Found in shallow water and low moist grounds, from July to August.

The leaf- and flower-stems rise 1 or 2 feet from the root.

The leaf varies very much in size and proportion; it is arrow-shaped, with strong ribs, a smooth and fine surface, and is borne on a single stem that rises directly from the root. It is green, of a vigorous quality.

The flowers leave 3 rounding petals, concave, and of an exceptionally pure white color. They are of two kinds, sometimes borne on separate stems, sometimes upon the same stem (in which case the stamen-bearing flowers are placed upon its upper part); the stamens are many, and of a pure orange yellow, making a heart of gold in their white blossoms, while the pistil appears in its flower as a beautiful light green ball. The calyx is green and 3-parted. The flowers are arranged in whorls of threes and fours, upon inch long foot-stems, which are placed along a large many-angled, green stem, rising from the root.

The Arrowhead is attractive in all its parts, and in its gesture; it is truly decorative, and suggests the subjects treated by the best Gothic artists.
