Description
editElaeocarpus ferruginiflorus is a tree that typically grows to a height of 8–20 m (26–66 ft), sometimes with buttress roots at the base of the trunk. Its young leaves and shoots are densely covered with rust-coloured hairs. The leaves are elliptic to egg-shaped with the narrower end towards the base, 35–60 mm (1.4–2.4 in) long and 15–35 mm (0.59–1.38 in) wide on a petiole 5–12 mm (0.20–0.47 in) long. The flowers are borne in groups of up to about ten on a rachis 20–50 mm (0.79–1.97 in) long, each flower on a pedicel 3–4 mm (0.12–0.16 in) long. The flowers are densely covered with woolly reddish brown hairs. The five sepals are 5–6 mm (0.20–0.24 in) long and 2–3 mm (0.079–0.118 in) wide , the five petals thick, about 6 mm (0.24 in) long and 1.5 mm (0.059 in) wide, sometimes with about three indistinct teeth on the tip, and there are forty stamens. Flowering mainly occurs in January and the fruit is a more or less spherical or oval, dark bluish-grey drupe about 17 mm (0.67 in) long and 11 mm (0.43 in) wide, present from July to October.[2][3]
