description

Appearance and leaf

Eucalyptus banksii grows as a tree that can reach heights of up to 30 meters. The bark remains on the trunk and the larger branches, is gray with whitish spots and fibrous and lumpy. At the top of the tree, it is smooth, gray, and peels in short ribbons. The small twigs have a green bark. There are oil glands in the marrow, but not in the bark.

In Eucalyptus banksii there is heterophyllia . The leaves on young specimens are opposite, sessile, and matt gray-green or blue-green frosted or floured. Their leaf blades are circular to heart-shaped, ovate, notched and straight, with a length of about 12 cm and a width of about 0.7 cm. The leaf stalks on adult specimens are narrowly flattened or channel-shaped with a length of 20 to 30 mm. The glossy green leaves on adult specimens with the same colored upper and lower sides are 12 to 20 cm long and 2 to 3 cm wide, lanceolate, relatively thick, taper towards the base of the blade and have a pointed or pointed upper end. The side nerves, which are barely recognizable, extend from the middle nerve at medium intervals at an acute or very acute angle. The cotyledons ( cotyledons ) are almost circular.

Inflorescence and flower

On an inflorescence shaft with round peduncles in cross section, 2 to 8 mm long, there are approximately seven-flowered partial inflorescences . The flower buds can be sessile or there may be a pedicel-round flower stalk. The egg-shaped or short-cylindrical flower buds are 4 to 6 mm long and 3 to 5 mm in diameter and are not floured or frosted blue-green. The sepals form a calyptra that falls off early. The smooth calyptra is hemispherical or conical, as long as the smooth flower cup (hypanthium) or shorter and as wide or narrower than this. The flowers are white or creamy white.

fruit

The non-stalked fruit is 4 to 6 mm long and 5 to 7 mm in diameter, spherical or hemispherical and three to four-fold. The disc is flat or raised, the fruit compartments protrude.

Occurrence

The natural range of Eucalyptus banksii is north of Armidale east of Tenterfield (in which the common English name is based) in the extreme northeast of New South Wales and in the adjacent southeast Queensland .

Eucalyptus banksii grows sporadically, but also often locally, in dry hard-leaved forests .

Taxonomy

The first description of Eucalyptus banksii was made in 1905 by Joseph Maiden , entitled Miscellaneous notes (chiefly taxonomic) on Eucalyptus. I. in Proceedings of the Linnean Society of New South Wales , Volume 29, Issue 4, p. 774. The type material has the inscription “ On the sides of hills at an elevation of about 3,500 feet in the Wallangarra (New South Wales-Queensland border) district (JL Boorman, August, 1904); Emmaville (JL Boorman, October, 1901) ”. Maiden writes: "I dedicate this interesting species in honor of the great Sir Joseph Banks." (translated into German: I dedicate this interesting species to the great Sir Joseph Banks). Therefore, the specific epithet banksii honors the English naturalist, especially the botanist Joseph Banks .
