The Short Story of Swainsona

Svaynsona (genus Swainsona) - a large genus of legumes of Australasia. It includes 85 species, of which 84 - Australian endemics, one - Swainsona novae-zelandiae - found only in New Zealand.

Attributed to the tribe Galegeae, born Swainsonia forms put to New Zealand genera Montigena, Clianthus, and Carmichaelia.

The genus is named after English botanist Isaac Svaynsona (English) Russian. The plant is known by its unique blood-red leaves, and flowers, with a bulbous black serdtsevinkoy.

This is one of the most famous field of flowers in Australia. Its usual habitat - dry areas of central and north-western Australia, and its range extends to all Australian states except Victoria.

Samples Svaynsony were first collected by William Dampier, who recorded his first observations of 22 August 1699. These samples are now in the Fielding-Druce Herbarium at Oxford University in England.

In the 18 th century plant called Cliantus dampieri, and later became more widely known as Formosa Clianthus (Formosa is Latin for "beautiful"). However, later sand beauty was classified in the family Fabaceae entitled Swainsona formosa.

Further reclassification Formosa Willdampia was proposed in the publication Western Australian Naturalist in 1999, but this proposal was rejected by the scientific community in 2000.

Time of bloom - spring and summer, especially accelerating the emergence of color after the rain. Most species of plants stunted or prostrate, but in the Pilbara region in north-western Australia were found copies of the height of 2 meters.

Generally svaynsona not considered a plant longevity, but it can prolong life, if conditions are favorable. If you do not touch the roots, flowering may resume in the next season.

Svaynsona well adapted to life in the desert area. Small seeds have a long viability and can germinate after many years. Seeds svaynsony have a hard coating that protects the contents from the harsh arid environments until the next rain, but inhibits germination under normal household conditions.

For Svaynsony disastrous slightest damage to the roots, but when it grows in well-drained soils, it does not require frequent watering and can withstand not only extreme heat and sunlight, and even light frosts.

Sturt desert pea is not under threat of extinction, but yet to take out samples of plants from Australia without a special permit is illegal. Plants also can not collect on the territory of private land without the written consent of the owner of the land.

Formosa Clianthus was adopted as the emblem of South Australia 23 November 1961. This flower is often used as an element in the art of photography and decorative trim motif. Sturt Desert Peas are also often figugriruet in verse and prose, as well as some legends of Australia. Today, more often than the world can see Svaynsonu on stamps of Australia.
