Dyssodia papposa head A. A. Reznicek head

A strongly fetid plant  native well west of Michigan in the south-central Great Plains and first collected in Kent Co. in 1902 by E. J. Cole. Not found again until 2003, when noted as abundant along the gravel shoulder of US 23 in Monroe Co. 

This plant is doubtless more widespread than collections suggest, and is rapidly spreading along gravel highway shoulders, especially along expressways.
