Habitat details as listed in assessment
This small shrub species typically grows in sand sheets and is able to inhabit saline sand and disturbed areas along the coast (Western 1992, Böer and Saenger 2006, Norton et al. 2009, MEW 2010). As such, it is considered to be a halophyte, or salt-tolerant, species (Sakkir et al. 2017). It is considered to be a characteristic species of its preferred environment (Böer and Saenger 2006). The species can grow up to 0.8 m in height and its leaves vary from linear and hairy to small and round, depending on the season (Jongbloed et al. 2003). It also has winged fruit and produces yellow flowers between September and December (Jongbloed et al. 2003). When crushed, the leaves of this plant produce an unpleasant smell (Jongbloed et al. 2003).
