The Wild Celery Of Christmas Lake, Hibbert Hill
Journal of the Minnesota Academy of Science
The growth and reproduction of Vallisneria as seen and photographed below water in Christmas Lake, Hennepin County, Minnesota, is described. The functions of the water surface film, of wave energy, and of the coiled stem of the pistillate flower, in fertilization is discussed. It is found that many of the plants grow in such depths that fertilization is impossible.
