Colour Challenge: Yellow Leaves

Or Yellow Stays, as the case may be.

Some leaves turn red, most turn brown, but, fortunately, some turn yellow, or I wouldn't have a photo to show you for today's Colour Challenge:

^{Olympus Stylus 1s, 60mm, ISO100, f5.6, 1/160s}

BTW this small tree has peculiarly shaped leaves; do any of you know what it could be?

Thanks for watching!
