Boronia anceps

Boronia anceps is a perennial herb that grows to a height of 60 cm (20 in), has flattened stems and lacks a lignotuber. Its leaves are narrow egg-shaped to narrow oblong about 20 mm (0.8 in) long although those near the top are very reduced. The flowers are pink or pinkish purple and are borne in a cyme on the tip of the stems. The groups of flowers are on a thin peduncle up to 60 mm (2 in) long, each flower on a thin pedicel 5–10 mm (0.2–0.4 in) long. The four sepals are dark red, narrow triangular to broadly egg-shaped and 2–4 mm (0.08–0.2 in) long. The four petals are broadly egg-shaped and about 8 mm (0.3 in) long with their bases overlapping. The style and stigma are continuous. Flowering occurs from September to December or January.[2][3]

Boronia anceps was first formally described in 1998 by Paul G. Wilson and the description was published in Nuytsia from a specimen collected near a crossing on the Scott River near Augusta.[4][2] The specific epithet (anceps) is a Latin word meaning "two-sided",[5] referring to the shape of the stem.[2]

This boronia grows in seasonally swampy heath and is only known from between the Scott River and Walpole.[2][3]

Boronia anceps 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]
