“ Each delicate flower has about two days of life. During rainy weather the petals fold over the green stigmas and the yellow stamens to protect them from moisture. The blossom closes with the last rays of daylight and reopens as the sun dispels the darkness, so that only the careful observer and the early riser realize that it “draws the drapery of its couch about it and lies down to pleasant dreams.” It is true that some wild roses may be found open at night, but these are the ones whose seeds are fertilized and whose pollen is carried off, so that rain and dew are no longer to be feared. ”
