Knautia macedonica Griseb. Dipsacaceae. Distribution: Macedonia. This honours the brothers Knaut, both physicians and botanists: Christof Knaut (also Knauth, 1638–94) and his brother Christian Knaut (1654–1716). The plant was traditionally used as a compress in its native Balkans to relieve dermatitis and itching. This use is a local survival of what was once a widespread application of this plant and its relations, and is an example of the doctrine of signatures in which the therapeutic benefit of a plant is suggested by some aspect of its anatomy
