About Boronia rhomboidea Hook.
Boronia rhomboidea Hook. is typically an erect, woody, many-branched shrub that grows up to 1 metre (3 feet) tall, though it is sometimes prostrate. Its younger branches are covered in soft hairs. The leaves are simple, broadly egg-shaped to nearly round, 5–15 millimetres (0.2–0.6 inches) long and wide, and often have a red tinge. Flowers are white to pale pink, arranged singly or in groups of up to three on branch ends or in leaf axils, and usually lack a peduncle. The four sepals are elliptic to oblong, 2.5–4.5 millimetres (0.1–0.2 inches) long and 1–2 millimetres (0.04–0.08 inches) wide, with a few short hairs. The four petals are 5–8 millimetres (0.2–0.3 inches) long, and the eight stamens are glabrous. The four-lobed stigma is slightly wider than the style. Flowering takes place from October to January, and the fruit is a glabrous capsule 3.5–4.5 millimetres (0.14–0.18 inches) long and about 2 millimetres (0.08 inches) wide. This species, commonly called broad-leaved boronia, grows in swampy heaths in New South Wales and Tasmania. In Tasmania it occurs in the highlands, and in New South Wales it grows on the Southern Tablelands, mainly in the Budawang Range.
