Shirleya
''Shirleya'' is an extinct genus in the crape myrtle family, Lythraceae, which contains a single species, ''Shirleya grahamae''. The genus and species are known from Middle Miocene fossils found in Central Washington. History and classification The species was first described from specimens of silicified fruits preserved in chert of the "Yakima Canyon Flora". The chert was recovered from the type locality "Hi hole" site, one of the "county line hole" fossil localities of the "Yakima Canyon Flora" located north of Interstate 82 in Yakima County, Washington. The "Hi hole" site works strata was formerly thought to be part of the Museum Flow Package within the interbeds of the Sentinel Bluffs Unit of the central Columbia Plateau N2 Grande Ronde Basalt, Columbia River Basalt Group. The Museum Flow Package interbeds are dated to the middle Miocene and are approximately 15.6 million years old. Later re-evaluation of the "Hi hole" site indicated that the site is included i ...

Lythraceae
Lythraceae is a family of flowering plants, including 32 genera, with about 620 species of herbs, shrubs, and trees. The larger genera include ''Cuphea'' (275 spp.), ''Lagerstroemia'' (56), ''Nesaea'' (50), ''Rotala'' (45), and ''Lythrum'' (35). It also includes the pomegranate (''Punica granatum'', formerly in Punicaceae) and the water caltrop (''Trapa natans'', formerly in Trapaceae). Lythraceae has a worldwide distribution, with most species in the tropics, but ranging into temperate climate regions as well. The family is named after the type genus, ''Lythrum'', the loosestrifes (e.g. ''Lythrum salicaria'' purple loosestrife) and also includes henna (''Lawsonia inermis''). It now includes the pomegranate, formerly classed in a separate family Punicaceae. The family also includes the widely cultivated crape myrtle trees. Botanically, the leaves are usually in pairs (opposite), and the flower petals emerge from the rim of the calyx tube. The petals often appear crumpled. Ch ...

Middle Miocene
The Middle Miocene is a sub-epoch of the Miocene Epoch made up of two stages: the Langhian and Serravallian stages. The Middle Miocene is preceded by the Early Miocene. The sub-epoch lasted from 15.97 ± 0.05 Ma to 11.608 ± 0.005 Ma (million years ago). During this period, a sharp drop in global temperatures took place. This event is known as the Middle Miocene Climate Transition. For the purpose of establishing European Land Mammal Ages The European Land Mammal Mega Zones (abbreviation: ELMMZ, more commonly known as European land mammal ages or ELMA) are zones in rock layers that have a specific assemblage of fossils (biozones) based on occurrences of fossil assemblages of Europe ... this sub-epoch is equivalent to the Astaracian age.

Burke Museum Of Natural History And Culture
The Burke Museum of Natural History and Culture (Burke Museum) is a natural history museum in Seattle, Washington, in the United States. Established in 1899 as the Washington State Museum, it traces its origins to a high school naturalist club formed in 1879. The museum is the oldest in Washington state and boasts a collection of more than 16 million artifacts, including the world's largest collection of spread bird wings. Located on the campus of the University of Washington, the Burke Museum is the official state museum of Washington. History Young Naturalists Society The roots of the Burke Museum can be traced to a natural history club formed by high school students in the 19th century. The group was formed in December 1879 by students Edmond S. Meany, J. O. Young, P. Brooks Randolph, and Charles Denny. Denny's father, city founder Arthur Denny, was a regent of the Territorial University of Washington and arranged for the group to meet on campus. The Young Naturalists adop ...

Gynoecium
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are called ''pi ...

Dehiscent
Dehiscence is the splitting of a mature plant structure along a built-in line of weakness to release its contents. This is common among fruits, anthers and sporangia. Sometimes this involves the complete detachment of a part; structures that open in this way are said to be dehiscent. Structures that do not open in this way are called indehiscent, and rely on other mechanisms such as decay or predation to release the contents. A similar process to dehiscence occurs in some flower buds (e.g., ''Platycodon'', ''Fuchsia''), but this is rarely referred to as dehiscence unless circumscissile dehiscence is involved; anthesis is the usual term for the opening of flowers. Dehiscence may or may not involve the loss of a structure through the process of abscission. The lost structures are said to be caducous. Association with crop breeding Manipulation of dehiscence can improve crop yield since a trait that causes seed dispersal is a disadvantage for farmers whose goal is to collect ...

Sonneratia
''Sonneratia'' is a genus of plants in the family Lythraceae. Formerly the Sonneratia were placed in a family called Sonneratiaceae which included both the ''Sonneratia'' and the ''Duabanga'', but these two are now placed in their own monotypic subfamilies of the family ''Lythraceae''. The genus was also named ''Blatti'' by James Edward Smith, but ''Sonneratia'' had botanical nomenclature priority. ''Sonneratia'' species are mangrove trees. The germination is viviparous. Species The genus ''Sonneratia'' has the following species: *'' Sonneratia alba'' Sm. *'' Sonneratia apetala'' Banks *''Sonneratia caseolaris'' (L.)

Pericarp
Fruit anatomy is the plant anatomy of the internal structure of fruit. Fruits are the mature ovary or ovaries of one or more flowers. They are found in three main anatomical categories: aggregate fruits, multiple fruits, and simple fruits. Aggregate fruits are formed from a single compound flower and contain many ovaries or fruitlets. Examples include raspberries and blackberries. Multiple fruits are formed from the fused ovaries of multiple flowers or inflorescence. Examples include fig, mulberry, and pineapple. Simple fruits are formed from a single ovary and may contain one or many seeds. They can be either fleshy or dry. In fleshy fruit, during development, the pericarp (ovary wall) and other accessory structures become the fleshy portion of the fruit. The types of fleshy fruits are berries, pomes, and drupes. In some fruits, the edible portion is not derived from the ovary, but rather from the aril, such as the mangosteen or pomegranate, and the pineapple from which tissue ...

Lagerstroemia
''Lagerstroemia'' (), commonly known as crape myrtle (also spelled crepe myrtle or crêpe myrtle), is a genus of around 50 species of deciduous and evergreen trees and shrubs native to the Indian subcontinent, southeast Asia, northern Australia, and other parts of Oceania, cultivated in warmer climates around the world. It is a member of the family Lythraceae, which is also known as the loosestrife family. The genus is named after Swedish merchant Magnus von Lagerström, a director of the Swedish East India Company, who supplied Carl Linnaeus with plants he collected. These flowering trees are beautifully colored and are often planted both privately and commercially as ornamentals. Description Crape myrtles are chiefly known for their colorful and long-lasting flowers, which occur in summer. Most species of ''Lagerstroemia'' have sinewy, fluted stems and branches with a mottled appearance that arises from having bark that sheds throughout the year. The leaves are opposite and ...

Matronym
A matronymic is a personal name based on the given name of one's mother, grandmother, or any female ancestor. It is the female equivalent of a patronymic. Around the world, matronymic surnames are far less common than patronymic surnames. In some cultures in the past, matronymic last names were often given to children of unwed mothers. Or if a woman was especially well known or powerful, her descendants might adopt a matronym based on her name. A matronymic is a derived name, as compared to a matriname, which is an inherited name from a mother's side of the family, and which is unchanged. Terminology of English The word ''matronymic'' is first attested in English in 1794 and originates in the Greek μήτηρ ''mētēr'' "mother" (GEN μητρός ''mētros'' whence the combining form μητρo- ''mētro''-), ὄνυμα ''onyma'', a variant form of ὄνομα ''onoma'' "name", and the suffix -ικός -''ikos'', which was originally used to form adjectives with the sense "pe ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...
