description

Appearance and leaf

Eucalyptus tricarpa grows as a tree that can reach heights of up to 35 meters. The bark remains on the entire tree, is red-brown to brown-black and deeply furrowed. 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 tricarpa is Heterophyllie ago. The leaves are always divided into a petiole and a leaf blade. The leaf blade on seedlings is slightly different in color on the top and bottom and is lanceolate to ovate with a length of 4 to 9.5 cm and a width of 1.5 to 4 cm. On young specimens, the leaf blades are dull green or gray-green on the top and bottom of the same color, with a length of 9.5 to 17 cm and a width of 3 to 5 cm broadly lanceolate to ovate. On medium-old specimens, the leaf blade is 11 to 21 cm long and 2 to 3.5 cm wide and lanceolate, broadly lanceolate or ovate, straight, with entire margins and dull green. The leaf stalks on adult specimens are narrowly flattened or channel-shaped with a length of 13 to 25 mm. The leaf blades on adult specimens with the same color, matt green upper and lower sides, are 9 to 22 cm long and 1 to 2.4 cm wide, lanceolate, relatively thick, curved sickle-shaped, taper towards the base of the blade and have a pointed upper one The End. The raised lateral nerves extend from the median nerve at large intervals at an acute angle. The cotyledons ( cotyledons ) are upside-kidney-shaped.

Inflorescence and flower

End or lateral on a 5 to 17 mm long in cross-section pedunculate or angular inflorescence stem are in simple inflorescence only about three flowers. The flower stalks are 10 to 18 mm long with round or angular stems. The not blue-green floured or frosted flower buds are egg, club-shaped or short spindle-shaped with a length of 10 to 14 mm and a diameter of 5 to 7 mm. The sepals form a calyptra that remains in place until flowering ( anthesis ). The smooth calyptra is conical or beak-shaped, shorter than or as long as the smooth flower cup (hypanthium) and as wide as this. The flowers are white, pink, cream or red. The outer stamens are sterile (infertile), the anthers are cubic. The flowering period extends from May to October.

Fruit and seeds

The stalked fruit is 10 to 14 mm long and 10 to 15 mm in diameter spherical, hemispherical, egg-shaped or urn-shaped and four, five or six-faced. The disc is indented, the fruit compartments are included.

The brown or gray seed is ovate or compressed ovoid. The hilum is in the middle.

Occurrence

The natural range of Eucalyptus tricarpa is the southern coastline of New South Wales south of Araluen as well as the east, the south and the center of Victoria .

Eucalyptus tricarpa occurs locally often in dry hard- leaved forest or light forest on moderately fertile, flat soils .

Systematics

It was first described in 1962 by Lawrence Alexander Sidney Johnson as a subspecies ( Basionym ) Eucalyptus sideroxylon subsp. tricarpa L.ASJohnson from Eucalyptus sideroxylon under the title Studies in the Taxonomy of Eucalyptus in Contributions from the New South Wales National Herbarium , Volume 3, Issue 3, p. 122. The type material has the inscription “Tilba Tilba to Wallaga Lake, NSW, LASJohnson November 20, 1950 (NSW 54090), flowering and fruiting " . LASJohnson and KDHill gave her the rank of a species of Eucalyptus tricarpa (LASJohnson) LASJohnson & KDHill in 1991 under the title Systematic studies in the eucalypts. 3. New taxa in Eucalyptus (Myrtaceae) in Telopea , Volume 4, Issue 2, p. 247. The specific epithet tricarpa is derived from the Latin words “tri” for three and “carpas” for fruit and indicates the three-flowered inflorescence (and triple fruit cluster).

Since 2004 there are two subspecies of Eucalyptus tricarpa (LASJohnson) LASJohnson & KDHill :

Eucalyptus tricarpa subsp. decora Rule : This subspecies was published by K. Rule in Muelleria , Volume 20, 2004, p. 27.
Eucalyptus tricarpa (LASJohnson) LASJohnson & KDHill subsp. tricarpa

There are natural hybrids of Eucalyptus tricarpa and Eucalyptus bosistoana .

use

The heartwood of Eucalyptus tricarpa is dark red, very hard and extremely durable. It has a specific weight of 910 to 1220 kg / m³. The common name "Red Ironbark" refers to the red hard wood. The wood of eucalyptus tricarpa used for railroad ties and other heavy constructions.
