Apowollastonia stirlingii is a small herb or understory shrub up to 80 cm (31 in) high, 2 m (6 ft 7 in) in diameter and upright stems with more or less corky bark. The green branches rough with hard protrusions, ridged and lower parts woody. The leaves are arranged in sparse pairs, sessile,linear or linear-lance shaped, gradually narrowing at the base, 2–5 cm (0.79–1.97 in) long, 4–15 mm (0.16–0.59 in) wide, stiff, 1-3 sharp teeth on the margins, rough with warty-based hairs. The yellow flower petals are oblanceolate-shaped, 8–10 mm (0.31–0.39 in) long, notched at the apex, disc florets about 50-100, bracts oval-shaped, 4–5 mm (0.16–0.20 in) long, peduncle rough and 3–16 cm (1.2–6.3 in) long. Flowering occurs from July to September and the fruit is dry, one seeded, wedge-shaped, brown, flattened, 3–4 mm (0.12–0.16 in) long with 2 or 3 narrow, dry wings.[2][3]
