This group of street trees are not on the city's list. They look like Fraxinus angustifolia subsp. oxycarpa, and judging by part of the tree being missing, may be the cultivar 'Raywood' that's known for losing branches. But the leaves are so compressed on the branches, I wondered whether it's some other cultivar that's supposed to have this compressed appearance (is there a 'Tiger Tail' cultivar??), or are these trees just sick? Or are they not even Ash trees?
The one on streets here that looks like antlers is this. http://jfschmidt.com/introductions/leprechaun/index.html
Oh, "antlers" - I had the wrong end of the (wrong) beast (in thinking "tiger tail"). I've always had trouble recognizing representations of animals. Thanks, Ron. Ron's link goes to J. Frank Schmidt's page on Fraxinus pennsylvanica 'Johnson', Leprechaunâ„¢ Ash, a genetic dwarf form of the green ash. Kwantlen has a photo that looks a lot like it.
