FNA23: "Carex duriuscula belongs to a difficult complex of temperate dry grassland species, and the North American plants are recognized here as conspecific with the Asian Carex duriuscula, following T. V. Egorova (1999). Compared to the Asian plants, the North American plants usually are taller [5–12(–20) versus (6–)10–35 cm] and the perigynia are larger [2.5–3(–3.2) versus 2.4–3.9 mm] (T. V. Egorova 1999). More work is still needed here. North American plants have often been treated as a variety or subspecies of the Eurasian C. stenophylla, which is quite different in having larger perigynia that are distinctly veined adaxially. "
