Harpullia hillii, commonly known as blunt-leaved tulip or oblong-leaved tulip, is a tree in the family Sapindaceae, endemic to eastern Australia.Although the species may grow to 20 metres high, most trees are less than 10 metres high. Each leaf comprises 4 to 12 leaflets, that are oblong or elliptic oblong and between 5 and 15 cm long and 2 to 6 cm wide. White flowers with petals 10–12 mm long appear in panicles that are 10–25 cm long. These are followed by orange fruit that are 25–30 mm in diameter and 12–14 mm long. The fruit, which is positioned above the persistent sepals, becomes woody with age. The glossy black seeds protrude from red arils.
