common name for the Pontederiaceae, a family of chiefly tropical perennial aquatic herbs found in freshwater. The pickerelweeds (genus Pontederia) range north into temperate regions, including most of the E United States and Canada. The water hyacinth (Eichhornia crassipes), a native of tropical America, has spread widely and is so prolific that it has clogged many waterways in the S United States and in other areas, including Java, Australia, and the Great Lakes region of E Africa. It is sometimes cultivated in tanks and ponds for its ornamental foliage and blue-violet flowers. The pickerelweed family is classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).
