Family, Saxifrage. Sepals, 5, somewhat united. Petals, 5, white, large, veined with green or yellow. Five good stamens. At the base of each petal is a cluster of bodies which will puzzle many students. They are sterile filaments of defective stamens, 3 in each cluster. There are 4 stigmas, without styles, over the 4-valved capsule. Leaves, 1 on the flower-stem, near the base, clasping; others from the root, roundish, somewhat heart-shaped, with thick petioles. July to September.

Very pretty, conspicuous flowers, which it is a pleasure to find. Scapes 1 to 2 feet high. Flower 1 to 2 inches broad. New England to Florida and westward. In swamps or wet grounds.
