description
Appearance and leaf
Angophora melanoxylon grows as a tree that reaches heights of up to 15 meters, or often in the form of the mallee - eucalyptus , this is a growth form that is more shrub -shaped than tree-shaped , there are usually several trunks that form a lignotuber . The bark remains on the entire tree, is gray or pale brown and has short fibers.
In Angophora melanoxylon is Heterophyllie ago. The simple leaves are always opposite to each other on the branches. The sitting leaves on young specimens are lanceolate or narrowly elliptical with a length of up to 9 cm and a width of about 2.7 cm and covered with stiff, simple hairs and bristly glandular hairs ( trichomes ). On middle-aged specimens, the leaves are straight, with entire margins and matt green or blue-green floured or frosted. The leaves on adult specimens are divided into petiole and leaf blade. Your petiole is 1 to 4 mm long. Their simple, more or less stiffly hairy leaf blade is lanceolate or narrowly elongated with a length of 4 to 8 cm and a width of 0.7 to 1.8 cm with a mostly heart-shaped base and a pointed upper end. The top and bottom of the leaves are colored differently. The lateral nerves depart from the median nerve at close intervals at an obtuse angle. The cotyledons ( cotyledons ) are almost circular.
Inflorescence and flower
At the end of a 6 to 23 mm long, stiffly haired inflorescence stem, there are several partial inflorescences in combined total inflorescences . The stiffly hairy flower stalk is 3 to 9 mm long. The flower buds are egg-shaped or spherical with a length and a diameter of 4 to 6 mm each. The hermaphrodite flowers are creamy white. The flower cup (hypanthium) is ribbed. The four sepals are reduced to four calyx teeth on the flower cup. The four petals have a width and length of 3 to 4 mm.
Fruit and seeds
With a length of 8 to 13 mm and a diameter of 7 to 11 mm, the stalked fruit is ovoid or spherical and usually tapers towards the tip. The disc is indented and covered by the edge of the flower cup. The kneecap-shaped seeds are regular and flattened, smooth and silk-matt red.
Occurrence
The main distribution area of Angophora melanoxylon is around Sydney in northern New South Wales, north of Coolabah, as well as in adjacent southern Queensland. Angophora melanoxylon occurs locally but often sporadically.
Angophora melanoxylon thrives mainly on deep sandy soils .
Taxonomy
The first description of Angophora melanoxylon was made in 1900 by Richard Thomas Baker , entitled On a new species of Angophora in Proceedings of the Linnean Society of New South Wales , Volume 25 (1), page 84. The type material has the caption " Coolabah, NSW (Messrs. RH Cambage and W. Bäuerlein); West Bogan NSW (Mr RW Peacock) ”. Synonyms for Angophora melanoxylon F.Muell. ex RTBaker are Angophora intermedia var. melanoxylon (RTBaker) Maiden & Betche and Eucalyptus melana Brooker .
