Corymbia Mannifera
''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 inflor ...

Corymbia Ficifolia
''Corymbia ficifolia'' ( syn. ''Eucalyptus ficifolia'', commonly known as the red flowering gum, is a species of small tree that is endemic to the south-west of Western Australia. It has rough, fibrous bark on the trunk and branches, egg-shaped to broadly lance-shape adult leaves, flower buds in groups of seven, bright red, pink or orange flowers and urn-shaped fruit. It has a restricted distribution in the wild but is one of the most commonly planted ornamental eucalypts. Description ''Corymbia ficifolia'' is a straggly tree that typically grows to a height of and forms a lignotuber. It has rough, fibrous brownish bark on the trunk and branches. The adult leaves are dull to slightly glossy, paler on the lower surface, egg-shaped to broadly lance-shaped, long and wide, tapering to a petiole long. The flower buds are arranged on the ends of branchlets on a branched peduncle long, each branch of the peduncle with seven buds on pedicels long. Mature buds are oval to pear-s ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Multi-access Key
In biology or medicine, a multi-access key is an identification key which overcomes the problem of the more traditional single-access key In phylogenetics, a single-access key (also called dichotomous key, sequential key, analytical key, or pathway key) is an identification key where the sequence and structure of identification steps is fixed by the author of the key. At each point i ...s (dichotomous or polytomous identification keys) of requiring a fixed sequence of identification steps. A multi-access key enables the user to freely choose the characteristics that are convenient to evaluate for the item to be identified.Pankhurst, R. J. 1991. Practical Taxonomic Computing.Winston, J. 1999. Describing Species. Columbia University Press. Although good single-access keys will try to start with characters that are reliable, convenient to observe and generally available throughout most of the year, it is often impossible to achieve this for all taxa in a key. A multi-access key lets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Allosyncarpia
''Allosyncarpia ternata'', commonly known as ''an-binik'', is a species of rainforest trees constituting part of the botanical family Myrtaceae and included in the eucalypts group. The only species in its genus, it was described in 1981 by Stanley Blake of the Queensland Herbarium. They grow naturally into large, spreading, shady trees, and are endemic to the Northern Territory of Australia. They grow in sandstone gorges along creeks emerging from the Arnhem Land plateau. The common name ''anbinik'' comes from the Kundedjnjenghmi and Kundjeyhmi dialects of Bininj Kunwok, spoken in West Arnhem Land. In other dialects, such as the Kunwinjku spoken in Gunbalanya, the tree is known as ''manbinik''. Distribution and habitat The tree dominates the closed monsoon rainforest communities along the sandstone escarpment of the western Arnhem Land Plateau. The distribution of the species appears to be limited to areas not subject to wildfire. Ecology ''Allosyncarpia'' dominated rainfo ...

Stockwellia
''Stockwellia'' is a monotypic genus in the flowering plant family Myrtaceae. The sole species in the genus, ''Stockwellia quadrifida'' (commonly known as Vic Stockwell's puzzle), is endemic to Queensland. Description ''Stockwellia quadrifida'' is a very large rainforest emergent, growing up to tall and DBH. It has straight boles with reddish-brown flaky bark and buttress roots up to high. The leaves are opposite to sub-opposite, glabrous, elliptic and leathery, measuring up to long by wide and turning red before falling. Inflorescences are axillary, produced in groups of three sessile flowers on a peduncle measuring in length. The fruits are a fused woody capsule containing oval-shaped seeds measuring up to . Discovery This species first became known to botanical science in 1971, when Atherton resident Keith Gould began experimenting with aerial photography as a means of forestry interpretation. Some of his photos appeared to show a large group of emergent tree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptopsis
''Eucalyptopsis'' is a genus of describing two species of trees, constituting part of the plant family Myrtaceae and included in the eucalypts group.

Eucalypt
Eucalypt is a descriptive name for woody plants with capsule fruiting bodies belonging to seven closely related genera (of the tribe Eucalypteae) found across Australasia: ''Eucalyptus'', '' Corymbia'', '' Angophora'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum''. Taxonomy For an example of changing historical perspectives, in 1991, largely genetic evidence indicated that some prominent ''Eucalyptus'' species were actually more closely related to ''Angophora'' than to other eucalypts; they were accordingly split off into the new genus ''Corymbia''. Although separate, all of these genera and their species are allied and it remains the standard to refer to the members of all seven genera ''Angophora'', ''Corymbia'', ''Eucalyptus'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' as "eucalypts" or as the eucalypt group. The extant genera ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' comprise six k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corymb
Corymb is a botanical term for an inflorescence with the flowers growing in such a fashion that the outermost are borne on longer pedicels than the inner, bringing all flowers up to a common level. A corymb has a flattish top with a superficial resemblance towards an umbel, and may have a branching structure similar to a panicle. Flowers in a corymb structure can either be parallel, or alternate, and form in either a convex, or flat form. Many species in the Maloideae, such as hawthorns and rowans, produce their flowers in corymbs. The Norway maple and yerba maté are also examples of corymbs. The word ''corymb'' is derived from the Ancient Greek word ''korymbos'' meaning "bunch of flowers or fruit".

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...
