Plants Described In 1867
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosperm ...

Fagales Of Australia
The Fagales are an order of flowering plants in the rosid group of dicotyledons, including some of the best-known trees. Well-known members of Fagales include: beeches, chestnuts, oaks, walnut, pecan, hickory, birches, alders, hazels, hornbeams, she-oaks, and southern beeches. The order name is derived from genus ''Fagus'' (beeches). Systematics Fagales include the following seven families, according to the APG III system of classification: *Betulaceae – birch family (''Alnus'', ''Betula'', ''Carpinus'', ''Corylus'', ''Ostrya'', and ''Ostryopsis'') *Casuarinaceae – she-oak family (''Allocasuarina'', ''Casuarina'', ''Ceuthostoma'', and ''Gymnostoma'') *Fagaceae – beech family (''Castanea'', ''Castanopsis'', ''Chrysolepis'', ''Fagus'', ''Lithocarpus'', ''Notholithocarpus'', ''Quercus'', and '' Trigonobalanus'') *Juglandaceae – walnut family (''Alfaroa'', ''Carya'', '' Cyclocarya'', '' Engelhardia'', ''Juglans'', ''Oreomunnea'', ''Platycarya'', ''Pterocarya'', and ''Rhoi ...

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 may have originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's broadleaved forests are dominated by rosid species, which in turn help with diversification in many other living lineages. Additionally, rosid herbs and shrubs are a significant part of arctic/alpine and temperate floras. The clade also includes some aquatic, desert and parasitic plants. 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 na ...

Allocasuarina
''Allocasuarina'', commonly known as sheoak or she-oak, is a genus of flowering plants in the family Casuarinaceae and is endemic to Australia. Plants in the genus ''Allocasuarina'' are trees or shrubs with soft, pendulous, green branchlets, the leaves reduced to scale-like teeth. Allocasuarinas are either monoecious or dioecious, the flowers never bisexual. Male and female flowers are arranged in spikes, the female spikes developing into cone-like structures enclosing winged seeds. The genera ''Allocasuarina'' and '' Casuarina'' are similar, and many formerly in the latter now included in ''Allocasuarina''. Description Plants in the genus ''Allocasuarina'' are trees or shrubs with soft, pendulous, green branchlets, the leaves reduced to 4 to 14 scale-like teeth arranged around in whorls around ribbed, jointed branchlets. Allocasuarinas have separate male and female flowers, sometimes on one plant (monoecious), otherwise on separate male and female plants, (dioecious). Male fl ...

The Avon Wheatbelt is a bioregion in Western Australia. It has an area of . It is considered part of the larger Southwest Australia savanna ecoregion. Geography The Avon Wheatbelt bioregion is mostly a gently undulating landscape with low relief.
