The plant has four to ten leaves, with scattered black spines up to 4 centimetres (1.6 in) long. The leaves have nine to thirteen light green pinnae on each side, which are arranged in clusters of two or three. The leaf stems are 0.6–1 metre (2.0–3.3 ft) long.[3]
The inflorescence stem is curved, up to 10 centimetres (3.9 in) long, and densely covered in spines. The female flowers are up to 4 millimetres (0.16 in) long. The calyx is cup-shaped, and around 1 millimetre (0.039 in) long. The corolla is around 3 millimetres (0.12 in) long, and tube-shaped. Both the calyx and corolla have brown spines, which are bent alternately in different directions.[3]
