About Boronia rosmarinifolia A.Cunn. ex Endl.
Boronia rosmarinifolia A.Cunn. ex Endl. is an erect, many-branched woody shrub that reaches around 1 meter (3 feet) in height. It bears simple, linear to oblong leaves measuring 6 to 30 millimeters (0.2 to 1 inch) long and 1.5 to 3 millimeters (0.06 to 0.1 inch) wide, with edges that curve downward or roll under. Its flowers are most often pale to bright pink, rarely white, and are usually arranged individually in leaf axils on a stalk 2 to 7 millimeters (0.08 to 0.3 inch) long. This species has four hairy, egg-shaped to triangular sepals that are 2 to 4 millimeters (0.08 to 0.2 inch) long and 1.5 to 2.5 millimeters (0.06 to 0.1 inch) wide, and these sepals gradually grow larger as the fruit develops. It also has four petals that are 5 to 7.5 millimeters (0.2 to 0.3 inch) long and 3 to 4 millimeters (0.1 to 0.2 inch) wide, which also enlarge as the fruit develops. The eight stamens alternate in length, with the stamens near the sepals being longer than those near the petals. The style is hairless (glabrous). Flowering takes place from July to October. The fruit produced is a typically hairless capsule that measures 4 to 5.5 millimeters (0.16 to 0.22 inch) long and 2 to 2.5 millimeters (0.08 to 0.1 inch) wide. This species, commonly called forest boronia, grows in wallum heath and woodland, distributed between Bundaberg in Queensland and Grafton in New South Wales.
