Monochoria korsakowii is a species of annual flowering plant in the water hyacinth family known by several common names, including heartleaf false pickerelweed and oval-leafed pondweed.

It is found in lakes, ponds, swamps, and rice paddy fields.

[1] It is native to east Asia, although it is endangered in Japan due to excessive use of acetolactate synthase-inhibiting herbicides.

[2][3] In China, it has become a significant threat to rice production, particularly in Liaoning province, where it has evolved high levels of resistance to the herbicide bensulfuron-methyl.
