Type ancient white oak into google and click images. Does that look about right? I really can't make out individual leaves in the painting but it makes me think old oak.

>As the species itself is naturally "pendulous" I doubt that it is any sort of cultivarThe plant shown here could have either been put on the market as a named form or as the typical plant. Similar plants being called cultivars are not hard to find in internet photos and elsewhere. >the weeping cultivars named above are much smaller than the speciesSpecimens being identified as 'Pendula' include one in Tacoma determined to be 74' tall during 1990 and listed by R. Van Pelt in Champion Trees of Washington State (1996, University of Washington, Seattle). A local known planting of 'Van den Akker', as identified for me by a member of the family who still propagates and sells the clone includes trees over 70' tall. It was grown originally by the father's nursery as 'Pendula'; the new name 'Van den Akker' is believed to have been first applied by T. Buchholz. Plants seen here labeled 'Green Arrow' show no obvious indication of being any more dwarf than these others. Common in Seattle, it is grown for its unique ornamental silhouette: most here are especially slender, gaunt, and strongly weeping, presenting such a wilted "Dr. Seuss" aspect that mistaking them for any other kind of tree (except weeping Lawson Cypress) is impossible. Such trees have been sold as 'Pendula', 'Strict Weeping', 'Green Arrow', 'Van den Akker' and the like --A. Jacobson, Trees of Seattle - Second Edition (2008)

That is a Japanese Fern tree ( Filicium decipiens). I think that is a very pretty tree. It will grow to about 30 feet tall.

I could see why you think it could be a Tropical Almond (teminalia catappa), but they are different. These trees have branches that go horizontal and the leaves are much larger, In fact i'm looking at the one I have in my yard right now and when I go to south florida tropical almonds are everywhere. I think Terminalia muelleri is probably right. Thanks anyway
