    Leaves few-to-many per culm, cauline, 3-ranked;
    ligules usually well developed, sometimes obsolete;
    blades well developed (or rudimentary, sometimes absent on proximal leaves), shorter than, equaling, or overtopping culms, plane, keeled, or revolute, 0.5–9 mm wide, stiff, with prominent midvein, glabrous, scabrous, or pubescent.
    Inflorescences terminal, often axillary, sometimes pseudolateral, panicles, spikes, or 1 or more capitate or fasciculate clusters;
    spikelets 1–100+;
    bracts 1–3, ascending or erect, bristle-shaped, awl-shaped, or leaflike, sometimes appearing to continuation of culm, 10–150 mm, shorter than or exceeding spikelets, glabrous or ciliate.
    Spikelets: scales 3–10+, each subtending flower, distichous, proximal 2–4 scales empty, proximal fertile scale pistillate, distal fertile scales staminate or sometimes empty;
    occasionally some spikelets entirely pistillate or staminate.
    Flowers unisexual;
    anthers 2–4 mm, apex usually mucronate or awned;
