Myosurus minimus Linnaeus. Mousetail. Phen: Mar-May. Hab: Usually in disturbed areas, such as fields in floodplains. Dist: The species is circumboreal and also found in various places in the Southern Hemisphere. Widely distributed in North America, Eurasia, and the Southern Hemisphere. The pre-Columbian occurrence of Myosurus in parts of our area (such as the Coastal Plain and Piedmont of the Atlantic states) is uncertain; it may well be an alien, early introduced from more western parts of se. North America.

Origin/Endemic status: Native

Taxonomy Comments: A number of subspecies have been described; if these are recognized, our material in eastern North America is the typic ssp. minimus.

Other Comments: The plant is a winter annual, sprouting from seed in the fall, overwintering as a rosette, and flowering in early spring.
