Doryphora Viridifasciata
''Doryphora'' is a genus of 2 species of flowering plants in the family Atherospermataceae that are endemic to Australia. Plants in the genus ''Doryphora'' are medium-sized to tall trees with glabrous, leathery, sometimes serrated leaves, and flowers usually arranged in groups of 3, each flower with both make and female parts, usually 4 or 6 tepals, 6 stamens and 6 to 12 carpels. Description Plants in the genus ''Doryphora'' are medium-sized to tall trees with aromatic bark and leaves. The leaves af glabrous, leathery and sometimes deeply serrated. The flowers are bisexual, usually borne in groups of 3 in leaf axils, with large bracts covering the flower, but falling off as the flower matures. Each flower has a bell-shaped hypanthium, usually 4 or 6 tepals, six male stamens, 6 to 12 staminodes, and 6 to 12 carpels. The fruit is oval to cylindrical or urn-shaped, and splits into 2 to 4 equal valves. Taxonomy The genus ''Doryphora'' was first formally described in 1837 by Stephan ...

Doryphora (beetle)
''Doryphora'' is a genus of leaf beetles in the family Chrysomelidae. It includes nine species from Central and South America. Biology ''Doryphora'' beetles live and feed on vines of family Apocynaceae Apocynaceae (, from '' Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Notable mem .... ''Doryphora'' reproduce during the transition from the dry to the wet season. Some species are subsocial, with adult females guarding their eggs and larvae from predation. Species The genus includes the following species: * '' Doryphora aeneoornata'' Stål, 1858 * '' Doryphora bella'' Baly, 1858 * '' Doryphora bioleyi'' (Achard) * '' Doryphora centrumpunctata'' Achard, 1925 * '' Doryphora decemstillata'' Stål, 1858 * '' Doryphora diagonalis'' Stål, 1858 ** ''Doryphora diagonalis diagonalis'' Stål, 1858 ** ''Doryphora diagonalis ...

Staminode
In botany, a staminode is an often rudimentary, sterile or abortive stamen, which means that it does not produce pollen.Jackson, Benjamin, Daydon; ''A Glossary of Botanic Terms with their Derivation and Accent''; Published by Gerald Duckworth & Co. London, 4th ed 1928 Staminodes are frequently inconspicuous and stamen-like, usually occurring at the inner whorl of the flower, but are also sometimes long enough to protrude from the corolla. Sometimes, the staminodes are modified to produce nectar, as in the witch-hazel ''(Hamamelis)''.jin lu mei shu. Hamamelis Linnaeus, Sp. Pl. 1: 124. 1753. Flora of China 9: 32. 2003 Staminodes can be a critical characteristic for differentiating between species, for instance in the orchid genus ''Paphiopedilum'', and among the penstemons. In the case of cannas, the petals are inconsequential and the staminodes are refined into eye-catching petal-like replacements. A spectacular example of staminode is given by ''Couroupita guianensis ''C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacob Whitman Bailey
Jacob Whitman Bailey (1811–1857) was an American naturalist, known as the pioneer in microscopic research in America.Makers of American Botany, Harry Baker Humphrey, Ronald Press Company, Library of Congress Card Number 61-18435 Biography Jacob Whitman Bailey was born in Auburn, Massachusetts on April 29, 1811, and in 1832 graduated at West Point, where, after 1834, he was successively assistant professor, acting professor, and professor of chemistry, mineralogy, and geology. At West Point he studied with John Torrey. He devised various improvements in the construction of the microscope and made an extensive collection of microscopic objects and of algae, which he left to the Boston Society of Natural History. In 1857 he was president of the American Association for the Advancement of Science, as well as a member of the National Institute for the Promotion of Science, a precursor to the Smithsonian Institution. He was elected an Associate Fellow of the American Academy of Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Stamen
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs of a flower. Collectively, the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains sporangium, microsporangia. Most commonly, anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the Connective (botany), connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in ''Canna iridiflora'' and ''Strelitzia nicolai''. The stamens in a flower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Government
The Australian Government, also known as the Commonwealth Government or simply as the federal government, is the national executive government of Australia, a federal parliamentary constitutional monarchy. The executive consists of the prime minister, cabinet ministers and other ministers that currently have the support of a majority of the members of the House of Representatives (the lower house) and also includes the departments and other executive bodies that ministers oversee.
