Agonis
''Agonis'' is a genus of flowering plants in the plant family Myrtaceae. All are endemic to Western Australia, growing near the coast in the south west. Plants in the genus ''Agonis'' are shrubs or trees with bisexual flowers arranged in heads in leaf axils with 5 sepals and usually 5 white petals, each with 15 to 30 stamens arranged opposite the sepals, and the fruit a woody capsule. Description Plants in the genus ''Agonis'' are shrubs or trees, the leaves simple with small glands. The flowers are bisexual with a pair of bracteoles and a bract at the base. The flowers have a leathery floral tube, 5 egg-shaped or triangular sepals, 5 white petals and 15 to 30 stamens in a single whorl with 6 or 7 stamens opposite the sepals and none opposite the petals. The ovary is inferior with the style in a depression at the top of the ovary, and the fruit is a woody capsule with winged seeds.

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 ...

Robert Sweet (botanist)
Robert Sweet (1783–20 January 1835) was an English botanist, horticulturist and ornithologist. Born at Cockington near Torquay, Devonshire, England in 1783, Sweet worked as a gardener from the age of sixteen, and became foreman or partner in a series of nurseries. He was associated with nurseries at Stockwell, Fulham and Chelsea. In 1812 he joined Colvills, the famous Chelsea nursery, and was elected a fellow of the Linnean Society. By 1818 he was publishing horticultural and botanical works. Sweet published a number of illustrated works on plants cultivated in British gardens and hothouses. The plates were mainly drawn by Edwin Dalton Smith (1800–1883), a botanical artist, who was attached to the Royal Botanic Gardens, Kew. His works include ''Hortus Suburbanus Londinensis'' (1818), ''Geraniaceae'' (five volumes) (1820–30), ''Cistineae'', ''Sweet's Hortus Britannicus'' (1826–27), '' Flora Australasica'' (1827–28) and ''British Botany'' (with H. Weddell) (1831). H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

George Don
George Don (29 April 1798 – 25 February 1856) was a Scottish botanist and plant collector. Life and career George Don was born at Doo Hillock, Forfar, Angus, Scotland on 29 April 1798 to Caroline Clementina Stuart and George Don (b.1756), principal gardener of the Royal Botanic Garden Edinburgh in 1802. Don was the elder brother of David Don, also a botanist. He became foreman of the gardens at Chelsea in 1816. In 1821, he was sent to Brazil, the West Indies and Sierra Leone to collect specimens for the Royal Horticultural Society.

Don's main work was his four volume ''A General System of Gardening and Botany'', published between 1832 and 1838 (often referred to as Gen. Hist., an abbreviation of the alternative title: ''A General History of the Dichlamydeous Plants''). He revised the first supplement to Loudon's ''Encyclopaedia of Plants'', and provided a ...
