Elaeocarpus ferruginiflorus is a species of flowering plant in the family Elaeocarpaceae and is endemic to north-east Queensland. It is a small to medium-sized tree, sometimes with buttress roots at the base of the trunk, elliptic to egg-shaped leaves, flowers with five white petals, and dark bluish-grey fruit.

Description
Elaeocarpus ferruginiflorus is a tree that typically grows to a height of 8–20 m, 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 long and 15–35 mm wide on a petiole 5–12 mm long. The flowers are borne in groups of up to about ten on a rachis 20–50 mm long, each flower on a pedicel 3–4 mm long. The flowers are densely covered with woolly reddish brown hairs. The five sepals are 5–6 mm long and 2–3 mm wide, the five petals thick, about 6 mm long and 1.5 mm 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 long and 11 mm wide, present from July to October.
