Abstract

The natural distribution of the native species Acacia trigonophylla Meisn. is from the Geraldton Sandplains through to the Avon Wheatbelt and the Mallee Bio-Regions and probably also the eastern Jarrah Forest Bio-Region of Western Australia. However, extensive road side and revegetation plantings, combined with poorly documented collections of these non-native plantings, has given this species an apparently much wider range to the west of its native habitats. The species is beginning to invade wetlands and banksia woodland on the Swan Coastal Plain from these plantings. This species illustrates the need by both curators and researchers to carefully review general herbarium collections before (and after) they are added to databases and several suggestions to undertake this are given. In the case of Acacia trigonophylla a search would give the native range in five rather than three bio-regions. This has major implications for planning of restoration projects since this species has the potential to become a weed in natural habitats outside its natural range.
