Appearance
The plant produces upright, angled stems approaching 1.2 meters in maximum height, growing in beds or colonies from rhizome networks. The inflorescence is a cluster of flower spikes accompanied by a long leaflike bract. The pistillate spikes and sometimes the staminate spikes dangle on peduncles. The fruit is coated by a hard, tough, shiny perigynium which is generally dark in color.References:
