Macadamia ternifolia (common names: small-fruited Queensland nut, gympie nut)[5] is a tree in the flowering plant family Proteaceae, native to Queensland in Australia,[2][3] and is listed as vulnerable under the EPBC Act.[5]
Macadamia ternifolia is a small multi-stemmed tree which grows up to 8 m tall. The narrowly ovate adult leaves are in whorls of three on a stalk which is 4–10 mm long.[3] Each leaf is 9–12.5 cm long, 2–3.5 cm wide and is dull above and paler below.[3] They are stiff, smooth and leathery, with slightly undulating margins and points at the tip.[3] The midrib is prominent below, and slightly sunken above.[3] Inflorescence is simple on a stem 5–18 cm long, with pink tepals 6–8.5 mm long, and filaments 4–7 mm long which are joined to the tepals for 0.5–6 mm and anthers 1–2 mm long.[3] The ovaries 0.4–1 mm long and the style 5–10 mm long, and give rise to fruit which is 14–22 mm long and 13–22 mm wide.[3] The seeds are globose to broadly ovoid and about 16 mm long and 12 mm wide and have a smooth shell about 1 mm thick.[3]
