Usually only one of these little blossoms in a cluster on each plant opens at a time; but that one peers upward so brightly from among the grass it cannot well be overlooked. Sitting in a meadow sprinkled over with these yellow stars, we see coming to them many small bees--chiefly Halictus--to gather pollen for their unhatched babies' bread. Of course they do not carry all the pollen to their tunnelled nurseries; some must often be rubbed off on the sticky pistil tip in the centre of other stars. The stamens radiate, that self-fertilization need not take place except as a last extremity. Visitors failing, the little flower closes, bringing its pollen-laden anthers in contact with its own stigma.
