Boronia odorata explained

Boronia odorata is a plant in the citrus family Rutaceae and is endemic to the central highlands of Queensland, Australia. It is an erect shrub with many branches, mostly simple leaves and pink to white, four-petalled flowers.

Description

Boronia odorata is an erect, many-branched shrub which grows to a height of 2sigfig=1NaNsigfig=1 with its young branches densely covered with white to reddish brown hairs. Mature plants have simple leaves but the leaves of young plants are trifoliate. Mature leaves and the young leaflets are elliptic in shape, NaNsigfig=1NaNsigfig=1 long and NaNsigfig=1NaNsigfig=1 wide and the side leaflets are shorter and narrower. The leaves have a winged petiole NaNsigfig=1NaNsigfig=1 long. Up to three pink to white flowers are arranged in leaf axils on a hairy stalk NaNsigfig=2NaNsigfig=2 long. The four sepals are egg-shaped to triangular, NaNsigfig=2NaNsigfig=2 long, NaNsigfig=2NaNsigfig=2 wide and hairy. The four petals are NaNsigfig=2NaNsigfig=2 long, NaNsigfig=2NaNsigfig=2 wide and enlarge as the fruit develops. The eight stamens alternate in length, size and shape. Flowering occurs from February to October and the fruit are NaNsigfig=2NaNsigfig=2 long and NaNsigfig=2NaNsigfig=2 wide.[1]

Taxonomy and naming

Boronia odorata was first formally described in 1999 by Marco F. Duretto and the description was published in the journal Austrobaileya.[2] The specific epithet (odorata) is a Latin word meaning "having a smell" or "fragrant"[3] referring to the tar or coffee odour of the leaves when crushed.

Distribution and habitat

This boronia grows in woodland on sandstone in the central highlands of Queensland in an area bounded by Springsure, Theodore, Surat, Mitchell and Tambo.

Conservation

Boronia odorata is classed as "least concern" under the Queensland Government Nature Conservation Act 1992.[4]
