This power of the stigma is probably due to varying properties of the secretions which are found upon its surface. It has been found that on some stigmas pollen from the same flower will not germinate, while pollen from other flowers of the same kind will germinate. This is true of buckwheat and of the day-lily. This fact evidently prevents close-pollination in such plants. Much more common, however, are cases in which pollen does germinate upon its own stigma, but not so well as it does on other stigmas. Thus if pollen from the same flower and pollen.
