fungus: foliar powdery mildew. https://www.researchgate.net/publication/228656338_Susceptibility_of_Catalpa_Chilopsis_and_hybrids_to_powdery_mildew_and_catalpa_sphinx_larvae

I had a follow up question about another tree, which I posted in the wrong string.  Darold answered the question for me though.  Arbutus marina.  Thank you Darold!

** Quick correction**, Not sure why i did this, < again > ( i know better, lol ) but the above mentioned Cassia/Senna species is Senna splendida,   ..not splendissima..   Not sure why i always mess up the species name on it,   Grr..   My apologies for any confusion

Not a problem... I don't know if I messed up the keying when I ordered labels a few year's back or if the label maker made a mistake, but I have Cycas thouarsii x Cycas cupida which came out right on the tag. When we switched genus to my Encephalartos cupidus it came out as "cupida" .  I haven't replaced it so it is there to remind me of the error every time I walk by.  Easy mistakes to make!

It is sometimes.. 

Whats a bit more amusing is Monrovia may have botched the name of this particular plant from the start.. As referenced last year in the " A case of mistaken ID?" thread, this species may be Senna macranthera and accidentally miss-labeled/ marketed S. splendida.  Looks like macranthera when researched, and can't find much info regarding in situ documentation/ research involving S. splendida.   Great small tree regardless..
