Hardenbergia perbrevidens

Hardenbergia perbrevidens is a slender, more or less glabrous twiner with trifoliate leaves on a petiole 15–35 mm (0.59–1.38 in) long, the leaflets narrowly egg-shaped to narrowly elliptic, 20–95 mm (0.79–3.74 in) long and 5–35 mm (0.20–1.38 in) wide. The flowers are arranged in racemes 30–200 mm (1.2–7.9 in) long with up to four flowers on a peduncle 8–5.5 mm (0.31–0.22 in) long, each on a pedicel 2–6 mm (0.079–0.236 in) long. The sepals are 3.5–4.0 mm (0.14–0.16 in) long and joined at the base, the upper two lobes fused and the lower three up to 0.6 mm (0.024 in) long. The petals are deep mauve to purple with yellow marks. Flowering occurs from June to September and the fruit is a pod 45–65 mm (1.8–2.6 in) long. This hardenbergia is similar to H. violacea, but that species has simple leaves.

Hardenbergia perbrevidens is found in inland north-eastern Queensland where it grows in sandy soil.
