Shinnersia is an aquatic plant native to Texas and Mexico. It belongs to the boneset tribe within the sunflower family.[2][3]

The genus is named in honor of Lloyd H. Sinners of Southern Methodist University.[2]

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 0.1 meters).[4][5]

Shinnersia is a common freshwater aquarium plant, and can sometimes be found having escaped cultivation.[6]

Species

The only known species in the genus is Shinnersia rivularis, the Rio Grande bugheal[7] or Mexican oak leaf plant, native to Texas, Coahuila, and Nuevo León.[1][2][8] It is thought to be related to two other aquatic genera in this tribe, Sclerolepis and Trichocoronis.[9]
