Appearance and leaf
Eucalyptus ebbanoensis grows in the form of the mallee - eucalyptus , this is a growth form that is more shrub -shaped than tree-shaped , there are usually several trunks that form a lignotuber ; it reaches heights of growth of up to 2 to 10 meters. The bark is smooth, gray, gray-brown or brown all over the tree and peels in short bands or small, polygonal patches. There are oil glands in both the bark and the marrow of the young branches.
In Eucalyptus ebbanoensis , heterophyllia is present. On medium-old specimens, the leaves are sessile, elliptical, straight, with entire margins and matt gray-green. The leaves on adult specimens are dull green, sometimes opposite, of the same color on the upper and lower sides, are narrowly lanceolate, relatively thin, curved in a sickle shape and taper towards the base of the blades. The side nerves, which are barely recognizable, extend from the median nerve at an acute or very acute angle. The cotyledons ( cotyledons ) are kidney-shaped.
Inflorescence and flower
On the side of an inflorescence stem with a round pedicel in cross-section, there are approximately three-flowered partial inflorescences in compound total inflorescences . The flower buds are pear-shaped and not floured or frosted blue-green. The sepals are reduced to four calyx teeth on the flower cup (hypanthium). The smooth calyptra is hemispherical, as long and as wide as the smooth flower cup (hypanthium). The flowers are white or creamy white. The stamens are in four bundles. The flowering period in Western Australia ranges from September to December or January to March.
fruit
The stalked fruit is hemispherical. The disc is raised, the fruit fans stick out.
