Royce’s Waxflower forms an intricately branched spreading shrub up to 120 cm tall and 60 cm across. It has inconspicuous greenish-white flowers and young branches are coloured fawn to reddish (Brown et al. 1998; Smith 1994). This species occurs on the Southern Swan Coastal Plain below the Whicher Range, near Busselton, Western Australia (Brown et al. 1998). There are a number of populations, many in close proximity, scattered between Capel, Busselton, Tutunup and Ambergate (Williams et al. 2001). Royce’s Waxflower is confined mainly to remnant heathland along the abandoned Nannup-Busselton Railway (in the Tutunup-Ruabon area). A small population also occurs along a narrow road verge about 15 km south-west of the main population, near the Vasse River (Lindburg Road population). Royce’s Waxflower is mainly found on land vested for the purposes of a railway, with much smaller areas on road reserves, a drainage reserve and in a nature reserve (Smith 1994).
