From Flora of Indiana (1940) by Charles C. Deam

Our Clark County specimen is from a fallow field and that from Martin County is from a wheat stubble field. Pepoon reports it as found in Lake County along the Wabash Railroad at Miller. Kriebel has collected it in Lawrence County and in 1929 Bechtel collected it in Montgomery County. This species also seems to be adventive from the south.
