In Eucalyptus coolabah is Heterophyllie ago. The leaves on young specimens are lanceolate to broadly lanceolate and dull gray-green to blue-green. The same-colored, matt gray-green leaves on adult specimens are narrow-lanceolate to lanceolate with a length of 8 to 17 cm and a width of 1 to 2 cm.

Inflorescence and flower

On an inflorescence stem with a narrow, flattened or angular cross section, 1 to 9 mm long, there are approximately seven-flowered partial inflorescences in compound total inflorescences . The peduncle is 1 to 4 mm long. The blue-green frosted flower bud is egg-shaped with a length of 2 to 4.5 mm and a diameter of 2 to 3 mm. The calyptra is conical, longer than the flower cup (hypanthium) and just as wide as this. All stamens are fertile (fertile). The stamens are irregularly curved in the bud. The anthers are elongated.

fruit

The fruit is spherical or hemispherical with a length and a diameter of 2 to 4 mm. The disc is flat and narrow, the fruit fans protrude.

Occurrence

Eucalyptus coolabah at the natural site

Eucalyptus coolabah is a dominant species in some locations and grows in grassy, sparse forests on heavy clay soils near perennial waters . The main distribution area extends from western and northern New South Wales over southern and central Queensland over the middle of the continent to the north of Western Australia .

Systematics

The first description of Eucalyptus coolabah was made in 1934 by William Faris Blakely in A Key to the Eucalypts , pp 245-246. Eucalyptus microtheca F.Muell is a synonym for Eucalyptus coolabah Blakely & Jacobs .

  • Eucalyptus coolabah subsp. arida (Blakely) LASJohnson & KDHill, Syn .: Eucalyptus coolabah var. arida Blakely: Buds, fruits and twigs blue-green, calyptra rounded and blunt, leaves on adult specimens thick.
  • Eucalyptus coolabah Blakely & Jacobs subsp. coolabah : buds, fruits and branches not blue-green.

Folk song

In the Australian folk song Waltzing Matilda is Eucalyptus coolabah mentioned:

Once a jolly swagman camped by a billabong,
Under the shade of a coolibah tree,
And he sang as he watched and waited till his billy boiled,
You'll come a-Waltzing Matilda with me.
