R. W. Smith
A weed in Michigan; probably native only to the south and west. Apparently first established in Michigan on the west side of the state (collected in Manistee Co. in 1882, and in several others including Delta Co. in the 1890’s), now widespread in sandy or gravelly soil along roadsides and railroads, in parking lots and fields, and other relatively raw recently disturbed ground.
A hybrid with V. stricta, known as V. ×deamii Moldenke, was collected in Ottawa Co. in 1896. It has the foliage and habit of V. bracteata but much more slender and elongate spikes, with small bracts, as in V. stricta.
