In late spring the little flowers of the milkwort are common upon dry hill-slopes in the shade of the trees. The small plants have a very grown-up look, as though their age might be greater than indicated by their stature. At first glance, one is quite certain to mistake these plants for members of the pea family, as the blossoms have wings and a keel like the papilionaceous flower. But a careful counting of sepals, petals, and stamens will reveal their separate identity.
A curious feature of this plant is the fact that it bears another kind of flower near the root. This is without petals, and is destined, for some strange reason, to bear the seed. The upper flowers seem mostly for show, though one does occasionally mature fruit.
P. cornuta, Kell., found in the Sierras, is a larger plant, with greenish-white flowers.
