    sheath fronts membranous, sheaths of proximal cauline leaves smooth or very weakly transversely rugose, sheaths of distal leaves with at least narrow hyaline or white-hyaline band;
    blades V-shaped in cross-section when young, widest 0.8–5 mm wide, glabrous.
    Inflorescences racemose, with (1–) 2–10 spikes;
    bracts sheathless, with inconspicuous blades, at least (1.5–) 2 times as long as wide;
