Wikipedia article of the day for September 1, 2015

The Wikipedia article of the day for September 1, 2015 is Acacia pycnantha.
Acacia pycnantha, commonly known as the golden wattle, is a tree of the family Fabaceae native to southeastern Australia. It grows to a height of 8 m (25 ft) and has sickle-shaped phyllodes (flattened leaf stalks) instead of true leaves. The profuse fragrant, golden flowers appear in late winter and spring, followed by long seed pods. Plants are cross-pollinated by several species of thornbill and honeyeater, which visit nectaries on the phyllodes and brush against flowers, transferring pollen between them. An understorey plant in eucalyptus forest, it is native to southern New South Wales, the Australian Capital Territory, Victoria, and southeastern South Australia. Explorer Thomas Mitchell collected the type specimen, from which George Bentham wrote the species description in 1842. Its bark produces more tannin than any other wattle species, resulting in its commercial cultivation for production of this compound. It has been widely grown as an ornamental garden plant and for cut flower production, but has become a weed in South Africa, Tanzania, Italy, Portugal, Sardinia, India, Indonesia, and New Zealand, as well as Western Australia, Tasmania and New South Wales. It was made the official floral emblem of Australia in 1988, and has been featured on the country's postal stamps.
