Ricinocarpos stylosus is a spreading, rounded, monoecious or dioecious shrub that typically grows to height of up to 2 m (6 ft 7 in), sometimes a small tree up to 5 m (16 ft) high, its young branchlets sticky. The leaves are linear to narrowly oblong, 6–10 mm (0.24–0.39 in) long and 1.0–1.5 mm (0.039–0.059 in) wide on a petiole 1–2 mm (0.039–0.079 in) long. The upper surface of the leaves is more or less glabrous and the lower surface is covered with soft, white, star-shaped hairs. The flowers are arranged on the ends of branchlets with a single female, or with two to five male flowers, or a single female flower surrounded by up to four male flowers. Each flower has 5 sepals joined at the base but there are no petals. Male flowers are on a slender pedicel 3–5 mm (0.12–0.20 in) long, the sepal lobes 3–4 mm (0.12–0.16 in) long and 1.5–3.0 mm (0.059–0.118 in) wide. There are about 35 stamens in a central column 2–3 mm (0.079–0.118 in) long. Female flowers are on a stout pedicel 3–6 mm (0.12–0.24 in) long, the sepal lobes 3–4 mm (0.12–0.16 in) long and 1.5–3 mm (0.059–0.118 in) wide. Flowering occurs between August to January, and the fruit is more or less spherical capsule 7.0–10 mm (0.28–0.39 in) in diameter. [2] [3]
