It is closely related and easily confused with Ludwigia hexapetala.[3] The two species can be distinguished at a chromosomal level, because L. grandiflora is hexaploid and L. hexapetala is decaploid.[4] However, they can be distinguished morphologically. L. grandiflora has villous hairs, smaller flowers and smaller pollen grains.[4] Some authorities consider that these differences are too slight to consider these different species and so separate these taxa as two varieties or two subspecies.[5][6]
