Lysimachia nummularia (Primulaceae) naturalised in New South Wales, Australia

Abstract

In November 2015 the first naturalised collection of Lysimachia nummularia L. (Primulaceae) was made for New South Wales from the Apsley River on the Northern Tablelands. This creeping, perennial herb is native to Eurasia and previously recorded as naturalised in Australia in Victoria and Tasmania. It has the potential to be an invasive weed, particularly in wetland and other damp habitats. A description of L. nummularia is provided as well as a key to Lysimachia taxa occurring in New South Wales.
