About Boronia amabilis S.T.Blake
Boronia amabilis is an erect, many-branched shrub that grows up to 3 m (10 ft) tall. Its branches are covered in dense white to reddish-brown star-shaped hairs, and become hairless (glabrous) as they age. The leaves are pinnate, 10β55 mm (0.39β2.2 in) long and 6β28 mm (0.24β1.1 in) wide in outline, with between three and fifteen elliptic leaflets. Leaflets are hairy on their lower surface; the end leaflet measures 3β18 mm (0.1β0.7 in) long and 1.5β6 mm (0.06β0.2 in) wide, and the other leaflets are slightly smaller. Pink flowers of this species are arranged in groups of three to seven in leaf axils, and the groups grow from a peduncle 2β5 mm (0.08β0.2 in) long. It has four narrow egg-shaped to triangular sepals that are 3.5β6 mm (0.1β0.2 in) long and 1β2.5 mm (0.04β0.1 in) wide. The four petals are mostly 8β12 mm (0.3β0.5 in) long and 4β6 mm (0.2β0.2 in) wide, and are hairy on the lower surface. There are eight stamens that alternate in length, with the slightly shorter stamens positioned opposite the petals. The hairless fruits of Boronia amabilis are 4β5 mm (0.16β0.20 in) long and 2β3 mm (0.079β0.12 in) wide. This boronia grows in forest and woodland growing over granite, occurring between Wyberba and nearby Girraween National Park in south-eastern Queensland.
