Maples comprise one of the largest, most diverse, and most important groups of broadleaved trees in the world. There are about 125 species of maples in the world, with most living in China and the Far East. Maples are noted for their oppositely arranged and palmately lobed leaves, and their propellor-like seeds, called samaras.
Thirteen maples are native to North America; 3 are native to Oregon:
: leaves commonly 6"-12" in diameter (sometimes larger); samaras grow at right angles to one another and have fuzzy heads.
: leaves have 5-9 lobes and are generally 2"-4" in diameter; samaras grow at 180 degrees to one another and do not have fuzzy heads.
: leaves have 3 main lobes and are 2"-5" in diameter; samaras grow at right angles to one another and do not have fuzzy heads.
