eggbract sedge, hare sedge, oval broom sedge, oval sedge

weak-veined sedge

Habit Plants cespitose, (24)35–85 cm tall at flowering; vegetative shoots elongating late in the season and becoming stolons (developing shoots and roots at the nodes), sprawling over shorter vegetation. Plants cespitose; culms 10–83 cm long, smooth or more often papillose (at 20×) at mid-length, the fragile papillae like tiny pegs projecting at right angles to the culm on its edges.

spikes gynaecandrous.

spikes (4)5–6(7) usually longer than wide, generally pale to straw-colored; smooth or rough in outline, usually gynaecandrous, sometimes male or female; lowest spike 9.5– 18 mm long, with 11–22 perigynia; terminal spike 9.5–16 mm long.

Discussion

Moist meadows and wet prairies at low elevations. 50–1400 m. CR, Sisk, WV. CA, NV, WA; north to British Columbia, WI to Prince Edward Island south to KY and NC; Australia, Eurasia, New Zealand. Native.

Carex leporina is a loosely tufted sedge with a light brown, somewhat elongate inflorescence. The stolons form late in the season and are rarely collected. Similar C. praticola has female scales with white margins. Its perigynia are veinless or weakly veined on the ventral surface, have longer beaks that are brown, parallel-sided, and wingless for the distal 0.4–1 mm and have the very tip narrowly white-edged.

Shaded to partially shaded riparian zones in mountains. 600–2000 m. BW, Casc, ECas, Sisk. CA, ID, NV, WA; north to British Columbia, northeast to MT. Native.

This is one of the “identical triplets,” distinguished by its relatively long beaks and short beak teeth. See discussion under C. bolanderi.
