About Boronia granitica Maiden & Betche
Boronia granitica, also known as granite boronia, is an erect, many-branched shrub that reaches a height of up to 1.5 meters (5 feet). Its branches and leaves are covered in white to reddish-brown star-shaped hairs. Its leaves are compound, with between seven and fifteen leaflets per leaf. The full leaf outline measures 8–20 mm (0.31–0.79 in) in length and 2.5–15 mm (0.098–0.59 in) in width. The terminal end leaflet is 1–11 mm (0.039–0.43 in) long and 0.5–2.5 mm (0.020–0.098 in) wide, while the side leaflets are 1–6 mm (0.039–0.24 in) long and 0.5–2 mm (0.020–0.079 in) wide. This species produces pink flowers, which are arranged singly or in groups of three in leaf axils, on a stalk 1–3 mm (0.039–0.12 in) long. It has four triangular to narrow egg-shaped sepals that are 3.5–5 mm (0.1–0.2 in) long, and these enlarge as the fruit develops. The four petals are 6–9 mm (0.2–0.4 in) long and 3–4 mm (0.1–0.2 in) wide, and they also enlarge as fruit develops. There are eight stamens that alternate in length, with the stamens opposite the sepals being slightly longer. Flowering takes place from July to December. The fruit produced is 4.5–7 mm (0.18–0.28 in) long and 2.5–3 mm (0.098–0.12 in) wide. This plant grows in open forest, woodland, and heath on granite soils. Its natural range lies between Stanthorpe in Queensland and Armidale in New South Wales.
