The aniseed boronia is a fennel-scented shrub that grows to 1 m tall (and rarely to 2 m tall). Its leaves are hairless, opposite and divided into 5-11 elliptic leaflets that grow to 8 mm long and 3 mm wide. The leaf margins are finely toothed. It flowers are white to deep pink, up to 15 mm wide and appear in the leaf axils (the upper angle between the leaf stalk and branch). Flowering occurs in spring. The aniseed boronia can be distinguished from the widespread, co-occurring Boronia muelleri by its smaller stature and its leaflets that are: shorter (less than 10 mm long), elliptic (compared to oblanceolate) and have toothed leaf margins (rather than smooth). Also, B. muelleri tends to prefer moister and more sheltered habitat.

Threats Table 1 threats impacting the aniseed boronia in approximate order of severity of risk; based on available evidence (Carter and Walsh; 2006) Threat factor Threat Threat Evidence base type status Fire Fire potential future Too frequent fire that doesn t allow plants to frequency sexually mature (and replenish the seed bank) may cause local extinction; however; there is no referenced study to confirm this or demonstrate the impact.
Fire intensity potential future Too intense fire may destroy seed; reducing regeneration success following fire; however; there is no referenced study to confirm this or demonstrate the impact.
