Boronia floribunda, commonly known as pale pink boronia, is a plant in the citrus family, Rutaceae and is endemic to near-coastal areas of eastern New South Wales. It is an erect, woody shrub with compound leaves and large numbers of white to pale pink, four-petalled flowers in spring and early summer.
Boronia floribunda is an erect, woody shrub that grows to a height of NaNsigfig=1NaNsigfig=1. The leaves have five, seven or nine narrow elliptic leaflets with the end leaflet the shortest. The leaflets are NaNsigfig=2NaNsigfig=2 long and NaNsigfig=2NaNsigfig=2 wide. The leaf is NaNsigfig=2NaNsigfig=2 long and NaNsigfig=2NaNsigfig=2 wide in outline with a petiole NaNsigfig=2NaNsigfig=2 long. The flowers are usually white to pale pink, sometimes deep pink and are arranged in leaf axils, in groups of up to nine. The four sepals are triangular, about NaNsigfig=2NaNsigfig=2 long and NaNsigfig=2NaNsigfig=2 wide. The four petals are NaNsigfig=1NaNsigfig=1 long. The eight stamens have hairy tips so that the hairs form a raised ring when viewed from above. The stigma is distinctly swollen. Flowering mainly occurs from September to January and the fruit are glabrous, NaNsigfig=2NaNsigfig=2 long and NaNsigfig=2NaNsigfig=2 wide.[1] [2]
Boronia floribunda was first formally described in 1825 by Heinrich Gustav Reichenbach from an unpublished manuscript by Franz Sieber and the description was published in Iconographia Botanica Exotica.[3] [4] The specific epithet (floribunda) a Latin word meaning "abounding in flowers" or "flowering profusely",[5] presumably alluding to a feature of this species.
This boronia grows in heath and forest on sandstone in the Sydney region, including in Garigal, Ku-ring-gai Chase, Blue Mountains and Nattai National Parks.
