|discussion=<p><i>Azolla filiculoides</i> is cold tolerant, surviving even in fragmented parts under thin ice. It usually reaches a climax population in late spring, becomes fertile, collapses, and is replaced by other more heat-tolerant aquatics such as <i>Lemna</i> spp. Hybrids between this species (male) and <i>A. microphylla</i> Kaulfuss (female), a species of Central America, South America, and the West Indies, have been reported (Do V. C. et al. 1989). V. M. Bates and E. T. Browne (1981) reported <i>A. filiculoides</i> from Georgia, far removed from its main range in western North America. The most likely explanation is that the plants represent escapes from horticulture.</p>
