The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Mentha aquatica L.

Common name: water mint

Synonyms and Other Names: Mentha citrata Ehrh., Mentha piperita spp. citrate (Ehrh.) Briq., Mentha X piperita var. citrate (Ehrh.) Briq, Mentha X piperi var. citrata (Ehrh.) B. Boivin (pro nm.), water mint, lemonmint

Taxonomy: available through www.itis.govITIS logo

Identification: Water mint is an herbaceous rhizomatous perennial plant growing to 90 cm tall (Source: Wikipedia). The stems are square in cross section, green or purple, and variably hairy to almost hairless. The rhizomes are wide-spreading, fleshy, and bear fibrous roots. The leaves are ovate to ovate-lanceolate, 2–6 cm long and 1–4 cm broad, green (sometimes purplish), opposite, toothed, and vary from hairy to nearly hairless. The flowers are tiny, densely crowded, purple, tubular, and pinkish to lilac in color. All parts of the plant have a distinctly minty smell.

Size: to 90 cm

Native Range: Eurasia, northwest Africa and southwest Asia.

Ecology: Water mint occurs in the shallow margins and channels of streams, rivers, pools, dykes, ditches, canals, wet meadows, marshes and fens (Warren 1993). If the plant grows in the water itself, it rises above the surface of the water. It generally occurs on mildly acid to calcareous (it is common on soft limestone) mineral or peaty soils. Flowering is from mid-late summer. Water mint is pollinated by insects, and also spreads by underground rhizomes, like other species of mint.

Means of Introduction: Deliberate release.

Status: Established.

Remarks: It hybridises with Mentha spicata (Spearmint) to produce Mentha × piperita (Peppermint), a sterile hybrid; with Mentha suaveolens (Apple Mint) to produce Mentha × suavis; with Mentha arvensis (Corn Mint) to produce Mentha × verticillata; and with both M. arvensis and M. spicata to give the tri-species hybrid Mentha × smithiana.
