Leaf Identification
The leaves of the Three-Flowered Maple are compound, oppositely arranged on the stem, and unlobed. The leaves are medium-dark green and trifoliate (each leaf has three leaflets), turning a bright golden yellow/orange in the fall. Each leaflet is about 1-3″ and is elliptical in shape. The leaves have long trichomes along the end of the petiole and the base of the leaflet midveins. The leaflets may be pubescent (hairy) when young.
Twig and Bud Identification
The twig is orange-brown with pale vertical streaks and lenticels (pores). Leaves are arranged oppositely, and the twig is not zig zag. The terminal buds are small, dark, scaled, and in sets of three. The middle bud is the largest.
Bark Identification
The bark is smooth and tan when young, but as it matures it will begin to peel horizontally along the entire length of its bark. This peeling is often incomplete but happens over multiple layers, creating a clawed, shredded appearance.
Fruit Identification
The Three-Flowered Maple is a pubescent double samara (seed covered by papery, winged seed coat), with the two samaras angled 45 degrees apart from each other. The samaras mature in fall, where they turn brown.
Flower Identification
The flowers are inconspicuous, light green, and hanging from short peduncles. They are in clusters of three, as the common name of the tree suggests. They bloom in mid-spring.
