Patersonia
Template:Short description Template:Automatic taxobox
Patersonia, is a genus of plants whose species are commonly known as native iris or native flag and are native to areas from Malesia to Australia.[1]
Description
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, often with adaptations for conserving moisture, such as stomata sunk in grooves, a thickened cross-section, marginal hairs, and 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.[2]
Taxonomy
The genus Patersonia was first formally described in 1807 by Robert Brown in the Botanical Magazine.[3] The genus name is a tribute to the first Lieutenant Governor of New South Wales in Australia, William Paterson, "a gentleman whose name has been long familiar to the naturalist".[4][5]
