Carex pauciflora Lightf.
Common Name: SEDGE
Coefficient of Conservatism: 10
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt P-Sedge

One of the most distinctive species of this genus, frequent in sphagnum bogs in the northern part of the state, more local southward; usually on open mats.

When fully mature, reflexed perigynia of this remarkable species are "spring loaded" and will pop off when touched, sometimes landing a meter or more away from the stem. Needless to say, making specimens of this plant with mature perigynia is a surprising and peculiar endeavor. 

The Washtenaw Co. specimen (MICH) has no data, but the species is noted in old records for Ann Arbor and a "sphagnum bog 2 miles W & S of Whitmore Lake" and Walpole's Flora of Washtenaw Co. also reports this plant.  It imay be that this collection is a voucher for one of these citations where the data has been lost.
