C. subglabrum of Michigan Flora.
Dry ground, railroads, bluffs, roadsides; adventive from farther west and first collected in 1895 in Keweenaw Co.
Referred here are farinose plants with primary leaves very narrow with one main vein and two fine laterals, and pericarp readily separable from the seed. Clemants & Mosyakin (2003) define C. subglabrum as a more western species, essentially non-farinose, and with linear, 1-veined leaves. An immature Kalamazoo County collection (not mapped) may be this, but is too young to determine with certainty.
