Angophora bakeri is a species ofthe myrtle family (Myrtaceae). It occurs on the east coast of New South Wales and is called there "Narrow-leaved Apple" or "Small-leaved Apple".
description
Appearance and leaf
Angophora bakeri grows as a tree that reaches heights of up to 10 meters, or 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 bakeri , heterophyllia is present. The simple leaves are always opposite to each other on the branches. The seated leaves on young specimens are lanceolate with a length of up to 7.5 cm and a width of about 1.3 cm; 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 3 to 8 mm long. Their simple, bald leaf blade is 6 to 10 cm long and 0.5 to 1 cm wide and lanceolate with a pointed base and a pointed upper end. The top and bottom of the leaves 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 7 to 18 mm long, bare or sparsely stiffly haired inflorescence stem, there are several partial inflorescences in composite inflorescences . The bald or sparse stiffly hairy flower stalk is 4 to 11 mm long. The flower buds have 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 smooth or slightly ribbed. The four sepals are reduced to four calyx teeth on the flower cup. The four petals have a width and length of about 3 mm.
Fruit and seeds
The stalked fruit is egg-shaped or cylindrical with a length and a diameter of 8 to 10 mm each and usually tapers towards the tip. The disc is flat and covered or even depressed by the edge of the flower cup. The kneecap-shaped seeds are regular and flattened, smooth and silk-matt red.
Occurrence
The main range of Angophora bakeri is around Sydney in eastern New South Wales , as well as in the extreme northeast of the state. The species is widespread and also common locally.
Angophora bakeri thrives mainly on sandy soils over sandstone .
Systematics
The first description of Angophora bakeri was made in 1913 by Carlotta Case Hall in Journal and Proceedings of the Royal Society of New South Wales , Volume 47, p 101. This type of material has the caption " Coastal district of New South Wales on Hawkesbury Sandstone around Sydney and Refer associated with Eucalyptus haemastoma and corymbosa ". The specific epithet bakeri honors the Australian botanist Richard Thomas Baker (1854–1941).
Synonyms for Angophora bakeri C.C. Hall are Angophora lanceolata var. Angustifolia A. Gray , Angophora bakeri C.C. Hall subsp. bakeri and Eucalyptus angustata Brooker .
According to the "Australian Plant Name Index" 2006 there are two subspecies of Angophora bakeri , according to the "World Checklist of Selected Plant Families" 2008, however, these are to be regarded as separate species:
- Angophora bakeri subsp. crassifolia G.J.Leach , Syn .: Angophora crassifolia (GJLeach) LASJohnson & KDHill , Eucalyptus crassifolia (GJLeach) Brooker .
- Angophora bakeri subsp. paludosa G.J.Leach , Syn .: Angophora paludosa (GJLeach) KRThiele & Ladiges , Syn .: Eucalyptus palustris Brooker , Angophora bakeri C.C.Hall subsp. bakeri .
