Nat. Ord. (Natural Order) Leguminosï¿½. Lin. Syst. (Linnean System) Diadelphia, Decandria. This is a well-known American tree, found growing wild in all of the states west of the Delaware River. It is a tree of secondary size, attaining generally the height of forty or fifty feet. The leaves are pinnated, bluish-green in color, and are thinly scattered over the branches. The white blossoms appear in June, and are highly fragrant and beautiful; and from them the Paris perfumers distil an extrait which greatly resembles orange-flower water, and is used for the same purposes.
