Sisymbrium Erysimoides
''Sisymbrium erysimoides'', known as smooth mustard, is a plant in the family Brassicaceae. It is found on roadsides and wasteland, and as a weed of arable land. A native to western Mediterranean region, it is now well-established throughout the world. Description Cool season annual, erect, glabrous or shortly pubescent herb 10–80 cm tall. Basal leaves are to 15 cm long, lyrate-pinnatifid, toothed, petiolate, reducing to lanceolate, mostly toothed. Flowerheads are paniculate. Sepals are 1–2 mm long and glabrous. Petal Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usuall ...s are 1–2.5 mm long, yellow to pale yellow. Siliqua are linear, straight, horizontal, 2.5–5 cm long, 1 mm wide and attenuate into a style; pedicels are thick and 2–5 mm long. Flowering is in late winte ...

Timothy John Entwisle
Timothy John Entwisle (born 1960), is an Australian botanist, much of whose research work is in phycology (algae). See for example the articles. He was awarded a Ph.D. from La Trobe University in 1986 for work on the taxonomy of ''Vaucheria''. He was New South Wales’ Government Botanist in 2007 and 2008, and for eight years was the executive director of the Royal Botanic Gardens Sydney (2003–2011). Subsequently, he was director of Conservation, Living Collections and Estates, Kew, London from 2011, and since 2013 he has been director of the Royal Botanic Gardens Victoria. He is an honorary professorial fellow at the University of Melbourne and is currently (2020) president of the International Association of Botanic Gardens. As director of the Royal Botanic Gardens Sydney, Entwisle managed Sydney's Royal Botanic Gardens, the Mount Tomah Botanic Garden, in the Blue Mountains and the Mount Annan Botanic Garden, near Camden, and at Kew, he was responsible for Kew Gardens, ...

Brassicaceae
Brassicaceae () or (the older) Cruciferae () is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are ''Draba'' (440 species), ''Erysimum'' (261 species), ''Lepidium'' (234 species), ''Cardamine'' (233 species), and ''Alyssum'' (207 species). The family contains the cruciferous vegetables, including species such as ''Brassica oleracea'' (cultivated as cabbage, kale, cauliflower, broccoli and collards), ...

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 ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Siliqua
The siliqua (plural ''siliquae'') is the modern name given (without any ancient evidence to confirm the designation) to small, thin, Roman silver coins produced in the 4th century A.D. and later. When the coins were in circulation, the Latin word ''siliqua'' was a unit, perhaps of weight defined by one late Roman writer as one twenty-fourth of a Roman solidus. The term siliqua comes from the ''siliqua graeca'', the seed of the carob tree, which in the Roman weight system is equivalent to of a scruple ( of a Roman pound or about 0.19 grams). The term has been applied in modern times to various silver coins on the premise that the coins were valued at of the gold solidus (which weighed of a Roman pound) and therefore represented a siliqua of gold in value. Since gold was worth about 12 times as much as silver in ancient Rome (in Diocletian's ''Edict of Maxmimum Prices'' of 301),Bransbourg, Giles. "Inflation and monetary reforms in the fourth century: Diocletian's twin Edicts ... [...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".

Tablelands Region
The Tablelands Region is a local government area in Far North Queensland, Australia inland from the city of Cairns. Established in 2008, it was preceded by four previous local government areas which dated back more than a century. On 1 January 2014, one of those local government areas, the Shire of Mareeba, was re-established independent of the Tablelands Region. It has an estimated operating budget of A$62.2 million. History '' Yidinji'' (also known as ''Yidinj'', ''Yidiny'', and ''Idindji'') is an Australian Aboriginal language. Its traditional language region is within the local government areas of Cairns Region and Tablelands Region, in such localities as Cairns, Gordonvale, and the Mulgrave River, and the southern part of the Atherton Tableland including Atherton and Kairi. Prior to the 2008 amalgamation, the Tablelands Region consisted the entire area of four previous local government areas: * the Shire of Atherton; * the Shire of Eacham; * the Shire of Herberton; a ...
