PENNY WART

Pennywort (Centella asiatica) a long-lived herbaceous plant with creeping stems that regularly produce roots at the joints. Its leaves are arranged in clusters along the stems and are borne on stalks 0.5-15 cm long. These leaves (1-4.5 cm long and 1.5-5 cm wide) are kidney-shaped and usually have bluntly toothed margins. Its inconspicuous pink or purplish flowers are arranged in small clusters. Its small fruit (2.2-5 mm wide) are ribbed and split into two one-seeded segments when mature.

Centella asiatica quickly exploits localised soil disturbance to establish in riparian zones.

This species is widespread in the tropical, sub-tropical and warm-temperate regions of the world (i.e. it is almost cosmopolitan). Its exact origin is obscure, but it is thought to be native to the Indian sub-continent, south-eastern Asia and Australia. It is native to the coastal and sub-coastal districts of southern, eastern and northern Australia (i.e. south-western Western Australia, south-eastern South Australia, Victoria, eastern New South Wales, eastern Queensland, and the northern parts of the Northern Territory.Naturalised on Lord Howe Island and Norfolk Island.
