“ For only one night in each year does the Cereus Greggii come forth into bloom, scenting the warm sweet air of the desert land for miles and miles with poignant fragrance. When the shadows begin to lengthen and the deepening glow of sunset approaches, the satiny blossoms begin to open (having already loosened and expanded) ; in an hour or so they are fully opened, and as one stands watching them curiously one can actually see them moving and lifting from minute to minute, the petals seeming to tremble, so forcibly is Nature causing them to expand. ”
