Genera 4, species ca. 175 (2 genera, 9 species in the flora).
Droseraceae comprise carnivorous plants with an unusual, worldwide distribution. They live mostly in sunny, low-nutrient, moist-to-wet acidic sands, clays, seeps, and peat bogs, often subjected to periodic fires. They catch rather small prey in jawlike traps (Aldrovanda Linnaeus and Dionaea) or on sticky glandular hairs (Drosera and Drosophyllum Link). All genera, except Drosera, are monotypic and sometimes have been placed in separate families for various reasons. F. Rivadavia et al. (2003) indicated that Droseraceae are monophyletic including these three genera but excluding Drosophyllum; K. M. Cameron et al. (2002) believed that the Old World Aldrovanda is more closely related to Dionaea, and both genera are relicts of a more widespread distribution based on fossil pollen records.
Some species of Droseraceae are grown worldwide as ornamental bog garden or terrarium specimens and as such have been given formal or informal cultivar names. Species of Drosera have been artificially hybridized for horticultural purposes; in the wild the rare hybrids that do occur are normally sterile.
