Was a bit interesting to scour all the thickets near the river mouth without luck then find this species growing on the rock pile under the bridge. Traits of "f. psila" and typical form intergraded on this individual, which was interesting. And problematic.

"A form with the leaves glabrate beneath, and often with twigs scarcely if at all glaucous [f. psila C. K. Schneid.] is frequent along the north shore of Lake Superior in Ontario and has been collected on the upper beach of Lake Superior in Luce Co." (https://michiganflora.net/species.aspx?id=2635)

Less than a week after the first state record found by @alexgraeff. All awns <5mm; fruiting stage less advanced than sympatric E. virginicus; lower leaves short & senescing early; upper leaves erect or at least not spreading or drooping. Widely and sparsely scattered within 20 meters of river. Last photo is a comparison with E. virginicus (E. curvatus on right).

Collected. These coordinates were taken from my phone in the field.

Habitat, size, color suggest this over F. asagrayana, though unfortunately no bracts to examine to be certain of that differentiation

Reaaalllly interesting occurrence on lower portion of dry sandstone bluff over Sturgeon River, only in spots where a loose accumulation of sand had formed from upslope erosion. Much better argument for nativity here than the other Michigan collection.
