Spikes 3 to 5, 4-10 mm long, the terminal spike entirely with male flowers or with a few female flowers at the the top, the lateral spikes 2 to 4, with female flowers, short-stalked; bracts subtending the female spikes short-sheathing, leaflike, the lowermost equalling or slightly surpassing the inflorescence.
