Description Root a rhizome creeping bearing tubers. Culms trigonous striate 1–1.5 m. high 4–5 mm. broad, uppermost portion scabrid. Leaves cauline, grasslike, tapering, scabrid above on margins and midrib, 6–8 mm. broad, 45 cm. long or more. Inflorescence a terminal umbel of 4–6 unequal rays bearing 3–6 spikelets with a glomerule of sessile spikelets below. Spikelets 10–15 mm. long, ovoid to cylindric subacute, the whole subtended by an involucre of leaf-like scabrid, unequal bracts, as many as or 1–2 fewer than the rays 20–27 cm. long 3–5 mm. broad, longest erect, the remainder oblique. Bractlets glumelike at base of spikelets, with narrow scabrid, erect awns; glumes pubescent, tips cleft or lacerate, midrib produced into scabrid recurved awn. Stamens 3, tips of anthers pointed, scabrid. Styles 2 and 3 fid in the same spikelet, the latter usually predominating; perianth bristles 5–6 unequal retrorsely scabrid about ½ length of the achene, somewhat deciduous. Achene broadly obovoid, flat on one side, convex or obtusely angled on the other, shiny, shortly pointed, almost black when mature. Plano convex nuts 3–5–4 mm. long, 2–5 mm. broad; obtusely trigonous nuts 3–5–4 mm. long, 2–2–2.5 mm. broad. [details]

Abundant in ditches on the Hauraki Plains and probably the most common of the species [details]
