Excoecaria parvifolia is a plant in the Euphorbiaceae family, native to Western Australia, the Northern Territory, and Queensland[1][2] It was first described by Johannes Müller Argoviensis in 1864, from a specimen collected by Ferdinand von Mueller in Arnhem Land.

[3][4] It is found across northern Australia, from northern Western Australia, the north of the Northern Territory, to northern Queensland,[2] growing on seasonally waterlogged clay flats, and occasionally on semi-saline soils.

[5] It flowers in the early wet season with fruits appearing from January to April.

[5] The Warumungu people of the Tennant Creek area know this tree as Manyingiila,[6] and use the smoke from burning the wood to keep away mosquitoes.

[6] Other Aboriginal language names are: Gurniny (Jaminjung, Ngaliwurru, Nungali), Yilili (MalakMalak, Matngala), Gilirr (Mangarrayi, Yangman).
