description

Appearance and leaf

Eucalyptus baxteri grows as a tree that can reach heights of up to 40 meters. The bark remains on the entire tree, is gray to red-brown and fibrous. There are no oil glands in the marrow of the young branches or in the bark.

In Eucalyptus baxteri , heterophyllia is present. The leaves are always divided into a petiole and a leaf blade. The petiole is narrowly flattened or channel-shaped with a length of 10 to 20 mm. On young specimens, the leaf blade is broadly lanceolate, shiny green and hairy. On middle-aged specimens, the glossy green leaf blade is about 13 cm long and about 8 cm wide, also broadly lanceolate, straight and with entire margins. The glossy green leaves of the same color on the top and bottom of adult specimens are 7 to 13 cm long and 1.5 to 3.0 cm wide and lanceolate to broadly lanceolate, relatively thick, curved sickle-shaped and have a rounded shape or pointed upper end. The raised lateral nerves start at an acute or very acute angle at medium distances from the median nerve. The cotyledons ( cotyledons ) are kidney-shaped.

Inflorescence and flower

Lateral on 3 to 14 mm long and in cross-section stalk-round or angular inflorescence stem, seven to eleven flowers stand together in a single inflorescence . The pedicels are, if available, up to 4 mm long. The not blue-green floured or frosted flower buds are club-shaped with a length of 5 to 8 mm and a diameter of 4 to 5 mm. The sepals form a calyptra that remains in place until flowering ( anthesis ). The warty calyptra is conical, shorter than or as long as the smooth or warty flower cup (Hypanthium) and as wide as this. The flowers are white or creamy white.

fruit

The stalked or sessile fruit is 6 to 11 mm long and 8 to 16 mm in diameter, spherical or hemispherical and four to five pods. The disc is flat or indented, the fruit compartments are level with the rim or protrude slightly.

Occurrence

The natural range of Eucalyptus baxteri is the extreme southeast of New South Wales , the entire southern half of Victoria, and in South Australia the southeast and the Adelaide area .

Eucalyptus baxteri often grows locally in damp hard - leaved forests on relatively nutrient-poor loam soils and on the hills behind the coast.

Systematics

The first description was in 1867 by George Bentham under the name ( Basionym ) Eucalyptus santalifolia var.? baxteri Benth. in Flora Australiensis , Volume 3, p. 207. The type material is inscribed " S coast, probably Kangaroo Island, Baxter (Herb. R.Br.) ". The new combination to Eucalyptus baxteri (Benth.) Maiden & Blakely ex JMBlack was made in 1926 by John McConnell Black under the title Meliaceae - Scrophulariaceae in Flora of South Australia , Volume 3, p. 415. Other synonyms for Eucalyptus baxteri (Benth.) Maiden & Blakely ex JMBlack are: Eucalyptus baxteri (Benth.) Maiden & Blakely ex JMBlack . var baxteri , Eucalyptus baxteri var. pedicellata J.M.Black , Eucalyptus baxteri R.Br. ex Benth. nom. inval., Eucalyptus capitellata var. latifolia Benth.

Intergradations of Eucalyptus baxteri with Eucalyptus serraensis and Eucalyptus verrucata are known. Hybrids Eucalyptus baxteri × Eucalyptus diversifolia have been found in southwest Victoria.
