Hyperbaena ilicifolia is a shrub or tree that grows up to 10 metres (33 ft) high. The trunk is up to 15 centimetres (5.9 in) wide. The branches are subcylindrical and greyish.[3]
The leaves are stiff, leathery, ovate, 1.7–20 centimetres (0.67–7.87 in) long, 1.2–16.5 centimetres (0.47–6.50 in) wide, and have spiny or toothed edges. The stem is 0.5–4 centimetres (0.20–1.57 in) long.[3]
The male inflorescence is a spike or raceme, and usually clustered. It grows on a stem that is up to 1 centimetre (0.39 in) long. The flower stems are up to 1 millimetre (0.039 in) long. The male flowers are greenish-white or yellow, and have six sepals. The outer sepals are obovate-elliptic, around 2 millimetres (0.079 in) long, and around 0.8 millimetres (0.031 in) wide. The inner sepals are broadly obovate, around 2 millimetres (0.079 in) long, and around 1.3 millimetres (0.051 in) wide.

The female flowers are greenish-white or yellow, and have six sepals. The outer sepals are oblong, around 1.8 millimetres (0.071 in) long, and around 0.9 millimetres (0.035 in) wide. The inner sepals are ovate-orbicular, around 2.2 millimetres (0.087 in) long, and around 1 millimetre (0.039 in) wide. The female flowers have six petals, which are oblong, around 0.5 millimetres (0.020 in) long, and around 0.2 millimetres (0.0079 in) wide.The female flowers have three or four carpels.[3]
