description
Appearance and leaf
Eucalyptus laeliae grows as a tree that reaches heights of 5 to 20 meters. The bark is smooth and powdery white all over the tree. There are oil glands in the marrow of the young branches, but not in the bark.
In Eucalyptus laeliae , heterophyllia is present. The leaves are always divided into a petiole and a leaf blade. The leaf blade on medium-old specimens is dull gray-green with the same color on the top and bottom and is elliptical to ovate, straight and with entire margins. The leaf stalks on adult specimens are narrowly flattened or channel-shaped. The leaf blades of the same color on the upper and lower sides on adult specimens are lanceolate, curved sickle-shaped, relatively thin, 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 with a width of up to 3 mm in cross section, there are about three, seven or up to eleven flowers together in a simple inflorescence . The flower buds are obovate or spindle-shaped and not floured or frosted blue-green. The sepals form a calyptra that falls off early. The smooth calyptra is hemispherical or conical, as long and as wide as the smooth flower cup (hypanthium). The flowers are white or creamy white. The flowering period in Western Australia extends from December or January to February.
fruit
The fruit is hemispherical. The disc is pressed in, the fruit fans stick out.

Taxonomy
The first description of eucalyptus laeliae was made in 1969 by Francis Denis Podger and George McCartney Chippendale in the Journal of the Royal Society of Western Australia , Volume 51, page 65, Figures 1-3. The type material has the inscription " 1.8 miles south east of North Dandalup on Whittakers Hill Road, about 43 miles south of Perth, Western Australia, 13/10/1966. L. McGrann (FRI 13813).
