Rumex brownii, the hooked dock, Browne's dock or swamp dock, is a leafy perennial herb native to Australia, and is widespread and grows in disturbed sites. It is an introduced weed in the Pacific Islands, England,[1] Japan, and New Zealand.[2]
It is 50–80 cm high with variably shaped basal leaves, oblong or lanceolate, to 12 cm long, and to 4 cm wide with cordate to truncate base. The petiole is about half as long as the lamina. Flower whorls with 3–5 hooked teeth on each side and with a hooked tip.[3] The hooks aid seed dispersal via attaching to animal fur and hair, and also human clothing.[4]
Leaf used as a blanched leafy vegetable.
