The long-stalked, linear-oblong, often floating leaves have prominent midribs. Whorls of shallowly cup-shaped, white or pink flowers are borne in umbels, racemes, or panicles. The clusters of ellipsoid fruits grow in radiating, star-like whorls, hence the common name. Grow in the shallow margins of a small pool.
