Hovea Elliptica
''Hovea elliptica'', commonly known as the tree hovea or karri blue bush, is an ornamental plant in the family Fabaceae that is native to Western Australia. This plant was cited as ''Hovea Celsi'' in ''Description des plantes rares cultivees a Malmaison et a Navarre'' by Aimé Jacques Alexandre Bonpland. Description The erect and slender shrub or small tree typically grows to a height of . It is usually single stemmed and the young branches are covered in spreading often rust coloured hairs. The stipules are narrow triangular and around in length. The alternately arranged leaves have an elliptical blade to around in length. The species has purple or blue flowers that appear between August and December in its native range. The pea shaped flowers are arranged in short clusters among the leaf axils. The axillary inflorescences contain one to seven flowers. The seed pods that form later are ovoid to ellipsoid in shape and are in length and wide. The olive brown seeds within ha ...

James Edward Smith (botanist)
__NOTOC__ Sir James Edward Smith (2 December 1759 – 17 March 1828) was an English botanist and founder of the Linnean Society. Early life and education Smith was born in Norwich in 1759, the son of a wealthy wool merchant. He displayed a precocious interest in the natural world. During the early 1780s he enrolled in the medical course at the University of Edinburgh where he studied chemistry under Joseph Black and natural history under John Walker. He then moved to London in 1783 to continue his studies. Smith was a friend of Sir Joseph Banks, who was offered the entire collection of books, manuscripts and specimens of the Swedish natural historian and botanist Carl Linnaeus following the death of his son Carolus Linnaeus the Younger. Banks declined the purchase, but Smith bought the collection for the bargain price of £1,000. The collection arrived in London in 1784, and in 1785 Smith was elected Fellow of the Royal Society. Academic career Between 1786 and 1788 Smit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Rosids Of Western Australia
The rosids are members of a large clade (monophyletic group) of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification. These orders, in turn, together comprise about 140 families. Fossil rosids are known from the Cretaceous period. Molecular clock estimates indicate that the rosids originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's forests are highly dominated by rosid species, which in turn helped with diversification in many other living lineages. Additionally, rosid herbs and shrubs are also a significant part of arctic/alpine, temperate floras, aquatics, desert plants, and parasites. Name The name is based upon the name "Rosidae", which had usually been understood to be a subclass. In 1967, Armen Takhtajan showed that the correct basis for the name "Rosidae" is a description of a group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hovea
''Hovea'' is a genus of about forty species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in this genus are sub-shrubs, shrubs or small trees with simple leaves and purple, blue or mauve flowers with a white centre. The fruit is a pod containing brown to blackish seeds. Species of ''Hovea'' occur in all Australian states, the Australian Capital Territory and the Northern Territory.
