Degeneriaceae
''Degeneria'' is a genus of flowering plants endemic to Fiji. It is the only genus in the family Degeneriaceae. The APG IV system of 2016 (unchanged from the APG system of 1998, the APG II system of 2003 and the APG III system of 2009), recognizes this family, and assigns it to the order Magnoliales in the clade magnoliids. ''Degeneria'' was named after Otto Degener, who first found ''D. vitiensis'' in 1942. Classical studies of native stands of ''Degeneria'' from Vanua Levu and Viti Levu islands were conducted more than 30 years ago. A 45-cent stamp issued in 1988 depicted a flowering branch of ''Degeneria vitiensis.'' This species appears on Fiji's five-dollar bill. A one-dollar 1988 philatelic commemorated the discovery of ''Degeneria roseiflora'' earlier in that same year. The genus contains two species of trees, both native to Fiji: * '' Degeneria roseiflora'' John M.Mill. – Vanua Levu, Taveuni – karawa * '' Degeneria vitiensis'' L.W.Bailey & A.C.Sm. – Viti Levu ...

Magnoliales
The Magnoliales are an order of flowering plants. Classification The Magnoliales include six families: * Annonaceae (custard apple family, over 2000 species of trees, shrubs, and lianas; mostly tropical but some temperate) * Degeneriaceae (two species of trees found on Pacific islands) * Eupomatiaceae (two species of trees and shrubs found in New Guinea and eastern Australia) * Himantandraceae (two species of trees and shrubs, found in tropical areas in Southeast Asia and Australia) * Magnoliaceae (about 225 species including magnolias and tulip trees) * Myristicaceae (several hundred species including nutmeg) APG system The APG system (1998), APG II system (2003), APG III system (2009), and APG IV system (2016) place this order in the clade magnoliids, circumscribed as follows: In these systems, published by the APG, the Magnoliales are a basal group, excluded from the eudicots. Earlier systems The Cronquist system (1981) placed the order in the subclass Magnoliidae o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fijian Dollar
The Fijian dollar (currency sign: FJ$, $; currency code: FJD) has been the currency of Fiji since 1969 and was also the currency between 1867 and 1873. It is normally abbreviated with the dollar sign $, or alternatively FJ$ to distinguish it from other dollar-denominated currencies. It is divided into 100 cents. History Decimalisation origins Fiji followed the pattern of South Africa, Australia, and New Zealand in that when it adopted the decimal system, it decided to use the half pound unit as opposed to the pound unit of account. The choice of the name dollar was motivated by the fact that the reduced value of the new unit corresponded more closely to the value of the US dollar than it did to the pound sterling. Second dollar (1969–present) The dollar was reintroduced on 15 January 1969, replacing the Fijian pound at a rate of 1 pound = 2 dollars, or 10 shillings = FJ$1. Despite Fiji having been a republic since 1987, coins and banknotes continued to feature Queen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gynoecium
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are cal ...

Galbulimima
''Galbulimima'' is a genus of flowering plants and the sole genus of the family Himantandraceae. Members of the family are found in the tropical zones of eastern Malaysia, the Moluccas, the Celebes, New Guinea, northern Australia and the Solomon Islands. Being classified in the magnoliids, this family is part of neither the monocots nor the eudicots and is related to families such as the Annonaceae, the Degeneriaceae, the Eupomatiaceae and the Magnoliaceae The Magnoliaceae () are a flowering plant family, the magnolia family, in the order Magnoliales. It consists of two genera: ''Magnolia'' and '' Liriodendron'' (tulip trees). Unlike most angiosperms, whose flower parts are in whorls (rings), t .... The genus comprises from 1 to 3 species, according to different authorities, including '' Galbulimima belgraveana.'' References Magnoliales Magnoliales genera {{Magnoliales-stub ...

APG IV System
The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG). It was published in 2016, seven years after its predecessor the APG III system was published in 2009, and 18 years after the first APG system was published in 1998. In 2009, a linear arrangement of the system was published separately; the APG IV paper includes such an arrangement, cross-referenced to the 2009 one. Compared to the APG III system, the APG IV system recognizes five new orders (Boraginales, Dilleniales, Icacinales, Metteniusales and Vahliales), along with some new families, making a total of 64 angiosperm orders and 416 families. In general, the authors describe their philosophy as "conservative", based on making changes from APG III only where "a well-supported need" has been demonstrated. This has sometimes resulted in placements that ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
APG System
The APG system (Angiosperm Phylogeny Group system) of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy. Published in 1998 by the Angiosperm Phylogeny Group, it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016. History The original APG system is unusual in being based, not on total evidence, but on the cladistic analysis of the DNA sequences of three genes, two chloroplast genes and one gene coding for ribosomes. Although based on molecular evidence only, its constituent groups prove to be supported by other evidence as well, for example pollen morphology supports the split between the eudicots and the rest of the former dicotyledons. The system is rather controversial in its decisions at the family level, splitting a number of long-established families and submerging some other families. It also is unusual in not using botanical names above the level of order, that is, an orde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
APG III System
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families follo ...

Irving Widmer Bailey
Irving Widmer Bailey (August 15, 1884 – May 16, 1967) was an American botanist known for his work in plant anatomy. Early life and education Bailey was born in 1884, in Tilton, New Hampshire to Ruth Pouter Bailey and Solon Irving Bailey. His father was a professor of astronomy at Harvard University. In 1907 Bailey graduated from Harvard College, and two years later received his master's degree in forestry from Harvard's Graduate School of Applied Sciences. Scientific career In 1909, Bailey took a job as instructor of forestry at Harvard's Graduate School of Applied Sciences. He went on to work at the Bussey Institution, which later became a division of Harvard's Graduate School of Applied Biology, and also held positions at the Arnold Arboretum and Gray Herbarium, both of which were divisions of Harvard University Herbaria. In 1943, botanist R.A.Howard named a genus of flowering plants from Australia, (belonging to the family Stemonuraceae) as ''Irvingbaileya'' in his honou ...

Taveuni
Taveuni (pronounced ) is the third-largest island in Fiji, after Viti Levu and Vanua Levu, with a total land area of . The cigar-shaped island, a massive shield volcano which rises from the floor of the Pacific Ocean, is situated to the east of Vanua Levu, across the Somosomo Strait. It belongs to the Vanua Levu Group of islands and is part of Fiji's Cakaudrove Province within the Northern Division. The island had a population of around 19,000, some 75 per cent of them indigenous Fijians, at the 2015 census. Taveuni has abundant flora and is known as the 'Garden Island of Fiji'. It is a popular tourist destination. Tourists are attracted to the excellent diving opportunities, prolific bird life, bushwalks and waterfalls. Central parts of the island receive very high rainfall rates. Being volcanic in origin Taveuni's soils have supported the island's most historically significant industry, agriculture. Geography Taveuni is located at the northern end of the Koro Sea, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ovule
In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the '' integument'', forming its outer layer, the ''nucellus'' (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center. The female gametophyte — specifically termed a ''megagametophyte''— is also called the ''embryo sac'' in angiosperms. The megagametophyte produces an egg cell for the purpose of fertilization. The ovule is a small structure present in the ovary. It is attached to the placenta by a stalk called a funicle. The funicle provides nourishment to the ovule. Location within the plant In flowering plants, the ovule is located inside the portion of the flower called the gynoecium. The ovary of the gynoecium produces one or more ovules and ultimately becomes the fruit wall. Ovules are attached to the placenta in the ovary through a stalk-like structure known as a ''funiculus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winteraceae
Winteraceae is a primitive family of tropical trees and shrubs including 93 species in five genera. It is of particular interest because it is such a primitive angiosperm family, distantly related to Magnoliaceae, though it has a much more southern distribution. Plants in this family grow mostly in the southern hemisphere, and have been found in tropical to temperate climate regions of Malesia, Oceania, eastern Australia, New Zealand, Madagascar and the Neotropics, with most of the genera concentrated in Australasia and Malesia. The five genera, ''Takhtajania, Tasmannia, Drimys, Pseudowintera'', and ''Zygogynum s.l.'' all have distinct geographic extant populations. '' Takhtajania'' includes a single species, ''T. perrieri'', endemic only to Madagascar, '' Tasmannia'' has the largest distribution of genera in Winteraceae with species across the Philippines, Borneo, New Guinea, Eastern Australia, and Tasmannia, '' Drimys'' is found in the Neotropical realm, from southern Mexi ...
