MuM, GipP. NSW. Very rare, confined in Victoria to swampy land and lake margins in the Rosedale-Stradbroke-Providence Ponds area, with an isolated occurrence on the Genoa River near Wangarabell following the 2019 fires.
Plants seem to persist for a few (up to about 10) years post-disturbance before senescing. Germination of soil-stored seeds usually follows flood, fire or earthworks.
