Hydrocotyle consists of plants ordinarily small, herbaceous, aquatic, often perennial, rarely subshrubby at the base. The perennial species generally have a slender stock creeping on the moist soil or in the mud, sending out adventitious roots at the nodes. The leaves are alternate, petiolate, entire, or crenelate, digitinerved or palmatisect, not unfrequently peltate, rarely narrow and elongate, uninerved. They are accompanied at the base by scarious stipules,^ entire or laciniate, sometimes none. The flowers,' hermaphrodite or poly- gamous, are arranged in a very variable manner at the nodes of the stem or at the end of the branches.
