About Jacksonia furcellata (Bonpl.) DC.
Jacksonia furcellata is a shrub that can be prostrate, low-lying, weeping, or erect, with sharply-pointed side branches. It typically grows to a height of 0.4–6 m (1 ft 4 in – 19 ft 8 in) and a width of 1–3 m (3 ft 3 in – 9 ft 10 in). The shrub has greyish-green branches; its short end branches measure 2–15.8 mm (0.079–0.622 in) long, about 1.5 mm (0.059 in) wide, and are sharply-pointed. Its leaves are reduced to broadly egg-shaped scales with toothed edges, 1.2–3.9 mm (0.047–0.154 in) long and 0.6–1.8 mm (0.024–0.071 in) wide. Flowers are arranged at the ends of branches in raceme-like groups, growing from a pedicel that is 2.3–4.7 mm (0.091–0.185 in) long. Egg-shaped bracteoles 1.3–1.7 mm (0.051–0.067 in) long are located on the upper section of each pedicel. The floral tube measures 1.0–1.4 mm (0.039–0.055 in) long. The sepals are membranous, 7.5–12.3 mm (0.30–0.48 in) long and 1.6–2.4 mm (0.063–0.094 in) wide. The standard petal is yellowish-orange with red markings, 6.5–8.8 mm (0.26–0.35 in) long. The wing petals are the same colour and 6.1–7.9 mm (0.24–0.31 in) long. The keel is orange-red, 6.6–8.9 mm (0.26–0.35 in) long. The stamens have red filaments 5.2–11.9 mm (0.20–0.47 in) long. This species flowers year-round, with a peak flowering period from October to December or January to March. Its fruit is a woody, hairy pod 7–8 mm (0.28–0.31 in) long and 3.5–4.0 mm (0.14–0.16 in) wide. Jacksonia furcellata grows in heath or woodland, often in winter-wet areas. It is widespread across south-western Western Australia between Dandaragan, the south-west corner of the state, and eastward to the Lort River. It is absent from coastal areas between Augusta and Denmark, and occurs in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Mallee, Swan Coastal Plain and Warren regions of south-western Western Australia.
