Carex artitecta, Carex emmonsii
A. A. Reznicek
In Michigan, var. albicans (C. artitecta of Michigan Flora), with staminate scales ± obtuse or broadly acute, the midrib usually weak or absent just below the tip, and culms ± erect and usually surpassing the leaves, occurs in sandy hardwoods, mostly in southwestern Michigan. Carex albicans var. emmonsii (Torr.) Rettig (C. emmonsii of Michigan Flora) has staminate scales narrowed to a sharp, often slightly scabrous tip [15×], the midrib prominent to the end or even slightly excurrent, and the culms weak, usually loosely spreading or arching and usually shorter than the leaves; it is more widespread than var. albicans and occurs in moist to dry acidic, sandy or peaty open or shaded ground, often on hummocks and near wetlands.
