Boronia crassifolia is a slender, rounded shrub that grows to a height of about 30 cm (10 in). It has pinnate leaves with three, five, or seven linear- to spatula-shaped leaflets 5–10 mm (0.2–0.4 in). The flowers are yellowish-green to brownish, about 10 mm (0.4 in) in diameter and hang from the leaf axils on a pedicel 3–5 mm (0.1–0.2 in) long. The four sepals are red, more or less round and about 2.5 mm (0.1 in) long. The four petals are about 4 mm (0.2 in) long. The eight stamens alternate in length, with the four near the petals longer than those near the sepals.[2][3][4][5]
