The Blossom of the Walnut
The walnut, like many other trees, is a wind loving plant and depends upon the swish of its branches in the breezes and the breezes themselves to carry its pollen from limb to limb and tree to tree. The direct color photographic print shown here is that of the pistillate, or pollen receptive blossom of the walnut tree, upon whose slightly sticky surface the flying pollen finds lodgement, its grains fertilizing the seed, combining with it to produce a crop of walnuts.
