About Rumex brownii Campd.
Rumex brownii Campd., commonly known as hooked dock, Browne's dock, or swamp dock, is a leafy perennial herb. It is native to Australia, where it is widespread and grows in disturbed sites. It has been introduced as a weed to the Pacific Islands, England, Japan, and New Zealand. This species reaches 50 to 80 centimeters in height, and has variably shaped basal leaves that are oblong or lanceolate. Mature basal leaves grow up to 12 centimeters long and 4 centimeters wide, with a cordate to truncate base. The leaf petiole is approximately half as long as the leaf blade. Each side of its flower whorls has 3 to 5 hooked teeth, and the whorls also have a hooked tip. These hooks help the plant disperse its seeds by attaching to the fur of animals and human clothing. Its leaves are used as a blanched leafy vegetable.
