Xanthium strumarium L.

Common Name: COMMON COCKLEBUR
Coefficient of Conservatism: 0
Coefficient of Wetness: 0
Wetness Index: FAC
Physiognomy: Nt A-Forb

A nearly cosmopolitan weed of disturbed area, but also on shores of rivers and lakes, and moist openings in floodplains. Tentatively considered at least in part native as it was collected as early as 1838 by the First Survey in St. Joseph Co.

Numerous species have been segregated in the past but are now generally recognized as part of the variable X. strumarium.
