Acetosa vesicaria

Acetosa vesicaria (syn. Rumex vesicaria L.) native to western Asia and North Africa is naturalised in inland parts of all other mainland States and is well known for its bright pink or purplish, bladder-like fruiting perianths (to c. 25 mm long) producing massed displays in areas such as the Flinders Ranges in South Australia, Broken Hill in New South Wales and Central Australia. It has been recorded sporadically in far north-west and western Victoria as a result of supposed deliberate plantings, or possibly dispersed by trains, but has not been demonstrated to persist in this State. Unlike A. sagittata, it is an erect, rather succulent annual to c. 60 cm high, with triangular to ovate leaves that are truncate or cordate at the base and c. 5–10 cm long.
