Panicum gattingeri spikelet pairs B. S. Walters spikelet pairs

Roadsides, fields, sandy or muddy shores.

This species can occur in weedy habitats, but is also characteristic of sandy and muddy shores of streams and lakes. It is apparently confined to the southern half of the Lower Peninsula and though presumably native, was first collected by R. W. Smith in Lenawee Co. as recently as 1985. Part of the P. philadelphicum concept as broadly conceived in Michigan Flora and united by some with P. philadelphicum as subsp. gattingeri (Nash) Freckmann & Lelong.
