description

Appearance and leaf

Eucalyptus intertexta grows as a tree that can reach heights of up to 30 meters, but in Western Australia only 4 to 13 meters. The bark remains on the lower part of the trunk, is gray to red-brown with whitish spots and fibrous and lumpy. On the upper parts of the tree it is white or gray to red-brown and peels in short ribbons. The bark of the small branches is green. There are no oil glands in the marrow or in the bark.

In Eucalyptus intertexta is Heterophyllie ago. The leaves are always divided into a petiole and a leaf blade. On young specimens, the leaf blade is broadly lanceolate to ovate and dull green or blue-green floured and frosted. On middle-aged specimens, the dull green or blue-green floured and frosted leaf blade is about 12 cm long and about 5 cm wide, lanceolate to ovate, straight and with entire margins. The leaf stalk on adult specimens is 5 to 15 mm long. The leaf blade of the same color on the upper and lower side on adult specimens is 7 to 13 cm long and 1.0 to 2.2 cm wide, narrow-lanceolate to lanceolate, relatively thick, straight, tapers towards the base of the blade and has a pointed upper end. The side nerves, which are barely recognizable, extend from the median nerve at an acute angle at intermediate distances. The cotyledons ( cotyledons ) are reversed kidney-shaped.

Inflorescence and flower

Terminally or laterally on an inflorescence stem with a length of 5 to 16 mm in cross section, there are about seven flowers per single inflorescence or partial inflorescence in simple or compound inflorescences. The flower stalk is 3 to 9 mm long and stalk-round. The not blue-green floured or frosted flower buds are egg-shaped or club-shaped with a length of 6 to 8 mm and a diameter of 3 to 4 mm. The sepals form a calyptra that falls off early. The smooth calyptra is conical, shorter or as long as smooth flower cups (hypanthium) and narrower than this. The flowers are white or creamy white. All anthers are fertile. The flowering period in Western Australia extends from March to September.

fruit

The stalked fruit is 4 to 8 mm long and 4 to 7 mm in diameter cylindrical, hemispherical or egg-shaped and four to five-fold. The disc is indented, the fruit compartments are enclosed or at the level of the rim.

Occurrence

The natural range of Eucalyptus intertexta is the east of Western Australia , the northwest and east of South Australia , the south of the Northern Territory , the western and central New South Wales and the southeast of Queensland .

Eucalyptus intertexta occurs widespread, scattered, in mulga or acacia bushes on flat, light soils and in rocky terrain. In Western Australia, they can be found on red sand or clay , along drains and on plains.

Taxonomy

The first description of Eucalyptus intertexta was made in 1900 by Richard Thomas Baker in Proceedings of the Linnean Society of New South Wales , Volume 25, page 308, Table XVII. The type material has the inscription " Dubbo to the Darling River (" Gum ", W. Bauerlen); Nymagee, Condobolin ("Coolabah"); Mt. Hope ("Yellow Jacket" and "Gum"); Cobar ("Coolabah Gum"); Drysdale ("Coolabah"); Bodabah, 30 miles E. of Nymagee, one of the most easterly localities for this species. For these localities I am indebted to Mr. RH Cambage, (…) “. Synonyms for Eucalyptus intertexta RTBaker are Eucalyptus intertexta var. Fruticosa Blakely & Jacobs, Eucalyptus intertexta var. Diminuta Blakely and Eucalyptus intertexta RTBaker var. Intertexta .
