Tetratheca Pilosa
''Tetratheca pilosa'' is a flowering plant in the family Elaeocarpaceae, endemic to Australia. It is a small shrub found in dry sclerophyll forests, open heathlands and woodlands of Australia. It was first recorded in 1805 by French botanist Jacques Labillardière. Description Characterized by pink to mauve drooping (pendulous), auxiliary, solitary flowers, which are radially symmetrical, consisting of 4 sepals and 4 petals, 6 mm long. Stamens usually 8, opening by an apical pore and form a dark center to the flower above a superior ovary. Stamen tube widest between the base and the apex and are often hidden by the petals, hence the common name black eyed susan. Stems are erect, unbranched or branched from the base. Leaves are green, narrow, distinctly alternate and slightly revolute or with recurved margins. Leaves can be hairless or have non-glandular hairs. Up to 15 mm in length. ''Tetratheca'' fruit have locules that dehisce as the fruit desiccates, releasing 1 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elaeocarpaceae
Elaeaocarpaceae is a family of flowering plants. The family contains approximately 615 species of trees and shrubs in 12 genera."Elaeocarpaceae" In: Klaus Kubitzki (ed.). ''The Families and Genera of Vascular Plants'' vol. VI. Springer-Verlag: Berlin;Heidelberg, Germany. (2004). The largest genera are ''Elaeocarpus'', with about 350 species, and ''Sloanea'', with about 120. The species of Elaeocarpaceae are mostly tropical and subtropical, with a few temperate-zone species. Most species are evergreen. They are found in Madagascar, Southeast Asia, Australia, New Zealand, West Indies, and South America. Plants in this family have simple leaves, usually arranged alternately, sometimes in opposite pairs or whorled often clustered at the ends of the branches, usually with a toothed edge but sometimes reduced to scales. The flowers are arranged in leaf axils, singly or in groups and are radially symmetrical. The flowers usually have both male and female organs, four or five sepals an ...

Jacques Labillardière
Jacques-Julien Houtou de Labillardière (28 October 1755 – 8 January 1834) was a French biologist noted for his descriptions of the flora of Australia. Labillardière was a member of a voyage in search of the Jean-François de Galaup, comte de Lapérouse, La Pérouse expedition. He published a popular account of his journey and produced the first Flora (publication), Flora on the region. Early life Jacques Labillardière was born in Alençon, Normandy, France, on 28 October 1755. The ninth of 14 children of a lace merchant, he was born into a devoutly Roman Catholic family of modest means.Duyker (2003) p. 8. The surname ''Labillardière'' originated with Labillardière's grandfather, Jacques Houtou, who, in an affectation of nobility, appended the name of the family's estate, ''La Billardière'', after his surname. Labillardière was thus baptised under the surname ''Houtou de Labillardière'', but he later dropped the patronymic, retaining only ''Labillardière'' in both h ...

Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buzz Pollination
Buzz pollination or sonication is a technique used by some bees, such as solitary bees to release pollen which is more or less firmly held by the anthers. The anthers of buzz-pollinated plant species are typically tubular, with an opening at only one end, and the pollen inside is smooth-grained and firmly attached. With self-fertile plants such as tomatoes, wind may be sufficient to shake loose the pollen through pores in the anther and accomplish pollination. Visits by bees may also shake loose some pollen, but more efficient pollination of those plants is accomplished by a few insect species who specialize in sonication or buzz pollination. In order to release the pollen, solitary bees are able to grab onto the flower and move their flight muscles rapidly, causing the flower and anthers to vibrate, dislodging pollen. Pollination involving vibrations is called buzz pollination. Honeybees cannot perform buzz pollination. About 9% of the flowers of the world are primarily pollinat ...

Tetratheca
''Tetratheca'' is a genus of around 50 to 60 species of shrubs endemic to Australia. It is classified in the botanical family Elaeocarpaceae, now known to encompass the family Tremandraceae, which the genus originally belonged to. It occurs throughout extratropical Australia, and has been recorded in every mainland state except the Northern Territory. Origin and evolution The origin of the genus is thought to be south-western Western Australia, radiating eastward. The distribution of ''Tetratheca'' is mainly across the temperate southern part of the continent. Most species are localised endemics and are highly disjunct from each other. Very few are widespread across Australia; none occurs in the Nullarbor Plain and only seven are found on both the western and the south-eastern sides. (McPherson, 2008). The formation of the Nullarbor is thought to have created a barrier to dispersal between the east and west. It is estimated that the family Elaeocarpaceae is 120 million years ...

Taxa Named By Jacques Labillardière
In biology, a taxon (back-formation from ''taxonomy''; plural 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 given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
