See text Cabomba is a genus of perennial, rhizomatous, aquatic herbs in the family Cabombaceae[3] native to tropical and subtropical America.

[2] It has divided submerged leaves in the shape of a fan (hence the vernacular name fanwort) and is much favoured by aquarists as an ornamental and oxygenating plant for fish tanks.

[11] The solitary,[7] hermaphrodite, pedicellate,[3][7] chasmogamous, scentless, actinomorphic,[3] white, yellow, or purple,[9] trimerous or rarely di- and tetramerous flowers extend beyond the water surface.

[16] By contrast, Cabomba furcata is considered to be difficult to cultivate in the aquarium, as it requires soft, acid water and a high light intensity.

[17][18][19] Use in the aquarium trade has led to some species being introduced to other parts of the world, such as Australia, where Cabomba caroliniana it is a nationally declared weed.

[20] Having arrived in 1967, it spread rapidly in waterways and out-competed native plants, threatening water supplies, especially along the eastern side of the continent.

[24] Likewise, Cabomba furcata has become an invasive species in Kerala, India,[25][26] in the Kalutara district of Sri Lanka,[27] in Chini Lake, Malaysia,[28] and Taiwan.
