Overview

Hippuris, the mare's tail, was previously the sole genus in the family Hippuridaceae. Following genetic research by the Angiosperm Phylogeny Group, it has now been transferred to the family Plantaginaceae, with Hippuridaceae being reduced to a synonym of Plantaginaceae.

Fourleaf mare's tail is critically endangered due to its extremely limited distribution and vulnerability to habitat degradation. The species faces severe threats from human activities that alter or destroy its specialized aquatic and wetland habitats. Climate change and water management practices pose additional risks to this rare aquatic plant's survival.
