위키 설명

 

Acacia dealbata, the silver wattle, blue wattle[3] or mimosa,[4] is a species of flowering plant in the legume family Fabaceae, native to southeastern Australia in New South Wales, Victoria, Tasmania, and the Australian Capital Territory, and widely introduced in Mediterranean, warm temperate, and highland tropical landscapes.[5][6]

Description

It is a fast-growing evergreen tree or shrub growing up to 30 m tall, typically a pioneer species after fire. The leaves are bipinnate, glaucous blue-green to silvery grey, 1–12 cm (occasionally to 17 cm) long and 1–11 cm broad, with 6–30 pairs of pinnae, each pinna divided into 10–68 pairs of leaflets; the leaflets are 0.7–6 mm long and 0.4–1 mm broad. The flowers are produced in large racemose inflorescences made up of numerous smaller globose bright yellow flowerheads of 13–42 individual flowers. The fruit is a flattened pod 2–11.5 cm long and 6–14 mm broad, containing several seeds.[3][7] Trees generally do not live longer than 30 to 40 years, after which in the wild they are succeeded by other species where bushfires are excluded. In moist mountain areas, a white lichen can almost cover the bark, which may contribute to the descriptor "silver".[citation needed] The Latin specific epithet dealbata also means "covered in a white powder".[8] The Wiradjuri people of New South Wales use the name Giigandul for the species.[9]

Taxonomy

Along with other bipinnate wattles, Acacia dealbata is classified in the section Botrycephalae within the subgenus Phyllodineae in the genus Acacia. An analysis of genomic and chloroplast DNA along with morphological characters found that the section is polyphyletic, though the close relationships of many species were unable to be resolved. Acacia dealbata appears to be most closely related to A. mearnsii, A. nanodealbata and A. baileyana.[12]

Some authorities consider A. dealbata to be a variant of Acacia decurrens.[3]

Subspecies

There are two subspecies:[5]

A. dealbata subsp. dealbata. Low to moderate altitudes. Tree to 30 m; leaves mostly 5–12 cm long.

A. dealbata subsp. subalpina Tindale & Kodela. High altitudes in the Snowy Mountains. Shrub to 5 m (rarely 10 m) tall; leaves mostly 1.5–8.5 cm long.

 

Cultivation(생략)

Mimosa

The flowers and tip shoots are harvested for use as cut flowers, when it is known by the florist trade as "mimosa" (not to be confused with the genus of plants called Mimosa). In Italy,[20] Albania, Russia and Georgia the flowers are also frequently given to women on International Women's Day.[citation needed] The essence of the flowers, called 'mimosa', or in older texts, 'cassie', is used in perfumes.[21]
