Bosistoa floydii, commonly known as the five-leaf bosistoa[2] or five-leaved bonewood,[3] is a species of small rainforest tree that is endemic to north-eastern New South Wales. It has pinnate leaves usually with five elliptic leaflets, and panicles of tiny, creamy white flowers.
Bosistoa floydii grows as a small tree that may reach 15–20 m (49–66 ft) high and has a spreading crown. The trunk is buttressed and can reach a diameter of 75 cm (30 in), and the bark is grey. The leaves are arranged in opposite pairs on thick green or fawn branches and are pinnate, 110–280 mm (4.3–11.0 in) long on a petiole 20–50 mm (0.8–2 in) long. There are three to seven, usually five glossy elliptical leaflets, each 65–160 mm (2.6–6.3 in) long and 15–35 mm (0.6–1 in) wide on a petiolule 5–25 mm (0.2–1 in) long. The leaflets have prominent oli glands and a pointed tip. Appearing in October and November, the tiny flowers are arranged in panicles up to 200 mm (7.9 in) long. Each flower has five hairy sepals about 1 mm (0.04 in) long and five oval, white or creamy white petals 4–5 mm (0.16–0.20 in) long. Flowering is followed by one, or rarely two small, warty, woody, yellow-brown fruit that ripen in February.[2][3][4]
