Some species, especially in ponds and very slow-moving waters, have floating leaves which tend to be opaque with a leathery texture. Leaf shape has been found to be highly plastic, with variability due to changes in light, water chemistry, planting depth, sediment conditions, temperature, photo period, waves, and seasonality.

seeds are viable after passing through the digestive tracts of birds and this mechanism is probably the only natural mechanism for long-distance dispersal between isolated water bodies. Vegetative propagation occurs by a variety of mechanisms including turions, and via growth and fragmentation of rhizomes and shoots. Vegetative reproduction is evidently an effective means of ensuring local persistence, as sterile hybrids have been recorded at some sites for over 100 years.

The flowers, which are often overlooked, are greenish-brown and are composed of four rounded segments borne in a spike. They are 2–4 merous, with superior ovaries and anthers that turn outward. The fruits are spheroidal and green to brown, usually 1–3 mm in diameter, with a noticeable 'beak'.

Reproduction of pondweeds occurs both vegetatively and by seed, though studies suggest that in some species or situations reproduction by seed is rare. The fruits may be produced in large quantities from midsumer onwards, and are ingested by waterfowl. Germination experiments have shown that the

flora was subsequently named during the late 18th and early 19th century. As botanists ventured further afield, pondweeds began to be collected and named from other parts of the world. The North America flora was largely named by the start of the 20th century. Alfred Fryer became interested in

populations show very low infrapopulation diversity, especially when living in deep, shaded or turbulent water where colonies do not expend energy on flowers. This has made it very difficult to use genetic data to find patterns of geographical differentiation.

Although they occur in a range of environments, most species prefer standing or slow-flowing waters with some calcium and fairly low nutrient levels. In general the fine-leaved species are more tolerant of human impacts such as
