Eucalyptus Pyrenea
''Eucalyptus pyrenea'', commonly known as Pyrenees gum, is a species of tree that is endemic to Victoria, Australia. It has smooth, greyish bark with rough, fibrous bark on the lower part of the trunk, lance-shaped to curved adult leaves, flower buds in groups of seven, white flowers and cup-shaped fruit. Description ''Eucalyptus pyrenea'' is a slender tree that typically grows to a height of and forms a lignotuber. It has smooth, greyish bark with some rough, fibrous or flaky bark near the base. Young plants and coppice regrowth have dull, bluish green leaves that are slightly paler on the lower surface, egg-shaped to elliptical, long and wide. Adult leaves are the same shade of shiny green on both sides, lance-shaped to curved, long and wide on a petiole long. The flower buds are arranged in leaf axils in groups of seven on a thin, flattened, unbranched peduncle long, the individual buds on pedicels long. Mature buds are oval to cylindrical, long and wide with a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kevin James Rule
Kevin James Rule was born at Daylesford, Victoria on 9 November 1941. He was a secondary school teacher and had a particular interest in the taxonomy of Australian eucalyptus. He discovered several new species in Victoria. He is an honorary associate of the Royal Botanic Gardens Victoria. His main field is in taxonomy, particularly eucalypts and as a botanical collector. In 2011 Kevin James Rule described three sub-species of ''Eucalyptus baueriana ''Eucalyptus baueriana'', commonly known as blue box or round-leaved box, is a tree that is endemic to south-eastern Australia.

Capsule (botany)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classifie ...

Myrtales Of Australia
The Myrtales are an order of flowering plants placed as a sister to the eurosids II clade as of the publishing of the ''Eucalyptus grandis'' genome in June 2014. The APG III system of classification for angiosperms still places it within the eurosids. This finding is corroborated by the placement of the Myrtales in the Malvid clade by the One Thousand Plant Transcriptomes Initiative. The following families are included as of APGIII: * Alzateaceae S. A. Graham * Combretaceae R. Br. ( leadwood family) * Crypteroniaceae A. DC. * Lythraceae J. St.-Hil. ( loosestrife and pomegranate family) * Melastomataceae Juss. (including Memecylaceae DC.) * Myrtaceae Juss. (myrtle family; including Heteropyxidaceae Engl. & Gilg, Psiloxylaceae Croizat) * Onagraceae Juss. (evening primrose and Fuchsia family) * Penaeaceae Sweet ex Guill. (including Oliniaceae Arn., Rhynchocalycaceae L. A. S. Johnson & B. G. Briggs) * Vochysiaceae A. St.-Hil. The Cronquist system gives essentially the same co ...

Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grow ...

Trees Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 30,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (''Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae ('' Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the ...

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 ...

Pyrenees (Victoria)
The Pyrenees is a wine-producing region centred on the Pyrenees ranges located in Victoria, Australia near the town of Avoca. The Pyrenees Ranges are at the southern end of The Great Dividing Range with altitudes ranging from 300 to over 750 m (approximately 980–2460 ft). Main peaks in the range include Mount Avoca (747 m) and Mount Warrenmang (537 m). Exploration The explorer and surveyor Thomas Mitchell was the first European recorded to have travelled through the district on his 1836 journey of exploration. The ranges reminded him of the Pyrenees in Europe where he had served as an army officer, hence the name he gave them. He found the area more temperate in climate and better watered than inland New South Wales, and he encouraged settlers to take up land in the region he described as "Australia Felix". Wine Vines were first planted in the region in 1858. Several wine growers produced and sold wine in the region in the late 1800s and early part of the twe ...

Hypanthium
In angiosperms, a hypanthium or floral cup is a structure where basal portions of the calyx, the corolla, and the stamens form a cup-shaped tube. It is sometimes called a floral tube, a term that is also used for corolla tube and calyx tube. It often contains the nectaries of the plant. It is present in many plant families, although varies in structural dimensions and appearance. This differentiation between the hypanthium in particular species is useful for identification. Some geometric forms are obconic shapes as in toyon, whereas some are saucer-shaped as in '' Mitella caulescens''. Its presence is diagnostic of many families, including the Rosaceae, Grossulariaceae, and Fabaceae. In some cases, it can be so deep, with such a narrow top, that the flower can appear to have an inferior ovary - the ovary is below the other attached floral parts. The hypanthium is known by different common names in differing species. In the eucalypts, it is referred to as the ''gum nut''; ...

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] |
Operculum (botany)
In botany, an operculum () or calyptra () is a cap-like structure in some flowering plants, mosses, and fungus, fungi. It is a covering, hood or lid, describing a feature in plant morphology. Flowering plants In flowering plants, the operculum, also known as a calyptra, is the cap-like covering or "lid" of the flower or fruit that detaches at maturity. The operculum is formed by the fusion of sepals and/or petals and is usually shed as a single structure as the flower or fruit matures. The name is also used for the capping tissue of roots, the root cap. In eucalypts, (including ''Eucalyptus'' and ''Corymbia'' but not ''Angophora'') there may be two opercula - an outer operculum formed by the fusion of the united sepals and an inner operculum formed by the fusion of the sepals. In that case, the outer operculum is shed early in the development of the bud leaving a scar around the bud. In those species that lack an outer operculum, there is no bud scar. The inner operculum is sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedicel (botany)
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts. In cultivation In Halloween types of pumpkin or squash plants, the shape of the pedicel has received particular attention because plant breeders are trying to optimize the size and shape of the pedicel for the best "lid" for a "jack-o'-lantern".
