    • n sium A genus of umbelliferous plants, of the tribe Ammineæ and subtribe Euammineæ. It is characterized by flowers with numerous undivided involucral bracts, acute calyx-teeth, and slightly notched in flexed petals; and by fruit with nearly equal obtuse corky or thickened and somewhat prominent ridges, an undivided or obsolete carpophore, and numerous oil-tubes or at least one to three to each interval. There are 6 species, including the genus Berula (Koch, 1837), separated from Sium by some on account of its nearly globose fruit with inconspicuous ribs and thick corky pericarp. They are natives mostly of the northern hemisphere, with one in South Africa, all growing chiefly in watery places. They are smooth herbs bearing once-pinnate leaves with toothed leaflets, and white flowers in terminal or lateral compound umbels with many-bracted involucres and involucels. They are known as water-parsnip. Two species occur in the eastern United States—S. cicutæfolium and S. Carsonii—besides Berula angustifolia, by many referred here. Compare ninsi, and for S. Helenium see jellico. See cuts under inflorescence and skirret.
