Boronia amabilis, commonly known as Wyberba boronia, is a plant in the citrus family, Rutaceae and is endemic to a small area in southern Queensland. It is an erect shrub with many branches, pinnate leaves with hairy lower surfaces and pink, four-petalled flowers.
Boronia amabilis is an erect shrub that grows to a height of 3sigfig=1NaNsigfig=1 with many branches covered with dense white to reddish brown, star-shaped hairs but which become glabrous with age. The leaves are NaNsigfig=2NaNsigfig=2 long and NaNsigfig=2NaNsigfig=2 wide in outline, and pinnate. They have between three and fifteen elliptic leaflets that are hairy on the lower side. The end leaflet is NaNsigfig=1NaNsigfig=1 long and NaNsigfig=1NaNsigfig=1 wide, the others slightly smaller. The flowers are pink and are arranged in leaf axils, mainly in groups of between three and seven. The groups are borne on a peduncle NaNsigfig=1NaNsigfig=1 long. The four sepals are narrow egg-shaped to triangular, NaNsigfig=1NaNsigfig=1 long and NaNsigfig=1NaNsigfig=1 wide. The four petals are mostly NaNsigfig=1NaNsigfig=1 long and NaNsigfig=1NaNsigfig=1 wide and hairy on the lower surface. The eight stamens alternate in length, the slightly shorter ones opposite the petals. The fruits are glabrous, NaNsigfig=2NaNsigfig=2 long and NaNsigfig=2NaNsigfig=2 wide.[1]
Boronia amabilis was first formally described in 1963 by Stanley Thatcher Blake and the description was published in Proceedings of the Royal Society of Queensland.[2] The specific epithet (amabilis) is a Latin word meaning "lovely".[3]
This boronia grows in forest and woodland over granite between Wyberba and nearby Girraween National Park in south-eastern Queensland.
Boronia amabilis is classified as "near threatened" under the Queensland Government Nature Conservation Act 1992.[4]
