Report an issue with this species
Acer nigrum, also known as black maple, is closely related to the sugar maple but typically has three-lobed leaves with a drooping appearance, rather than five. It can be distinguished by its darker, more deeply grooved bark and slightly smaller seeds. Hybrids with sugar maple are common and exhibit intermediate characteristics.
