Aerva javanica, the kapok bush or desert cotton, is a species of plant in the family Amaranthaceae.
It has a native distribution incorporating much of Africa (including Madagascar), and the south-west and south of Asia, and it has become adventitious in northern Australia.
[2][3] The plant is herbaceous, multi-stemmed and soft-wooded and bears broad leaves; it often has an erect habit and grows to a height of about 1.6 metres (5 ft 3 in).
[4] Diplospory, a type of Agamospermy, occurs during the development of female gametophyte in the ovule and hence reduction division does not take place in the Megaspore mother cell.
[8] The plant has naturalised in northern regions of Australia, as an alien introduction, and is cultivated and utilised by the indigenous peoples of some countries.
