Agrimony
Agrimony, the popular name of the small genus Agrimonia, in the order Rosaceae. It includes eight or ten species, widely distributed, two being British. They are perennial herbs with pinnate, sometimes lyrate, leaves, and racemes of short, stalked, small, yellow flowers. The floral leaves are in fives, but there are only two carpels, and in some species, such as A. odorata, there are subsidiary rows of stamens. The rhizome is astringent and yields a yellow dye, and the bruised leaves are aromatic and reputedly tonic. Hemp-Agrimony is the popular name of the Composite Eupatorium cannabinum, a very different plant.
