Appearance and leaf

Eucalyptus pilularis grows as a tree that reaches heights of up to 70 meters. The bark remains on the entire trunk, is gray-brown and fibrous to short-fibred. On the upper parts of the tree it is white to gray and peels in long ribbons. The bark of the small branches is green. There are no oil glands in the marrow of the young branches or in the bark.

In Eucalyptus pilularis is Heterophyllie ago. The leaves on young specimens are sessile, broadly lanceolate and dull green. On medium-old specimens, the leaves are about 17 cm long and about 4 cm wide, also broadly lanceolate, straight, with entire margins and dull green. In adult specimens, the leaves are divided into a petiole and a leaf blade. Your petiole is 10 to 20 mm long. Their leaf blades, which are glossy green on the top and bottom, are 9 to 16 cm long and 1.5 to 3 cm wide, lanceolate, relatively thick, straight, have a blunt blade base and a pointed or tapered upper end. The raised lateral nerves branch off from the median nerve at medium intervals at an acute angle. The cotyledons ( cotyledons ) are kidney-shaped.

Inflorescence and flower

On the side of an inflorescence stem with a length of 10 to 17 mm and a diameter of up to 3 mm in cross-section, with a narrow flattened or angular inflorescence stem, there are about seven to fifteen flowers together in a simple inflorescence (see photo). The flower stalks are 3 to 6 mm long and stalk-round. The not blue-green floured or frosted flower buds are club-shaped or spindle-shaped with a length of 7 to 10 mm and a diameter of 3 to 5 mm. The sepals form a calyptra that remains in place until anthesis . The smooth calyptra is conical or beak-shaped, two to three times as long as the smooth flower cup (hypanthium) and just as wide as this. The flowers are white or creamy white.

fruit

The stalked fruit is 6 to 11 mm long and 7 to 11 mm in diameter spherical, hemispherical or egg-shaped and four-faced. The disc is flat or indented, the fruit compartments are enclosed or at the level of the rim.

Occurrence

The natural range of Eucalyptus pilularis is the entire coast of New South Wales and its hinterland as well as the southeast of Queensland .

Eucalyptus pilularis thrives widely and often dominantly in moist hard foliage - or grassy, ​​light coastal forest on lighter, moderately fertile soils .

ecology

Eucalyptus pilularis has a high proportion of many endangered plant communities , for example the “Blue Gum High Forest”, the “Illawarra Lowlands”, the “Bangalay Sandy Forest” and the grassy, ​​light forests.

Eucalyptus pilularis is one of the koalas' fodder plants .

The first publication of Eucalyptus pilularis was made in 1797 by James Edward Smith titled Botanical Characters of Some Plants of the Natural Order of Myrti in Transactions of the Linnean Society of London , Volume 3, page 284. synonyms for Eucalyptus pilularis Sm.

Well-known single copies

In Middle Brother National Park there are two well-known, old specimens of Eucalyptus pilularis : “Benaroon” is 64 meters high and has a trunk diameter of 4.1 meters at chest height. "Bird Tree" has a height of 69 meters and a diameter of 3.59 meters at chest height . A specimen 85 meters high was felled near Bulli.

use

The heartwood of Eucalyptus pilularis is yellow-brown to light brown, hard and durable. Its specific weight is around 900 kg / m³. The wood from Eucalyptus pilularis is used to make posts, railroad ties, floors, decks, siding, joints and wood chips.
