However, the very large leafy bracts that are clustered below the seed-heads (i.e. The true leaves are reduced to long sheaths that cover the bases of the stems. They are hairless and sometimes slightly ridged lengthwise. erect) stems (3-5 mm thick) are rigid and triangular to almost cylindrical in cross-section (i.e. Īt the tips of these branches are clusters of elongated flower spikelets that turn reddish-brown as they mature.The seed-heads have about eight main branches (5-10 cm long) radiating from the top of the stem. these branched seed-heads are subtended by many green leafy bracts that have an umbrella-like appearance.it produces several upright stems (up to 120 cm tall) topped with large seed-heads.a reed-like plant with basal leaves reduced to sheaths.erect) stems usually growing 45-120 cm tall, but occasionally reaching up to 1.5 m in height. perennial) reed-like plant with upright (i.e. ![]() creeks, wetlands, swamps, drainage channels and ditches) in tropical, sub-tropical and warmer temperate regions. southern USA, Hawaii, numerous Pacific islands and New Zealand).
