Distribution & Habitat
New South Wales, Australia
"A forest shrub from a restricted area that is now within the urbanised area of northern Sydney, Australia. The principal threat is habitat destruction during the expansion of suburban Sydney, which began slowly in the early 19th century and accelerated during the 20th century. Although the rate of habitat destruction had slowed by the late 20th century, the remnants continue to be degraded by eutrophication and alien plant invasions. This makes the habitat unsuitable for persistence of many native plant taxa."
