Corymbia Flavescens
''Corymbia flavescens'', commonly known as cabbage ghost gum, bastard ghost gum, scraggy cabbage gum, or wrinkle-leaf ghost gum, is a species of tree that is endemic to northern Australia. It has smooth powdery bark, egg-shaped to lance-shaped adult leaves, flower buds in groups of three, white flowers and variably-shaped fruit. The Jaru peoples know it as warlarri. Description ''Corymbia flavescens'' is a tree that typically grows to a height of and forms a lignotuber. It has smooth, powdery bark that is bright white when new and is shed in thin, greyish scales. Young plants and coppice regrowth have leaves that are yellowish green, heart-shaped to egg-shaped, long and wide on a short petiole. Adult leaves are mostly arranged alternately, more or less the same shade of yellow-green on both sides, egg-shaped to lance-shaped, long and wide, tapering to a petiole long. The flower buds are perfumed and arranged in leaf axils, appearing as if on a branched peduncle up to long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corymbia
''Corymbia'', commonly known as bloodwoods, is a genus of about one hundred species of tree that, along with ''Eucalyptus'', ''Angophora'' and several smaller groups, are referred to as eucalypts. Until 1990, corymbias were included in the genus ''Eucalyptus'' and there is still considerable disagreement among botanists as to whether separating them is valid. As of January 2020, ''Corymbia'' is an accepted name at the Australian Plant Census. Description Eucalypts in the genus ''Corymbia'' are trees, sometimes mallee-like, that either have rough, fibrous or flaky bark, or smooth bark that is shed in small flakes or short strips. Young plants and coppice regrowth have leaves that differ from adult leaves. The adult leaves are arranged alternately (strictly disjunct opposite, but appearing alternate), with oil glands. The flower buds are arranged in groups on a branching peduncle, each branch usually with seven buds, but with the pedicels of differing lengths, so that the infl ...

Epicormic Shoot
An epicormic shoot is a shoot growing from an epicormic bud, which lies underneath the bark of a trunk, stem, or branch of a plant. Epicormic buds lie dormant beneath the bark, their growth suppressed by hormones from active shoots higher up the plant. Under certain conditions, they grow into active shoots, such as when damage occurs to higher parts of the plant, or light levels are increased following removal of nearby plants. Epicormic buds and shoots occur in many woody species, but are absent from many others, such as most conifers. Function Human horticultural practices that exploit epicormic growth rely on plants that have epicormic budding capabilities for regenerative function in response to crown damage, such as through wind or fire. Epicormic shoots are the means by which trees regrow after coppicing or pollarding, where the tree's trunk or branches are cut back on a regular cycle. These forestry techniques cannot be used on species which do not possess strong epi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitchell Grass Downs
The Mitchell Grass Downs is a tropical and subtropical grasslands, savannas, and shrublands ecoregion in northeastern Australia.

Bioregion
A bioregion is an ecologically and geographically defined area that is smaller than a biogeographic realm, but larger than an ecoregion or an ecosystem, in the World Wide Fund for Nature classification scheme. There is also an attempt to use the term in a rank-less generalist sense, similar to the terms "biogeographic area" or "biogeographic unit". It may be conceptually similar to an ecoprovince. It is also differently used in the environmentalist context, being coined by Berg and Dasmann (1977). WWF bioregions The World Wide Fund for Nature (WWF) scheme divides some of the biogeographic realms into bioregions, defined as "geographic clusters of ecoregions that may span several habitat types, but have strong biogeographic affinities, particularly at taxonomic levels higher than the species level (genus, family)." The WWF bioregions are as follows: * Afrotropical realm ** Western Africa and Sahel **Central Africa ** Eastern and Southern Africa **Horn of Africa **Madagascar ...

Interim Biogeographic Regionalisation For Australia
The Interim Biogeographic Regionalisation for Australia (IBRA) is a biogeographic regionalisation of Australia developed by the Australian government's Department of Sustainability, Environment, Water, Population, and Communities. It was developed for use as a planning tool, for example for the establishment of a national reserve system. The first version of IBRA was developed in 1993–94 and published in 1995. Within the broadest scale, Australia Australia, officially the Commonwealth of Australia, is a Sovereign state, sovereign country comprising the mainland of the Australia (continent), Australian continent, the island of Tasmania, and numerous List of islands of Australia, sma ... is a major part of the Australasia biogeographic realm, as developed by the World Wide Fund for Nature.

Tanami Desert
The Tanami Desert is a desert in northern Australia, situated in the Northern Territory and Western Australia. It has a rocky terrain with small hills, and cacti. The Tanami was the Northern Territory The Northern Territory (commonly abbreviated as NT; formally the Northern Territory of Australia) is an Australian territory in the central and central northern regions of Australia. The Northern Territory shares its borders with Western Au ...'s final frontier and was not fully explored by Australians of European descent until well into the twentieth century. It is traversed by the Tanami Track. The name ''Tanami'' is thought to be an anglicisation of the Warlpiri language, Warlpiri name for the area, "Chanamee", meaning "never die". This referred to certain rock holes in the desert which were said never to run dry. Under the name Tanami bioregion, Tanami, the desert is classified as an Interim Biogeographic Regionalisation for Australia, interim Australian bioregion, co ...
