Negundo aceroides Moench. Sapindaceae. Ash-Leaved Maple. Box Elder.
A tree of northern North America. This tree, says Hough, is tapped for sugar in Canada and is now being planted in Illinois for sugar-making. Vasey says experiments in Illinois show the box elder to give more sap and a more saccharine sap than the sugar maple and that this sap makes a whiter sugar. Douglas says the Crow Indians make sugar from its sap, and Richardson says this is the tree which yields most of the sugar in Rupert's Land.
