description
Appearance and leaf
Angophora subvelutina grows as a tree that reaches heights of up to 20 meters. The bark remains on the entire tree, is gray or pale brown and has short fibers.
In angophora subvelutina is Heterophyllie ago. The simple leaves are always opposite to each other on the branches. The sessile leaves on young specimens are elongated; they have stiff, simple hair and bristly glandular hair ( trichomes ). On medium-aged specimens, the leaves are straight, entire and dull green. The leaves on adult specimens are divided into petiole and leaf blade. Your petiole is - if available - up to 2 mm long. Their simple, stiffly hairy leaf blade is egg-shaped or oblong with a length of 7 to 10 cm and a width of 3 to 5 cm with a heart-shaped base and a pointed upper end. The top and bottom of the leaf are colored differently. The lateral nerves are closely spaced at an obtuse angle to the median nerve. The cotyledons ( cotyledons ) are almost circular.
Inflorescence and flower
At the end of a 9 to 30 mm long, stiffly haired inflorescence stem, there are several partial inflorescences in composite inflorescences . The flower stalk is 3 to 10 mm long. The flower buds have a length and a diameter of 4 to 7 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 of about 3 mm and a length of 3 to 4 mm.
Fruit and seeds
The stalked fruit is egg-shaped with a length and a diameter of 7 to 10 mm and often tapers towards the tip. The disc is flat and covered or even depressed by the edge of the flower cup. The fruit compartments are included. The kneecap-shaped seeds are regular and flattened, smooth and silk-matt red.
Occurrence
Angophora subvelutina is only found in Queensland and New South Wales . The range of Angophora subvelutina is on the east coast of Australia, in the northern and central tableland and in the Great Dividing Range , from Bundaberg in the north to Araluen in the south. Angophora subvelutina is widespread and also common locally.
Angophora subvelutina thrives mainly on deep alluvial soil .
Taxonomy
The first description of angophora subvelutina was made in 1858 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae , Volume 1 (2), p 31. The type material has the inscription " In Pratis ad flumina Brisbane, Burnett et Boyd River, ubi" Apple Gum Tree " vocatur ”. The specific epithet subvelutina is derived from Latin and means "almost velvety". Synonyms for Angophora subvelutina F.Muell. are Angophora velutina F. Muell. orth. var. and Eucalyptus subvelutina (F. Muell.) Brooker .
