    Pantemperate and tropical
    Herbs, perennial or less often annual, cespitose or not, rhizomatous, stoloniferous, rarely tuberous.
    Culms solitary or not, trigonous or round, glabrous or scabridulous with extrorse or antrorse (rarely retrorse) prickles.
    Leaves usually basal;
    blades keeled abaxially, flat, V, or inversely W-shaped in cross-section.
    Inflorescences terminal, rarely pseudolateral, 1st order subumbellate to capitate, 2d order with spicate or digitately arranged spikelets, rarely a solitary spikelet;
    1st order rays unequal (rarely equal) in length, produced singly from the axils of inflorescence bracts;
    involucral-bracts 1–22, spirally arranged at culm apex, spreading to erect, leaflike.
    Spikelets: scales to 76, distichous, each subtending flower, cylindric to compressed, borne spicately or digitately at ends of rays (occasionally proliferous).
    Flowers bisexual [rarely unisexual], in axils of distichous floral scales, bases often decurrent onto rachilla as ± hyaline wings;
    styles linear, 2–3-fid, base deciduous or persistent;
    Achenes biconvex, flattened, or trigonous.
