Description

Boronia pauciflora is an erect, many-branched shrub that grows to 60 cm (20 in) high and is only hairy when young. Its branches are more or less square in cross-section and the leaves are arranged in opposite pairs. Mature leaves are simple and have a petiole 0.5–7 mm (0.02–0.3 in) long, but juvenile leaves are trifoliate and sessile. Mature leaves and the end leaflet of juvenile leaves are elliptic to lance-shaped, 12–80 mm (0.5–3 in) long and 2–12 mm (0.08–0.5 in) wide and the side leaflets are a similar shape but shorter. The flowers are white to pink and are egg-shaped to triangular, usually arranged singly, sometimes in groups of up to three, in leaf axils on a pedicel 4–23 mm (0.2–0.9 in) long. The four sepals are egg-shaped to triangular, 2.5–4.5 mm (0.1–0.2 in) long and 1–2 mm (0.04–0.08 in) wide but almost double in size as the fruit develops. The petals are a similar size to the sepals and scarcely enlarge as the fruit develops. Flowering occurs from May to July. [2] [3] [4]

Taxonomy and naming

Boronia pauciflora was first formally described in 1918 by William Vincent Fitzgerald from a specimen he collected "above the base of Mt. Broome, King Leopold Ranges" (modern-day Wunaamin Miliwundi Ranges). The description was published in Journal and Proceedings of the Royal Society of Western Australia . [5] [6] The specific epithet (pauciflora) is derived from the Latin words paucus meaning "few" or "little" and -florus meaning "flowered". [7]

Distribution and habitat

This boronia grows in rocky places near the Prince Regent River, Edkins Range and King Leopold Ranges in the Kimberley region. [4] [8]

Conservation

Boronia pauciflora is classed as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife [8] meaning that it is poorly known and known from only a few locations but is not under imminent threat. [9]
