Acer macrophyllum
bigleaf maple

Sapindaceae (soapberry family)
Alaska to California
Acer macrophyllum new leaves. John Rawlings, Mar 2005

The deeply cut leaves, about 6 inches across or more, have wiggly edges, a pale underside, and stalks 6 or so inches long. The samaras, which are red when young, have a furry body and the wings do not diverge much, in fact they may overlap.

There is a specimen standing near the Norway maple northwest of Frost Amphitheater off Lasuen Street, and several between El Camino Real and Pampas Lane and between the Credit Union and Stanford Auxiliary Library. Specimens also can be seen in Atherton at Oak Grove and Middlefield Road. Bigleaf maple is a native tree of Jasper Ridge Biological Preserve and the foothills and creeks close to Stanford.
