Jacksonia velutina

Jacksonia velutina is an erect, broom-like, coarse shrub that typically grows up to 0.5–2.6 m (1 ft 8 in – 8 ft 6 in) high and 0.9–2 m (2 ft 11 in – 6 ft 7 in) wide. It has greyish-green branches, the end branches sharply-pointed cladodes, its leaves reduced to egg-shaped, dark brown scales, 1–3 mm (0.039–0.118 in) long and 1.3–3 mm (0.051–0.118 in) wide. The flowers are in clusters along the branches on curved pedicels 1.6–2.4 mm (0.063–0.094 in) long, with thread-like bracteoles 1.9–3.3 mm (0.075–0.130 in) long, 0.35–0.6 mm (0.014–0.024 in) wide on the base of the floral tube, but that fall off as the flowers mature. The floral tube is 1.2–1.35 mm (0.047–0.053 in) long and not ribbed, and the sepals are membranous, with lobes 6.9–10 mm (0.27–0.39 in) long, 1.8–2.6 mm (0.071–0.102 in) wide and fused for 1.0–1.3 mm (0.039–0.051 in). The standard petal is yellow-orange with red markings only on the inner surface, 7.2–8.7 mm (0.28–0.34 in) long and 12.1–13 mm (0.48–0.51 in) deep, the wings yellow-orange with red markings, 5.4–6.2 mm (0.21–0.24 in) long, and the keel is dark red, 7.5–8.7 mm (0.30–0.34 in) long. The stamens have yellow filaments with a red tip, 4.5–8.7 mm (0.18–0.34 in) long. Flowering occurs from July to November, and the fruit is a membranous, flattened elliptic, densely hairy pod 6.3–8.0 mm (0.25–0.31 in) long and 2.4–2.5 mm (0.094–0.098 in) wide.

This species of Jacksonia grows in yellow sand over laterite or limestone in shrubland and is found from the Billabong Roadhouse south of Shark Bay to Watheroo in the Avon Wheatbelt, Geraldton Sandplains and Yalgoo bioregions of Western Australia.
