Galium album A. A. Reznicek

G. mollugo of Michigan Flora.

A Eurasian native, locally established along trails, roads, and fencerows; in other disturbed ground; sometimes a garden weed. First collected in 1895 in Bay Co.

Though no chromosome counts are known from Michigan material, our few collections all have well pressed corollas ca. 3–5 mm in diameter and the pedicels at anthesis shorter than the corolla width and appear to be the tetraploid segregate Galium album, rather than the smaller-flowered diploid G. mollugo, a plant of more Mediterranean distribution in Europe.

Depauperate or lax plants might be confused with G. concinnum, but the latter never has more than 6 leaves in a whorl even at the principal nodes of the main stem, and the leaves are nearly or quite linear. Known to hybridize with G. verum, but such hybrids have not been detected in Michigan.
