Flowering time. - Summer. Part employed. - The ripe fruit.
Characters. - Stem rooting at the base, and either thickened and erect, or elongated and creeping, or floating, according to the situation it grows in. The flowering branches erect or ascending. Stem-leaves twice or thrice pinnate, with small oblong and entire, or cuneate and lobed segments; or, when under water, all the lobes are narrow and long, sometimes capillary. Umbels on very short peduncles, either opposite to the leaves or in the forks of the branches. Rays seldom above 12. No general involucre, and but very small, narrow bracts to the partial ones. Fruit shortly pedicellate, cylindrical, with 5 scarcely prominent, broad ribs, and single vittas under the furrows. The calicine teeth are very minute. Care must be taken to distinguish these from the seeds of Sium latifolium, which are smaller and broader; the 5 ribs are much more slender, and there are several vittas under each interstice, while the small calicine teeth are usually very distinct.
