The leaves are needle-shaped, 7–12 mm (0.28–0.47 in) long and 0.8–1.4 mm (0.031–0.055 in) wide and hairy with stipules at the base. The flowers are yellow and red with red and yellow markings. Each flower is borne on a pedicel 0.6–2.5 mm (0.024–0.098 in) long with hairy bracteoles 1.5–2.5 mm (0.059–0.098 in) long at the base. The sepals are 5–6 mm (0.20–0.24 in) long and hairy. The standard petal is 6.5–10.4 mm (0.26–0.41 in) long and glabrous, the wings are 6–8.5 mm (0.24–0.33 in) long and the keel 6.8–8.2 mm (0.27–0.32 in) long. Flowering occurs in March and October and the fruit is an oval pod.[2]
