Discussion

In the field, Carex scoparia var. tessellata might be confused with the Maine endemic C. oronensis. The two taxa have differing perigynia characteristics and habitats (that of C. oronensis often being drier). Also, the distribution of C. scoparia var. tessellata appears to be near the coast, while C. oronensis occurs throughout much of the Penobscot River Valley and into the upper reaches of the Kennebec River Valley.
