Appearance and leaf

Angophora floribunda grows as a tree reaching heights of growth of up to 30 meters. The bark remains on the entire tree is gray or pale brown and short-fibred.

In Angophora floribunda is available Heterophyllie. The simple leaves are always arranged alternately along the branches. The leaves of young specimens are sitting and are covered with stiff, simple hairs and bristly glandular hairs ( trichomes ). They are broad - lanceolate, with a length of up to 9 cm and a width of about 3.5 cm or narrow - elliptic. At middle-aged specimens, the leaves are straight, entire and dull green. The leaves of adult specimens are divided into petiole and leaf blade. Your petiole is 8-12 mm long. Their simple leaf blade is are at a length of 8 to 12 cm and a width of 2 to 3 cm lanceolate with pointed Spreitengrund and pointed top. The leaf top and bottom is colored differently. The lateral veins are closely spaced at an obtuse angle to the main nerve. The cotyledons ( cotyledons ) are nearly circular.

The bald or stiff hairy flower stalk is 4-9 mm long. Flower buds are long and a length of 4 to 7 mm and a diameter of 5 to 7 mm spherical or ovoid. The hermaphrodite flowers are creamy white. The flower cup ( hypanthium ) is ribbed. The four sepals are reduced to four calyx teeth on the flower cups. The four petals have a length and a width of 3 to 4 per mm ..
