Roots to 15 cm, tip mostly rounded; sheath not winged. Stipes white, small, often decaying. Fronds floating, 1 or 2–5 or more, coherent in groups, ovate, scarcely gibbous, flat, 1–8 mm, 1.3–2 times as long as wide, margins entire; veins 3(–5) (if more than 3, outer ones branching from inner ones), greatest distance between lateral veins near or proximal to middle; papillae not always distinct (one near apex usually larger); lower surface very seldom slightly reddish (much less than on upper), coloring beginning from attachment point of root, upper surface occasionally diffusely reddish; air spaces 0.3 mm or shorter; distinct turions absent. Flowers: ovaries 1-ovulate, utricular scale with narrow opening at apex. Fruits 0.8–1 mm, laterally winged toward apex. Seeds with 8–15 distinct ribs, staying within fruit wall after ripening. 2n = 40, 42 (B), 50, 63, 126.


Phenology: Flowering (rare) late spring–early fall.
Habitat: Mesotrophic to –eutrophic, quiet waters, in suboceanic, cool-temperate regions with relatively mild winters
Elevation: 0–2000 m

Discussion

Indication of this species in Newfoundland (H. J. Scoggan 1978–1979) probably refers to Lemna turionifera.

A specimen in the Gray Herbarium from St. Pierre and Miquelon may represent Lemna minor or L. turionifera; its determination is questionable.

Selected References

None.
