Staminate flowers not separately bracteolate, but with linear bracts subtending each spike; perianth 4(-5)-lobed; stamens 4-5. Pistillate flowers each enclosed by 2 bracteoles connate nearly to apex; perianth absent; stigmas 2. Fruiting structures: bracteoles either veinless and laterally flattened and/or 1-3-veined adaxially, or rarely unequally 3-winged, enclosed achene vertical, or bracteoles transversely flattened, oval to hexagonal and not or unequally 1-4(-5)-ridged , with 2 slightly enlarged wings, thus accommodating horizontal achene, margins not spongy-thickened; bracteoles lacking spongy cellular matrix, often subtended by single, filiform bractlet; pericarp adherent.
