The three-flowered maple is a 10 to 12 meter high, slightly branched tree with a striking yellowish-brown colored bark that bursts lengthways on the trunks and branches and curls up. The shoots are light to ash brown. The leaves are threefold. The leaflets are 4 to 9 inches long and 2 to 3.5 inches wide. They are obovate to lanceolate and with entire margins to roughly serrated. The upper side of the leaf is initially hairy, the underside is lighter and only the nerves are hairy. The petiole is 3 to 5 inches long and somewhat hairy. The leaves turn golden yellow to orange in autumn. The yellow, five-fold flowers are in clusters of three on short shoots. The species blooms from April to May. The fruits are greenish yellow, thick, densely hairy and 3 to 5 centimeters long. The wing is obtuse and spread at an acute angle. The fruits ripen in September.
