Boronia mollis

Boronia mollis, commonly known as the Soft Boronia, is a plant in the citrus family occurring in eastern Australia. Seen between a half of a metre to two metres tall, it is found in moist gullies usually on sandstone based soils. The leaves have an unpleasant citrus/bitumen type scent. Typical Boronia looking flowers form in spring from cymes in the leaf axils. The specific epithet mollis refers to the soft hairs and soft leaves. The original specimen was collected by the Nepean River in 1825, and officially described in 1841.
