About Boronia rivularis C.T.White
Boronia rivularis is an erect, woody shrub that typically grows to about 2.0 metres (7 feet) tall, and has smooth young branches. Its leaves are pinnate, with between three and thirteen leaflets per leaf. The overall leaf outline measures 17–68 mm (0.67–2.7 inches) long and 15–64 mm (0.59–2.5 inches) wide, with a petiole 5–15 mm (0.20–0.59 inches) long. The end leaflet is elliptic, 4–32 mm (0.16–1.3 inches) long and 1–5 mm (0.039–0.20 inches) wide, and the side leaflets are similar in size and shape. Groups of three to nine white to pink flowers grow in leaf axils or on the ends of branches, attached to a thin stalk 5–17 mm (0.20–0.67 inches) long. The four sepals are roughly triangular, and are less than 1 mm (0.039 inches) long and wide. The four petals measure 5–8 mm (0.20–0.31 inches) long. The eight stamens have hairy edges. Flowering takes place from September to December. The fruit of this species is 3–4.5 mm (0.12–0.18 inches) long and 2–2.5 mm (0.079–0.098 inches) wide. This species, commonly called Wide Bay boronia, grows in moist, swampy areas within heath, woodland, or open forest. It occurs on Fraser Island and in the Cooloola area.
