Fischer and Meyer (Compositae) isa perennial daisy with tufted leaves and long peduncles up to 30 cm, terminatingin white flowers. Flowering occurs between spring and early summer and flowersreadily set seed (Salkin et al., 1995). Brachyscome diversifolia occurs in openwoodland forest on steep rocky slopes and gullies, and on coastal cliffs (Salkin etal., 1995). There are two small extant populations of B. diversifolia in SouthAustralia, one at Scott Creek Conservation Park and the other at Ironbank, both inthe Adelaide Hills within 20 km of each other. Populations are restricted in SouthAustralia because of the species’ specialised habitat preferences. Potentialthreats to the species include grazing by slugs and snails (Salkin et al., 1995),weed invasion (Wilson &Bignall, 2009), tramplingof populations along hikingtrails, and limited suitablehabitat. The species isendangered in SouthAustralia (National Parksand Wildlife Act 1972). Italso occurs in New SouthWales, Victoria, andTasmania, but is not listedas threatened in thesestates.
