It is classified in tribe Eupatorieae within family Asteraceae.[3][4][1][5] It is thought to be related to two other aquatic genera in this tribe, Sclerolepis and Trichocoronis.[6] The roots live in the muck at the bottom of shallow slow-moving water (for example, along a stream), and the stem extends above the water slightly (less than 10 centimetres).[7][8]
Shinnersia is a common freshwater aquarium plant, and can sometimes be found having escaped cultivation.[9] The genus is named in honor of Lloyd H. Shinners of the Southern Methodist University.[3]
