Barbara Lynette Rye
Barbara Lynette Rye is an Australian botanist born in 1952. Barbara Rye has been associated with the Western Australian Herbarium, where her work as a taxonomist has been the source of many new descriptions of plants. The number of taxa recorded as described by women authors is historically very low, of the terrestrial plant species this amount is around three percent, yet in analysis published in 2019 Rye is amongst the ten most prolific women taxonomists. Born in Perth, Western Australia, she spent her childhood investigating the local flora and fauna of the Southwest Australia region, a biodiversity hotspot, and later began studies at the University of Western Australia. Barbara Rye entered the fields of zoology and botany, taking a special interest in genetics and evolutionary biology. The first description of a new species was a ''Darwinia'', a genus of the family Myrtaceae that Rye investigated for her doctoral thesis, separating '' Darwinia capitellata'' from a more widely ...

Nuytsia (journal)
''Nuytsia'' is a peer-reviewed scientific journal published by the Western Australian Herbarium. It publishes papers on systematic botany, giving preference to papers related to the flora of Western Australia. Nearly twenty percent of Western Australia's plant taxa In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and ... have been published in ''Nuytsia''. The journal was established in 1970 and has appeared irregularly since. Kevin Thiele and Juliet Wege have been in the editorial committee . ''Nuytsia'' is named after the monospecific genus ''Nuytsia'', whose only species is '' Nuytsia floribunda'', the Western Australian Christmas tree. Occasionally, the journal has published special issues, such as an issue in 2007 substantially expanding described species from Western Australia ...

Plants Described In 2022
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 ...

Flora Of Western Australia
The flora of Western Australia comprises 10,842 published native vascular plant species and a further 1,030 unpublished species. They occur within 1,543 genus, genera from 211 Family (biology), families; there are also 1,335 naturalised alien or invasive plant species more commonly known as weeds. There are an estimated 150,000 cryptogam species or nonvascular plants which include lichens, and fungi although only 1,786 species have been published, with 948 algae and 672 lichen the majority. History Indigenous Australians have a long history with the flora of Western Australia. They have for over 50,000 years obtained detailed information on most plants. The information includes its uses as sources for food, shelter, tools and medicine. As Indigenous Australians passed the knowledge along orally or by example, most of this information has been lost, along many of the names they gave the flora. It was not until Europeans started to explore Western Australia that systematic written de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Declared Rare And Priority Flora List
The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it was used extensively within the department, including the Western Australian Herbarium The Western Australian Herbarium is the state Herbarium, situated in Perth, the capital of Western Australia. It houses a collection of more than 845,000 dried specimens of plants, algae, bryophytes (mosses, liverworts and hornworts), lichens, fu .... The herbarium's journal, '' Nuytsia'', which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered. The system defines six levels of priority taxa: ;X: Threatened (Declared Rare Flora) – Presumed Extinct Taxa: These are taxa that are thought to be extinct, either because they have n ...

Mallee Bioregion
Mallee, also known as Roe Botanical District, is a biogeography, biogeographic region in southern Western Australia. Located between the Esperance Plains, Avon Wheatbelt and Coolgardie bioregions, it has a low, gently undulating topography, a semi-arid mediterranean climate, and extensive ''Eucalyptus'' mallee (habit), mallee vegetation. It has an area of . About half of the region has been cleared for intensive agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980. Geography and geology The Mallee region has a complex shape with tortuous boundaries, but may be roughly approximated as the triangular area south of a line from Bruce Rock, Western Australia, Bruce Rock to Eyre, Western Australia, Eyre, but not within 40 kilometres (25 mi) of the south coast, except at its eastern limits.

Hyden, Western Australia
Hyden is located east-southeast of Perth, Western Australia in the Shire of Kondinin. It is home to Wave Rock, Mulka's Cave and Hippos Yawn, all popular local tourist attractions. The traditional owners of the area are the Aboriginal Australian group the Njakinjaki people, who have inhabited the region for thousands of years. The many granite outcrops, land formations, waterways as well as flora and fauna are still culturally significant to them. Sandalwood cutters were thought to be the earliest European visitors in the area. The land in the surrounding area was opened up for agriculture in the 1920s. A railway line was opened between Lake Grace and Hyden Rock in April 1933. The townsite was gazetted in 1932 following demand for land around the railway terminus. The first wheat crop was harvested in Hyden in 1927. The Hyden Progress Association was established prior to 1931 when the town was home to about 100 settlers. In 1931 the town had another large wheat crop, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capsule (fruit)
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 (multicarpellary) 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 ...

Myrtaceae
Myrtaceae (), the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid ...

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 Etymology 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 (botany), 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'. The Latin ''calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet'; both words have been used interchangeably in botanical Latin. Description The term ''tepal'' is usually applied when the parts of the perianth are difficult to distinguish, e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypanthium
In angiosperms, a hypanthium or floral cup is a structure where basal portions of the Sepal, calyx, the petal, 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."Lecture 7 – Pharmacognosy and Botany (1st Semester)" ''Azerbaijan Medical University'', n.d. Accessed May 9, 2025. 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 plant identification, identification. Some geometry, geometric forms are obconic shapes, as in heteromeles, toyon (''Heteromeles''), whereas some are saucer-shaped, as in ''Mitella caulescens''. Its presence is diagnostic of many family (biology), 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 h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
