Acer henryi - Kruckeberg Botanic Garden at Richmond Beach in Shoreline, WA. This is considered to be one of two species in Section Negundo Series Cissifolia: A. henryi from China - Hubei and Sichuan, and A. cissifolium from Japan - Hokkaido to central Kyushu.
Though this thread has been inactive for some time, for interest I have added a picture of my A henryi covered in seed as it is each year. Alas all parthenocarpic as it is an isolated female tree.
