The Willow belongs to the former class., 75. Maple. In early spring, while the branches are as yet bare, of loaves, our Eed Ma:plea are covered with a profusion of scarlet and yellow ^ossoms, and the" air about them is alive with busy insects gathering honey'for themselves, and performing at the same time ah impor- tant service for the trees in return ; for it will be found on examining a few of the trees that, like the Willow, they do not all bear the same kind of flowers. In some, the ends of the red dish twigs will presejit Reappear- ance shown in ,withnumerous stamens'protruding from the scaly lateral buds. On looking into one of these buds it will be found that there are several flowers on short pedicels, each like that shown in Kg. 73, except that the number of stamens will'probably be found to be somewhat variable. Pbserve the fleshy disk in the bottom of the calyx, upon which the stamens are inserted. These flowers with the projecting stamens are without pistils. They produce nothing but pollen, and the tree upon which you find them produces no other Fig. ITS.
