The Cabombaceae are a family of aquatic, herbaceous flowering plants. A common name for its species is water shield.[1] The family is recognised as distinct in the Angiosperm Phylogeny Group IV system (2016). The family consists of two genera of aquatic plants, Brasenia and Cabomba, totalling six species.[2]

Distribution

The Cabombaceae are all aquatic, living in still or slow-moving waters of temperate and tropical North and South America, Europe, Asia, Africa, and Australia. Although found on all continents but Antarctica, the plants tend to grow in relatively restricted ranges.[3]

Fossil record

The family has an extensive fossil record from the Cretaceous with plants that exhibit affinities to either the Cabombaceae or Nymphaeaceae occurring in the Early Cretaceous.[3]

One such likely Cretaceous member is the genus Pluricarpellatia, found in rocks 115 million years old in what is now Brazil.[4]

Scutifolium jordanicum David W.Taylor, G.J.Brenner et S.H.Basha has been described from the lower cretaceous of Jordan.[5]

Taxonomy

Publication

The family Cabombaceae Rich. ex A.Rich. was first published in 1822 by Louis Claude Richard, but initial description did not satisfy the requirements for valid publications. The family then was validated by Achille Richard.[6]

Taxonomic history

The APG system of 1998 included this family in the water lily family Nymphaeaceae, as did the APG II system, of 2003 (optionally). The APG III and APG IV systems of classification separated the family Cabombaceae from the family Nymphaeaceae.[7][8][9] The family is part of the order Nymphaeales, which is one of the most basal flowering plant lineages.
