|Family Aceraceae - Maples|
Maples are some of our most familiar and beloved trees. The sugar maple has perhaps the most
spectacular display of autumn colors of any tree species in North America.

Maples grow to 45 meters (145 ft), or occur as shrubs less than 10 meters tall. Most are deciduous, but a few in southern Asia and the Mediterranean region are evergreen. Most are shade-tolerant when young, and are often late-successional in ecology; many of the root systems are typically dense and fibrous. A few species produce root sprouts which can develop into clone colonies.
Maples are distinguished by opposite leaf arrangement. The leaves in most species are palmate veined and lobed, with 3 to 9 (rarely to 13) veins each leading to a lobe, one of which is central or apical. A small number of species differ in having palmate compound, pinnate compound, pinnate veined or unlobed leaves. 
Maples are important ornamentals for lawns, along streets, and in parks. They offer a great variety of form, size, and foliage; many display striking autumn color. The red maple (A. rubrum) is one of the most common trees in its native eastern North America, where it tolerates compacted wet soils and city pollution.
Box elder (A. negundo) grows quickly to 30–50 ft (9–15 m) and resists drought, so early prairie settlers planted many for shade and for wood to make crates, furniture, paper pulp, and charcoal. The watery, sweet sap of the sugar maple (A. saccharum) is boiled down for maple syrup and sugar; the wood of certain maples is used for furniture.
