Acer macrophyllum Pursh, Fl. Amer. Sept. 1: 267 1813. (Syn: Acer auritum Greene; Acer dactylophyllum Greene; Acer flabellatum Greene [Illegitimate]; Acer hemionitis Greene; Acer leptodactylon Greene; Acer macrophyllum f. angustialatum Schwer. …………; Acer murrayanum Dippel; Acer palmatum Raf. [Illegitimate]; Acer platypterum Greene; Acer politum Greene; Acer stellatum Greene);
It is native to western North America, mostly near the Pacific coast, from southernmost Alaska to southern California. Some stands are also found inland in the foothills of the Sierra Nevada mountains of central California, and a tiny population occurs in central Idaho.
It has the largest leaves of any maple, typically 15–30 centimetres (5.9–11.8 in) across, with five deeply incised palmate lobes, with the largest running to 61 centimetres (24 in).
The flowers are produced in spring in pendulous racemes 10–15 centimetres (3.9–5.9 in) long, greenish-yellow with inconspicuous petals. The fruit is a paired winged samara, each seed 1–1.5 centimetres (0.39–0.59 in) in diameter with a 4–5-centimetre (1.6–2.0 in) wing.
