Rumex dentatus L. | |
Rumex dentatus is a species of flowering plant in the knotweed family known by the common names toothed dock[1] and Aegean dock. It is native to parts of Eurasia and North Africa, and it is widely known elsewhere as an introduced species and a common roadside weed. It grows in disturbed habitat, often in moist areas, such as lakeshores and the edges of cultivated fields. It is an annual or biennial herb producing a slender, erect stem up to 70 or 80 centimeters in maximum height. The leaves are lance-shaped to oval with slightly wavy edges, growing to a maximum length around 12 centimeters. The inflorescence is an interrupted series of clusters of flowers, with 10 to 20 flowers per cluster and each flower hanging on a pedicel. Each flower has usually six tepals, the 3 inner of which are edged with spinelike teeth and have tubercles at their centers.
This plant has allelopathic activity,[2] producing substances that inhibit the growth of other plants near it, as well as antibacterial and antifungal activity.[3]
