description
Appearance and leaf
Eucalyptus longicornis grows as a tree or, rarely, as a mallee , reaching heights of 2 to 24 meters, sometimes even 30 meters. The bark remains on the trunk and the larger branches, is gray or gray-black and has short fibers. There are no oil glands in the marrow or in the bark.
In Eucalyptus longicornis is Heterophyllie ago. The leaves are always divided into a petiole and a leaf blade. The petiole is narrowly flattened or channel-shaped. On middle-aged specimens, the leaf blade is broadly lanceolate to ovate, straight, with entire margins and a dull gray-green. The leaf blades, glossy green on the top and bottom of the adult specimens, are narrow-lanceolate, relatively thick, straight, taper towards the base of the blade and have a pointed upper end. The side nerves, which are barely recognizable, extend from the middle nerve at an acute or obtuse angle. The cotyledons ( cotyledons ) are in two parts.
Inflorescence and flower
On the side of an inflorescence stem that is round in cross section, there are three, seven or up to eleven flowers together in a simple inflorescence . The flower buds are egg-shaped or cylindrical and not floured or frosted blue-green. The sepals form a calyptra that falls off early. The smooth calyptra is conical, three times as long as the smooth flower cup (hypanthium) and narrower than or as wide as this. The flowers are white, creamy white or yellow. The flowering period in Western Australia extends from December or January to February.
fruit
The fruit is spherical. The disc is pushed in and the fruit fans stick out.

Taxonomy
It was first described in 1878 by Ferdinand von Mueller as a variety ( Basionym ) Eucalyptus oleosa var. Longicornis F. Muell. in Fragmenta Phytographiae Australiae , Volume 11, 88, p. 14. The type material has the inscription “sub nomine 'Morel' in Australia occidentali”. The new combination to Eucalyptus longicornis (F.Muell.) Maiden took place in 1919 by Joseph Maiden in Journal and Proceedings of the Royal Society of New South Wales , Volume 52, p. 504. Other synonyms for Eucalyptus longicornis (F.Muell.)
