*CVU, *EGL, *EGU, *GipP, *Glep, *LoM, *MuM, *NIS, *RobP, *Wim. Also naturalised SA, Qld, NSW, Tas. (King Is. and Flinders Is.). Native to southern Africa. Chiefly in the north-west (e.g. Hattah Lakes, Lake Albacutya, Wyperfeld National Park etc.) and rain-shadow areas of East Gippsland (Suggan Buggan, Willis), with a few scattered occurrences in the south. Occurs in open areas and woodlands along roads, streams, and shores, usually in sand or sandy loam.
Considering morphological, cytological, and phytogeographic evidence, Kadereit (1988) concluded that Papaver aculeatum probably is not native in Australia, but was introduced from southern Africa soon after white settlement.
