In the 14 years prior to 1982, H. morsus-ranae increased its area of occurrence in North America by 3 times. Although it differs from most other North American aquatics in having very rounded leaves with five prominent and converging primary veins, these characters do not distinguish it from floating-leaved forms of Limnobium spongia.
