Fruits:
Perigynia egg-shaped, 4.5-5 mm long, 1.8-2.3 mm wide, straw-coloured or brown, inflated, smooth, shiny, membranaceous, nerveless, short-stalked, the beaks short, bidentate; female scales egg-shaped, usually slightly shorter than the perigynia, sharp-pointed or awned, reddish-brown, brown or straw-coloured, the centres lighter, the margins translucent; stigmas 3; achenes 3-angled, 1.2-1.5 mm long.
