Appearance and leaf

Angophora costata grows as a tree reaching heights of growth of up to 30 meters. The bark is smooth, pink, gray or off- white and peels off in small pieces from.

In Angophora costata is available Heterophyllie. The simple leaves are always arranged alternately along the branches. The seated leaves on young specimens have stiff, simple hairs and bristly glandular hairs ( trichomes ). Their lamina is ovoid or elliptical, with a length of 12.5 cm and a width of about 6.5 cm. At middle-aged specimens the leaves are straight, entire and dull green. The leaves of adult specimens are divided into petiole and leaf blade. Your petiole is 10 to 25 mm long. Their simple, more or less bald leaf blade is at a length of 9 to 17 cm and a width of 2 to 3.5 cm lanceolate with pointed Spreitengrund and pointed or tapered at the top. The upper leaf surface and underside is colored differently. The lateral nerves go at close intervals from at an obtuse angle from the midrib. The cotyledons ( cotyledons ) are nearly circular.

Inflorescence and flower

Terminally on a 7 to 18 mm long, bald or hairy stiff inflorescence stem are several partial inflorescences in total composite inflorescences. The bald or stiff hairy flower stalk is 4-10 mm long. Flower buds are ovoid or spherical with a length of 5 to 7 mm and a diameter of 5 to 6 mm. The hermaphrodite flowers are creamy white. The four sepals are reduced to four calyx teeth on the heavily ribbed flower cup ( hypanthium ). The petals have a length and a width of 3 to 4 mm.

Fruit and seeds

The stalked fruit is ovoid or bell-shaped with a length of 9 to 15 mm and a diameter of 12 to 15 mm and sometimes they also tapers to the tip. The disc is pressed. The fruit trays are included. The kneecap shaped seeds are regular and flattened, smooth and semi-gloss red.


The main distribution area of Angophora costata located along the coast of New South Wales, from Coffs Harbour to Bodalla and in the Blue Mountains .. Sporadically it also occurs in the southeast and east of Queensland and in central Victoria. Angophora costata is widely scattered and locally common.

Angophora costata thrives mainly on deep sandy soils or sandy soils over sandstone.


The first publication was in 1788 by the German physician and botanist Joseph gardener under the name ( basionym ) Metrosideros costata Gaertn. in De fructibus et Seminibus Plantarum, Volume 1, page 171, Table 34, Figure 2 recombination to Angophora costata ( Gaertn. ) Britten took place in 1916 by the English botanist James Britten in the Journal of Botany, British and Foreign, Volume 54, S. 62 more synonyms for Angophora costata ( Gaertn. ) Britten are Metrosideros fulgens Sol. ex Gaertn. , Angophora costata ( Gaertn. ) Britten var costata, Angophora lanceolata var hispida A.Gray and Eucalyptus apocynfolia ( Salisb. ) Brooker.

According to " Australian Plant Name Index" 2006, there is Angophora costata of two subspecies, R. Govaerts et al. 2008, these are not recognized but separate species:

  • Angophora costata subsp. euryphylla LASJohnson ex GJLeach, Syn: Angophora europhylla ( GJLeach ) LASJohnson & KDHill, Eucalyptus europhylla ( LASJohnson ex GJLeach ) Brooker.
  • Angophora costata subsp. leiocarpa LASJohnson ex GJLeach, Syn: Angophora leiocarpa ( LASJonson ex GJLeach ) KRThiele & Chocoholics, Eucalyptus leiocarpa ( LASJohnson ex GJLeach ) Brooker.


Angophora costata is found in tropical and subtropical gardens as an ornamental plant. It is not frost hardy and is not used in temperate latitudes as an ornamental plant .. There are some varieties.

Known single copies

The Angophora Reserve in Avalon, a suburb of Sydney, was named after a large copy of Angophora costata. It was said to be about 300 years old and died at the end of the 20th century from.

The Angophora costata with the largest known trunk diameter (241 cm) is in Hobsonville in Auckland in New Zealand.
