mare's-tail, any plant of the genus Hippuris, perennial, submerged aquatic herbs of temperate and frigid regions. Mare's-tails have an erect stem bearing whorls of small leaves, so they resemble some of the horsetails (which are also sometimes called mare's-tails); however, unlike horsetails, they are flowering plants, with the inconspicuous flowers borne in the leaf axils. Mare's-tails are cultivated in bog gardens. They are classified in the division Magnoliophyta, class Magnoliopsida, order Callitrichales, family Hippuridaceae.

Species

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 synonymy under Plantaginaceae.

It includes one to three species depending on taxonomic interpretation. Some authorities only accept the first species of those listed below, treating the other two as synonyms of it:

  • Common mare's tail, Hippuris vulgaris
    • Mountain mare's tail, Hippuris montana
    • Fourleaf mare's tail, Hippuris tetraphylla

They are aquatic plants found in shallow ponds and streams, both slow-moving and fast-flowing. This flowering plant is sometimes mistakenly identified as the non-flowering horsetail.
