Patersonia (or '''Purple flag''') is a genus of the Iridaceae with about 20 species in Australia and at least one in Timor . They are perennials with basal leaves growing from a woody rhizome that in some species extends above ground to form a short trunk. The leaves are tough and fibrous with various adaptations to conserve moisture: Stomata sunk in grooves, thickened cross-section, marginal hairs or thickened margins. The flowers appear from between a pair of Bracts on a leafless stem. They have three large outer Tepals that are usually blue to violet, and three tiny inner tepals. There are three Stamens fused at the base to form a tube around the longer style which bears a flattened Stigma . Several species are grown as garden subjects. They can be propagated by seed or by division.
