Its leaves are reduced to narrowly lance-shaped, dark brown scales, 0.8–2 mm (0.031–0.079 in) long and 0.6–0.9 mm (0.024–0.035 in) wide. The flowers are arranged at the ends of branches in raceme-like clusters on a pedicel 1.3–1.6 mm (0.051–0.063 in) long, with narrowly lance-shaped bracteoles 0.5–1.5 mm (0.020–0.059 in) long and 0.4–0.5 mm (0.016–0.020 in) wide near the top of the pedicels. The floral tube is 0.3–0.6 mm (0.012–0.024 in) long and the sepals are membranous, with lobes 3.0–5.7 mm (0.12–0.22 in) long and 0.8–2.0 mm (0.031–0.079 in) wide. The standard petal is yellow-orange with a red "eye", 3.2–4.7 mm (0.13–0.19 in) long, the wings yellow-orange with a red base, 3.3–4.2 mm (0.13–0.17 in) long, and the keel is yellow-orange or red, 2.1–3.6 mm (0.083–0.142 in) long. The stamens have white filaments with pink ends and are 1.3–3.5 mm (0.051–0.138 in) long. Flowering occurs from July to December, and the fruit is a woody, densely hairy pod 3.5–3.7 mm (0.14–0.15 in) long and 2.5–3.3 mm (0.098–0.130 in) wide. [2] [3]
Jacksonia alata was first formally described in 1837 by George Bentham in Stephan Endlicher's Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel . [4] [5] from specimens collected near King George Sound. The specific epithet (alata) means 'winged', referring to the stems. [6]
