Description
Boronia hapalophylla is an erect or straggling shrub that grows to about 3 m (10 ft) high and has branches with minute, star-like hairs. The leaves are simple, narrow elliptic to lance-shaped, mostly 18–50 mm (0.7–2 in) long, 3.5–12 mm (0.1–0.5 in) wide with a hairy, paler underside and the edges rolled down. The leaves are sessile or sometimes have a petiole up to 1.5 mm (0.06 in) long. The flowers are pink, sometimes white and are arranged singly or in groups of up to seven in leaf axils, the groups on a peduncle up to 5 mm (0.2 in) long (if present), the individual flowers on a pedicel 2–6.5 mm (0.08–0.3 in) long. The four sepals are broadly egg-shaped to triangular, mostly 5–10 mm (0.2–0.4 in) long, 3–4.5 mm (0.1–0.2 in) wide and hairy on the back. The four petals are 6–15 mm (0.2–0.6 in) long and densely hairy on the back. Flowering occurs mainly in August and September.[2][3][4][5]
Boronia hapalophylla is listed as "endangered" under the New South Wales Government Biodiversity Conservation Act 2016. The main threats to the species include habitat disturbance, weed invasion and trampling by domestic stock and feral herbivores.[5]
