Schenkia Australis
''Schenkia australis'' is a species of annual herb in the Gentianaceae family. It is endemic to Australia. Description ''Schenkia australis'' grows as an annual, or rarely biannual, herb, from 2 to 30 centimetres high. Flowers are pink, red or yellow. Taxonomy This species was first published by Robert Brown in his 1810 ''Prodromus florae Novae Hollandiae'', under the name ''Erythraea australis''. In 1917 the name it was transferred into ''Centaurium'' as ''C. australe'' by George Claridge Druce, on the grounds that ''Erythraea'' was an illegitimate later synonym of ''Centaurium''. In 1928 Karel Domin resurrected ''Erythraea'', transferring this species back into it, but at the same time demoting it to a variety of ''Erythraea spicata'' (now '' Schenkia spicata''). Eventually it was restored to ''Centaurium'' for a second time. In 1996, it was decided that ''Centaurium australis'' could not be differentiated from ''Centaurium spicatum'' (now ''Schenkia spicata''), and the ...

Schenkia Sebaeoides
''Schenkia sebaeoides'', known as Āwiwi in Hawaiian language, Hawaiian and lavaslope centaury in English language, English, is a rare species of flowering plant. It is Endemism, endemic to Hawaiian tropical low shrublands, low shrublands in the state of Hawaii, Hawaii in the United States. It is present on the islands of Kauai, Oahu, Lanai, Molokai, and Maui. At the time it was added to the endangered Species Act, endangered species list of the United States in 1991 it was known from seven populations for a total of fewer than 1000 individuals.USFWS''Centaurium sebaeoides'' Five Year Review.August 27, 2010. It is threatened by habitat loss. Until 2004 it was a member of genus ''Centaurium''; it and several other species have since been transferred to other genera. This is the only plant in the Gentiana, gentian family, Gentianaceae, that is native to Hawaii. This is an annual herb, one of only 3% of Hawaiian flora that have annual plant, annual life cycles. It often bears white ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schenkia Spicata
''Schenkia spicata'' is a species of annual herb in the family Gentianaceae. It has a very wide old world distribution, ranging from north Africa, through Europe and into Asia. It was first published as ''Gentiana spicata'' by Carl Linnaeus in his 1753 ''Species plantarum''. It was later transferred into ''Erythraea'' and then ''Centaurium'', under a broad circumscription of the latter genus that was subsequently found to be polyphyletic. In 2004 ''Centaurium'' was split into four genera, with ''C. spicatum'' becoming ''Schenkia spicata''. At the same time, it was noted that European and Australian specimens ascribed to this species are in fact different taxa; for example, all Australian specimens studied were tetraploid, whereas all European specimens studied were diploid. Therefore, the Australian specimens were segregated into a new species, ''Schenkia australis ''Schenkia australis'' is a species of annual herb in the Gentianaceae family.

Centaurium
''Centaurium'' (centaury) is a genus of 20 species in the gentian family (Gentianaceae), tribe Chironieae, subtribe Chironiinae. The genus was named after the centaur Chiron, famed in Greek mythology for his skill in medicinal herbs. It is distributed across Europe and into Asia. Until 2004, ''Centaurium'' was given a much wider circumscription, comprising about 50 species ranging across Europe, Asia, the Americas, Australasia and the Pacific. However this circumscription was polyphyletic, so in 2004 the genus was split in four, being ''Centaurium'' sensu stricto, ''Zeltnera'', ''Gyrandra'' and '' Schenkia''.

Gentianaceae
Gentianaceae is a family of flowering plants of 103 genera and about 1600 species. Etymology The family takes its name from the genus '' Gentiana'', named after the Illyrian king Gentius. Distribution Distribution is cosmopolitan. Characteristics The family consists of trees, shrubs and herbs showing a wide range of colours and floral patterns. Flowers are actinomorphic and bisexual with fused sepals and petals. The stamens are attached to the inside of the petals ( epipetalous) and alternate with the corolla lobes. There is a glandular disk at the base of the gynoecium, and flowers have parietal placentation. The inflorescence is cymose, with simple or complex cymes. The fruits are dehiscent septicidal capsules splitting into two halves, rarely some species have a berry. Seeds are small with copiously oily endosperms and a straight embryo. The habit varies from small trees, pachycaul shrubs to (usually) herbs, with ascending, erect or twining stems. Plants are usually ...

August Grisebach
August Heinrich Rudolf Grisebach () was a German botany, botanist and phytogeography, phytogeographer. He was born in Hannover on 17 April 1814 and died in Göttingen on 9 May 1879. Biography Grisebach studied at the Lyceum in Hanover, the cloister-school at Ilfeld, and the University of Göttingen. He graduated in medicine from the University of Berlin (other), University of Berlin in 1836. He undertook expeditions to Provence, Turkey, the Balkans, and Norway. In 1837 he became associate professor and in 1847 full professor at the medical faculty in Göttingen and was named director of Old Botanical Garden of Göttingen University, the botanical garden there in 1875. While his main fields of interest were phytogeography and systematics, especially the Gentianaceae and Malpighiaceae, he considered his ''Flora of the British West Indian Islands'' his most important work. Much of his collection, especially the Type (biology), types of species described by him, are housed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...

Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protected ...
