2.5 mm long, the backs hispidulous
and sparingly strigose, medially 3-nerved, these converging to form a spreading-ascending mucro to 2.5 mm long.
Also, the perigynia of bog plants are, in general, longer and narrower than those of grassland plants; additionally, the perigynia of the former are smooth except sometimes sparingly hispidulous
just beneath the beak, whereas those of the latter are distinctly appressed hispid above the middle of the perigynium.
