1824—Leaves five lobed, slightly toothed, glaucous underneath; peduncles very simple and aggregate: of this tree there are two varieties in nurseries. 1. The Virginian scarlet-flowering maple. 2. Sir Charles Wager's flowering maple. With us it is propagated for the sake of the scarlet flowers which appear in the spring. In Pennsylvania, where it grows in the swamps, the natives use it for almost all sorts of woodwork; with the bark they dye a dark blue, and make a good black ink. The Canadians tap the tree, and make sugar and treacle from the juice.
