Isatis is a genus of flowering plants in the family Brassicaceae, native to the Mediterranean region east to central Asia. Its genus name, Isatis, derives from the ancient Greek word for the plant, ἰσάτις. The genus includes woad (Isatis tinctoria). Due to their extremely variable morphology, the Asian species in particular are difficult to determine; the only reliable diagnostic feature is the ripe fruit. They are (usually) biennial or perennial herbaceous plants, often bluish and hairless or downy hairy with the upright stem branched.[2]
