型態特徵

Perennial herbs, monoecious or rarely dioecious. Leaves 3-ranked, radical and/or cauline, with linear or rarely lanceolate blade, base forming a closed sheath; radical sheaths often colored with brown, reddish brown, purple brown or dusky brown, often disintegrating into fibers and covering neck of rhizome. Inflorescence racemose, spicate, fasciculate or paniculate with 2 to many spikes, or a single terminal spike; lateral spikes usually with a utriculiform or ocreiform bracteole (cladoprophyll). Spikes wholly staminate (terminal one), wholly pistillate (lateral ones) or bisexual (androgynous when staminate flowers above, gynaecandrous when female flowers above). Spikelets reduced to a single flower. Staminate spikelets a triandrous naked staminate flower in axil of staminate glumes. Pistillate spikelet a single naked pistil contained in a bottle shaped prophyll (utricle/perigynium). Glumes spirally arranged on a simple axis of spikes, close together; staminate ones bearing an axillary staminate flower; pistillate ones bearing an axillary utricle. Utricles completely closed except at apical orifice through which style and stigma are exserted, 2-costate, nerved or nerveless; lower part (body) dilated, attenuated or contracted above to beaked or non-beaked apex; each utricle subtended by a pistillate glume. Fruit an achene, trigonous with 3 stigmas or lenticular with 2 stigmas, enclosed within utricle.

A variable genus with more than 2,000 species, widespread in both hemispheres. In Taiwan, widely distributed from seashore, swamp, forest floor to high mountain grassland.
