Ricinocarpos muricatus is an erect to spreading, sticky, monoecious shrub that typically grows to height of up to 2.5 m (8 ft 2 in), its young branchlets soon glabrous. The leaves are linear, mostly 20–45 mm (0.79–1.77 in) long and 1–2 mm (0.039–0.079 in) wide on a glabrous petiole up to 1 mm (0.039 in) long. The upper surface of the leaves is glabrous and the lower surface is covered with soft, star-shaped hairs. The flowers are yellow and arranged in racemes with one or two female flowers on the ends of branches, with 8 to 12 male flowers below them. Male flowers are on a slender pedicel 1–3 mm (0.039–0.118 in) long, the sepals joined at the base, the sepal lobes 2.3–3.0 mm (0.091–0.118 in) long with 5 fleshy glands. There are 20 to 30 stamens in a central column 2–3 mm (0.079–0.118 in) long. Female flowers are on a pedicel 6–12 mm (0.24–0.47 in) long, the sepal lobes 2.0–4.4 mm (0.079–0.173 in) long and 0.9–5 mm (0.035–0.197 in) wide. Flowering has been observed from April to November, and the fruit is a more or less spherical or oval capsule 5–7 mm (0.20–0.28 in) long and wide. [2] [3]
