Discussion

Stenanthium gramineum shares molecular affinities with the Zigadenus densus (Desrousseaux) Fernald and Z. leimanthoides A. Gray species pair (W. B. Zomlefer et al. 2001).

The varieties of Stenanthium gramineum recognized by M. L. Fernald, but not here, are indistinct and sympatric (R. R. Gates 1918; R. G. Johnson 1969). The disjunct upper Michigan localities represent locally established waifs (E. G. Voss 1972–1985, vol. 1).
