Abstract
Neurada procumbens L. (Neuradaceae) is a species from arid regions of north Africa, the Middle East and north west India and is here reported for the first time as a naturalized weed in arid Australia. This distinctive species is apparently confined to a small area on the north western edge of the Simpson Desert. There is presently a very real chance of eradicating the species because the population is relatively small and readily accessible. However, eradication may be only a fleeting option as the species has a spiny fruit that is readily dispersed by animals, humans and vehicles, and it appears to be capable of reproducing in highly arid sandy situations, of which there are vast tracts of suitable habitat in arid Australia.
