Generative characteristics

The granulose, pilose, ellipsoid seeds feature trichomes in longitudinal, interrupted lines.[3]

Cytology

The diploid chromosome count is 2n = 28.[8][9][10]

Reproduction

Vegetative reproduction

Stolons and proliferating pseudanthia are absent.[8][10][3]

Generative reproduction

Water disperses the seeds (i.e. hydrochory).[9]

Habitat

It grows in various freshwater habitats, such as marshes, canals, shallow waters, flooded ditches, flooded flatwoods, ponds, slowly flowing streams, and lakes.[11][8][10][5][12] It is intolerant of saltwater.[5]

It is placed in Nymphaea subgenus Hydrocallis.[8]

Etymology

The specific epithet jamesoniana honours the Scottish botanist William Jameson (1796-1873).[11]

Conservation

In Puerto Rico, USA it faces habitat destruction.[14] The NatureServe conservation status is secure (G5).[1] In Florida, USA it is considered to be endangered.[12][15]

Uses

Nymphaea jamesoniana has been employed in the treatment of conditions such as irritated eyes, dysentery, and skin lesions. It has been utilized for its astringent properties. There are claims that its flowers possess narcotic properties.
