Other info. - This common little species can be found mainly in the southern half of Missouri but has also been found in the extreme northeast corner of the state. The plant can be identified by its globose flower clusters, red base, and short, knotty rhizomes. No other species of Cyperus in Missouri has such tight, globose flower clusters. The long bracts which subtend the inflorescence are a good character to look for also.
