Aceraceae – Maple Family

Plants in the mainly temperate Maple Family (Aceraceae) are trees and shrubs with opposite, palmately lobed, unlobed, or rarely pinnately lobed, generally deciduous leaves, small, usually yellow-green flowers with 0, 4, 5, or 6 petals, 4 to 6 sepals, and a superior, 2-chambered ovary, and nutlike fruits that are usually paired, winged achenes known as samaras. The samaras will spin like a helicopter blade as they fall, which helps them fly some distance away from the parent plant.

Listed below are some of the southeastern Arizona plants in this family.
