Angophora costata subsp. leiocarpa L.A.S. Johnson ex G.J. Leach

Angophora costata, or Smooth-barked Apple, is a large, wide, spreading tree growing to a height of between 15 and 25 m. The trunk is often gnarled and crooked with a pink to pale grey, sometimes rusty-stained bark. The timber is rather brittle. In nature the butts of fallen limbs form callused bumps on the trunk and add to the gnarled appearance. The old bark is shed in spring in large flakes with the new salmon-pink bark turning to pale grey before the next shedding.
The leaves are dark green, lance-shaped, 6-16 cm long and 2-3 cm wide. They are borne opposite each other on the stem.
The flowers are white and very showy, being produced in large bunches on terminal corymbs or short panicles. The individual flowers are about 2 cm wide with five tooth-like sepals, five larger semi-circular petals, and a large number of long stamens. The seed capsules are goblet shaped, 2 cm long and as wide, often with fairly prominent ribs. The usual recorded flowering time is December or January, but at the Australian National Botanic Gardens in Canberra the species flowers for about one month between early January and early February. The tree has a handsome, rugged ornamental appearance and its young red tips are often used in floral arrangements.
