Description: English: Native and introduced, cool-season, annual, tufted rush to 50 cm tall. Leaves are basal and cauline, shorter than stems, flat and 0.2–1.2 mm wide; sheaths are pale yellow to occasionally red-brown. Flowerheads are diffuse, 2–20 cm long (often much longer than stems); flowers are solitary or clustered (2–4 per cluster) along branches. Tepals are straw-brown, with broad hyaline margins; outer tepals 4.0–8.0 mm long. Capsules are shorter than the tepals and straw-brown to dark red-brown. Flowering is in spring and early summer. A variable species, apparently a mix of naturalized and native forms, widespread in seasonally wet, disturbed habitats. Date: 10 September 2008, 12:54:42.
