Angophora bakeri is a flowering plant in the myrtle family ( Myrtaceae ). It occurs on the east coast of New South Wales, where it is called "Narrow -leaved Apple " or "small -leaved Apple".

Description

Appearance and leaf

Angophora bakeri grows as a tree reaching heights of growth of up to 10 meters, or in the habit of Mallee Eucalyptus, this is a habit that is more shrub-like than tree-like, there are usually multiple strains available that form a Lignotuber. The bark remains on the entire tree is gray or pale brown and short-fibred.

In Angophora bakeri is available Heterophyllie. The simple leaves are always arranged alternately along the branches. The seated leaves are lanceolate in young specimens with a length of up to 7.5 cm and a width of about 1.3 cm; They have stiff, simple hairs and bristly glandular hairs ( trichomes ). 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 3-8 mm long. Their simple, bare leaf blade is at a length of 6 to 10 cm and a width of 0.5 to 1 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 midrib. The cotyledons ( cotyledons ) are nearly circular.

Inflorescence and flower

Terminally on a 7 to 18 mm long, bare or sparsely hairy stiff inflorescence stem are several partial inflorescences in total composite inflorescences. The bald or sparse stiff hairy flower stalk is 4-11 mm long. Flower bud having a length of 4 to 5 mm and a diameter of 4 to 6 mm. The hermaphrodite flowers are creamy white. The flower cup ( hypanthium ) is ribbed smooth or weak. The four sepals are reduced to four calyx teeth on the flower cups. The four petals have a width and length of about 3 mm.

Fruit and seeds

The stalked fruit is ovoid or cylindrical, with a length and a diameter of 8 to 10 mm and usually it tapers towards the tip. The disc is flat and covered by the edge of the flower cup or even depressed. The kneecap shaped seeds are regular and flattened, smooth and semi-gloss red.

Angophora bakeri grows mainly on sandy soils over sandstone.
