Acer rubrum (Red maple): Fruit
The small, red flowers have 5 short petals and are produced on slender stalks in clusters on young branchlets. The pendulant, 2-winged fruits ripen a month after flowering, while the leaves are still small. The wings are 0.5 to 1 inch long, slightly divergent and have swollen seed cases. The reddish-brown wings dry to brown and are shed individually in early summer.
