Flowering - April - October.

Habitat - Waste places, lawns, roadsides, railroads.

Origin - Native to Eurasia.

Other info. - This introduced species is rare in Missouri. It is much more abundant in the southeastern U.S. and in the tropical Americas. Steyermark only reported it in two counties at the time of his book. It is likely that the plant will spread over time.
This species is easy to identify because of its small yellow flowers and coiled fruits, which have bristled margins. Another species, M. arabica (L.) Huds., is similar but typically has a dark central splotch on each leaflet and has stipules which are not cut as deeply as those of M. polymorpha.
