description
Appearance and leaf
Eucalyptus michaeliana grows as a tree that can reach heights of up to 30 meters. The bark is smooth, white, gray, or reddish brown and peels off in plates or patches.
In Eucalyptus micheliana , heterophyllia is present. The leaves are always divided into a petiole and a leaf blade. On young specimens, the leaf blade is lanceolate, later broadly lanceolate, and dull green. The leaf blades of the same color or slightly different colors on the top and bottom of the adult specimens are lanceolate with a length of 12 to 20 cm and a width of 2 to 3 cm. The cotyledons ( cotyledons ) are upside-kidney-shaped.
Inflorescence and flower
On the side of a 5 to 10 mm long inflorescence stem with a round pedicel in cross-section, there are approximately three to seven-flowered partial inflorescences in compound total inflorescences . The 2 to 5 mm long flower stalks are stalk-round. The flower buds are ovoid or obovate with a length of 3 to 5 mm and a diameter of 2 to 3 mm. The sepals form a calyptra that falls off early. The calyptra is hemispherical or conical, shorter than the flower cup (hypanthium) and as wide as this.
fruit
The fruit is hemispherical or cylindrical with a length and a diameter of 4 to 5 mm. The disc is flat or slightly raised, the fruit compartments are enclosed or are level with the edge.
Occurrence and endangerment
The natural range of Eucalyptus michaeliana is the east and northeast of New South Wales , with isolated populations from Wollombi to St. Albans and east of Armidale .
Eucalyptus michaeliana often grows locally in dry hard deciduous forests on sandy soils .
Eucalyptus michaeliana is classified as ROTAP: 3RCa on New South Wales' Endangered Species List.
Taxonomy
The first description of eucalyptus michaeliana was made in 1938 by William Faris Blakely in Proceedings of the Linnean Society of New South Wales , Volume 63, page 67. The type material has the caption " NSW - At Hillgrove and Enmore (JF Campbell, March 1907), the type “.
