Boronia juncea is a plant in the citrus family, Rutaceae and is endemic to the far south-west of Western Australia. It is an erect shrub with linear, short-lived leaves and groups of up to eight white to pink, four-petalled flowers.
Boronia juncea is an erect shrub that grows to a height of 20–80 cm (8–30 in) with short-lived leaves. The lower leaves are linear, 20–40 mm (0.79–1.6 in) long and the upper leaves are more or less cylindrical and 10–40 mm (0.39–1.6 in) long. Between three and eight pink to white flowers are arranged in groups, each flower on a thin pedicel 10–50 mm (0.39–2.0 in) long. The four sepals are dark red, triangular to narrow egg-shaped and 1.5–5 mm (0.059–0.20 in) long. The four petals are mostly 3–8 mm (0.1–0.3 in) long. The eight stamens are hairless. Flowering occurs from October to December or from January to April.[2][3]
Taxonomy and naming
Boronia juncea was first formally described in 1845 by Friedrich Gottlieb Bartling and the description was published in Plantae Preissianae.[4][5] The specific epithet (juncea) is a Latin word meaning "of rushes".[6]
There are four subspecies intergrading with each other:
- Boronia juncea subsp. juncea[7] has hairless pedicels and sepals;[8]
- Boronia juncea subsp. laniflora[9] has woolly sepals and petals, the sepals 1.5–3 mm (0.059–0.12 in) long;[8]
- Boronia juncea subsp. micrantha[10] has woolly sepals and petals, the sepals 3–5 mm (0.12–0.20 in) long with a sharply pointed tip;[8]
- Boronia juncea subsp. minima[11] has woolly sepals and petals, the sepals 3–5 mm (0.12–0.20 in) long with a tapered tip.[8]
