Description
editThe tree usually grows to about 5–6 m in height, though is occasionally found as an emergent up to 20 m. The bark is plated and hard, grey to greyish brown. The spirally arranged leaves are about 5–9 cm long by 2–4.5 cm wide. The flowers are yellow, with the inflorescences crowded at the ends of seasonal growth. The ovoid fruits are about 10–14 mm in diameter, containing flat seeds 4.25–6 mm long.[1]
Distribution and habitat
editThe species is known only from a restricted locality on the east coast of Queensland's Cape York Peninsula, north of Cooktown, in the Cape Bedford to Cape Flattery area. It grows on the grey or white sandy soils of Quaternary dunes, in closed forest dominated by Asteromyrtus angustifolia or Araucaria, at an altitude of 20–80 m.[1]
