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

Jones' 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 loosely cespitose, 15–40(60) cm tall, with basal sheaths of previous years persisting as fibers.
Leaves

(1.5)2– 3.5(4) mm wide.

sheath fronts hyaline, usually smooth, occasionally somewhat cross-corrugated; shorter than the blades, with mouth concave; all or most sheaths with well-developed blades;

blades 1–4 mm wide, green; all clustered near the base of the shoot, arising at about the same height so that the sheath fronts are mostly hidden.

Inflorescences

1.5–4 cm × 10–15 mm; erect to flexuous, not head-like; the lower spikes somewhat separated;

spikes gynaecandrous.

0.8–2(2.5) × 0.6–1.5 cm; dense and head-like;

spikes all androgynous, or some female.

Perigynia

3.4–4.7(5.2) × 1.3–2.1 mm; straw-colored or light brown, with 3–9 conspicuous dorsal veins and 2–5 conspicuous ventral veins;

wings 0.2–0.5 mm wide;

beak brown; parallel-sided; entire for the distal 0.3–0.5 mm (occasionally winged almost to the tip); (1.2)1.5–2 mm from achene top to beak tip;

stigmas 2.

2.5–3.5(4) × 1–1.5 mm; widest near the base (occasionally near middle), brown, strongly veined, with 7–11 veins on the dorsal surface, 5–7 on the ventral surface;

base usually pithy and strongly swollen;

beak 0.5–1.5(2) mm long;

margins smooth or nearly so;

stigmas 2.

Achenes

lenticular, 1.1–1.8 × 0.9–1.2 mm, 0.4–0.5 mm thick.

lenticular.

Female scales

3.4–5 mm long; longer or shorter; wider or narrower than the perigynia; straw-colored, brown or green;

margins not white-hyaline; the tip often white-hyaline; acute to acuminate.

about as long as the perigynia, dark brown.

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.

Wet meadows, seeps and streamsides in the mountains. 600–2800 m. BR, BW, Casc, ECas, Sisk. CA, ID, NV, WA; northeast to MT. Native.

Carex jonesii is a common “ball-headed” sedge of montane wetlands, sometimes referred to as the big butt sedge because of its swollen, pithy perigynium bases. Carex jonesii often grows with C. neurophora, which has more or less cross-corrugated leaf sheath fronts that are usually exposed because the leaves arise at different heights. In southwestern Oregon, see C. nervina.
