The common name for the red seaweed Laurencia pinnatifida (family Rhodomelaceae, order Ceramiales). The seaweed is variable in form and colour. When growing in bright sunlight on the upper shore, it usually grows in short, dense tufts and is yellowish-green in colour; but when growing further towards the low-water mark it is larger and dark reddish-purple. The plant is generally flattened and extensively branched in one plane. It has a strong, distinctive, pungent smell, and a peppery taste. It has been used as a condiment in some areas.
