Boronia corynophylla is a plant in the citrus family, Rutaceae and is endemic to a small area in the south-west of Western Australia. It is a spreading shrub with thin, simple, cylindrical to narrow club-shaped leaves and pale red, four-petalled flowers in groups of up to three on the ends of the branches.

Description

[edit]

Boronia corynophylla is a spreading, densely branched shrub that grows to a height of about 30 cm (10 in) with its branches covered with soft hairs. It has simple, thin cylindrical to narrow spindle-shaped or club-shaped leaves 7–10 mm (0.3–0.4 in) long and about 1 mm (0.04 in) wide. The flowers are pale red and are borne singly or in groups of up to three on the end of the stems, each on a pedicel 1–2 mm (0.04–0.08 in) long with two tiny bracteoles at the base. The four sepals are egg-shaped, dark reddish brown, 2.5–3 mm (0.098–0.12 in) long and hairy with many pimply glands. The four petals are egg-shaped and leathery, about 5 mm (0.2 in) long with their bases overlapping. The eight stamens are club-shaped with those nearest the sepals slightly longer than those near the petals.[2][3]

Taxonomy and naming

[edit]

Boronia corynophylla was first formally described in 1998 by Paul G. Wilson and the description was published in Nuytsia from a specimen collected in the Frank Hann National Park.[4][2] The specific epithet (corynophylla) is derived from the Ancient Greek words koryne meaning "club" or "mace"[5]: 213  and phyllon meaning "leaf",[5]: 466  referring to the club-shaped leaves.[2]

Distribution and habitat

[edit]

This boronia grows is only known from the Frank Hann National Park where it grows in Eucalyptus salmonophloia woodland.[2][3]

Conservation

[edit]

Boronia corynophylla is classified as "Priority Two" by the Government of Western Australia Department of Parks and Wildlife[3] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[6]
