Plant anatomy; Botany; Botanique; Botanique. 56 OK MTUUCTUHAL IJOTANV. Ill boarin<,'; otliorwiflo t)u! wind is tlio i)rincipal nfiont. Flowors wliic'h dupond on insects to ofFoct tho transfer of pollen from the anther to the stigma are said to bo onto- mophilous. Those which depend upon tho wind are anemophilous. The Willow belongs to tho former class. 75. Maple. In oarly spring, while the branches are us yet bare of leaves, our Red Maples are covered with a profusion of scarlet and yellow blossoms, and the air about them is alive with busy insects gathering honey for themselves, and performing at the same time an 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 reddish twigs will present the appear- ance shown in Fig. 72,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 Fig. 73, except that the number of stamens will probably be found to be somewhat variable. Observe 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 kind. Fis,'. 72.—Twig of Red Maple bearing staniiiiatc flowers. Fig. 73.—Single staniinate flower.
