Patersonia
''Patersonia'', commonly known as native iris or native flag and are native to areas from Malesia to Australia. 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 gynoecium, style, which bears a flattened carpel, stigma.Goldblatt, P. (2011). Systematics of ''Patersonia'' (Iridaceae, Patersonioideae) in the Malesian archipelago. Annals of the Missouri Botanical Garden 98: 514-523.

Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...
