Appearance and leaf

Eucalyptus longifolia grows as a tree that can reach heights of up to 35 meters and trunk diameters of up to 1 meter. The bark remains on the trunk and the larger branches, is gray, fibrous-scaly, soft white or gray on top, and peels off in short bands or scales.

In Eucalyptus longifolia , heterophyllia is present. The leaves on young specimens are ovate or broadly lanceolate and dull gray-green. The same-colored gray-green or matt blue-green leaves on adult specimens are narrow-lanceolate or lanceolate with a length of 10 to 25 cm and a width of 1.5 to 2.6 cm.

Inflorescence and flower

There are about three flowers in umbel-like inflorescences on each of the 11 to 34 mm long inflorescence shafts with round or angular cross-sections . The pedicel-round flower stalks are 4 to 20 mm long. The flower buds are spindle-shaped with a length of 14 to 26 mm and a diameter of 6 to 12 mm. The calyptra is conical and at least as long and wide as the flower cup (hypanthium).

fruit

The fruit is cylindrical, oval or bell-shaped with a length of 10 to 17 mm and a diameter of 9 to 16 mm. The disc is indented, the fruit compartments are enclosed or at the level of the rim.

ecology

Eucalyptus longifolia grows again from dormant buds after forest fires. The trees can live to be over 100 years old. The gray-headed fruit bat and Pteropus scapulatus feed on its flowers.

Occurrence

Eucalyptus longifolia is distributed from Morisett in the middle of the east coast of New South Wales to the border with Victoria . In the north of its range it occurs only sporadically, but is more common in the south, for example from Nowra to Bega . It generally grows on clay soils and in alluvial forests, and occasionally on poorly drained soils in valleys and low-lying areas. In light Hartlaub forests is Eucalyptus longifolia with eucalyptus acmenoides , Eucalyptus moluccana , Eucalyptus tereticornis and Angophora floribunda associated ; in swampy areas they are found together with Eucalyptus robusta and myrtle heather species such as Melaleuca linariifolia , Melaleuca stypheloides and Melaleuca ericifolia .

Systematics

The first description of Eucalyptus longifolia was made in 1822 by the German naturalist Johann Heinrich Friedrich Link in Enumeratio Plantarum Horti Regii Berolinensis Altera , 2, 29. A synonym for Eucalyptus longifolia Link is Eucalyptus woollsii F.Muell. The specific epithet longifolia is composed of the Latin words longus (German: long) and folium (German: leaf).

Eucalyptus longifolia belongs to Section Similares from the subgenus Symphyomyrtus within the genus Eucalyptus .

use

The dark red wood is hard and resists water and termites. It is used to make railway sleepers and other structural elements. Eucalyptus longifolia is also important for beekeeping . The tree provides shade and wind protection for pens, but is too big for private gardens.
