Lasjia Erecta
''Lasjia erecta'' is a species of forest tree in the protea family that is endemic to the island of Sulawesi, Indonesia. Its closest relative is '' Lasjia hildebrandii'', also a Sulawesi endemic. History The tree was first described in 1995 as a species of ''Macadamia'', but was transferred in 2008, in a paper in the ''American Journal of Botany'' by Peter Weston and Austin Mast, to the new genus ''Lasjia''. Description The species grows to about 14 m height, with a straight trunk up to 70 cm in diameter. The leaves are consistently 4-whorled, 4–9 cm long by 1.5–4.2 cm wide. The creamy-green flowers appear in erect terminal inflorescences. The round fruits are 2.5–3 cm in diameter. Distribution and habitat The species has been recorded from the province of Southeast Sulawesi, including the adjacent island of Kabaena, as well as from Lore Lindu National Park in Central Sulawesi. It grows on ultramafic Ultramafic rocks (also referred to as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austin Mast
Austin R. Mast is a research botanist. Born in 1972, he obtained a Ph.D. from the University of Wisconsin–Madison in 2000. He is currently a professor within the Department of Biological Science at Florida State University (FSU), and has been director of FSU's Robert K. Godfrey Herbarium since August 2003. One of his main areas of research is the phylogenetics of Grevilleoideae, a subfamily of Proteaceae. In 2005 he showed the genus ''Banksia'' to be paraphyletic with respect to '' Dryandra'', Collaborating with Australian botanist Kevin Thiele, he subsequently transferred all ''Dryandra'' taxa to ''Banksia'', publishing over 120 taxonomic names in the process. The change has been adopted by the Western Australian Herbarium, although has met with some controversy. He has previously worked on the Deep South Plant Specimen Imaging Project, which created a repository of annotated high-resolution digital images of plant specimens within the East Gulf Coastal Plain The Gulf Coas ...

Southeast Sulawesi
Southeast Sulawesi ( id, Sulawesi Tenggara) is a province on the island of Sulawesi, forming the southeastern peninsula of that island, together with a number of substantial offshore islands such as Buton, Muna, Kabaena and Wawonii (formerly called Wowoni), together with many smaller islands. The capital is the city of Kendari, on the east coast of the peninsula. The province has no highway road connecting to the rest of the island, and the primary transportation link is a ferry across the Bone Gulf between Watampone (Bone) in South Sulawesi and the port of Kolaka in Southeast Sulawesi. History From the seventeenth century until the early twentieth century, the region was the site of the (Butung). Geography The two major mountain ranges in Southeast Sulawesi are the Tanggeasinua Range and the Mekongga Range. The major rivers are the Lalinda, the Lasolo, and the Sampara. Demographics The population of the province was 2,232,586 at the 2010 decennial census (1,120,2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Sulawesi
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lasjia
''Lasjia'' is a genus of five species of trees of the family Proteaceae. Three species grow naturally in northeastern Queensland, Australia and two species in Sulawesi, Indonesia. Descriptively they are the tropical or northern macadamia trees group. ''Lasjia'' species characteristically branched compound inflorescences differentiate them from the ''Macadamia'' species, of Australia, which have characteristically unbranched compound inflorescences and only grow naturally about further to the south, in southern and central eastern Queensland and in northeastern New South Wales. The Bama aboriginal Australian peoples in the late 1800s Bellenden Ker Range rainforests (north east Queensland) taught European–Australian scientists of ''L. whelanii'' trees bearing the large seeds "extensively used for food". One of those scientists, colonial botanist Frederick M. Bailey, collected and in 1889 formally published a scientific description of specimens of them under the name ''Helicia ...

Ultramafic Rock
Ultramafic rocks (also referred to as ultrabasic rocks, although the terms are not wholly equivalent) are igneous and meta-igneous rocks with a very low silica content (less than 45%), generally >18% MgO, high FeO, low potassium, and are composed of usually greater than 90% mafic minerals (dark colored, high magnesium and iron content). The Earth's mantle is composed of ultramafic rocks. Ultrabasic is a more inclusive term that includes igneous rocks with low silica content that may not be extremely enriched in Fe and Mg, such as carbonatites and ultrapotassic igneous rocks. Intrusive ultramafic rocks Intrusive ultramafic rocks are often found in large, layered ultramafic intrusions where differentiated rock types often occur in layers. Such cumulate rock types do not represent the chemistry of the magma from which they crystallized. The ultramafic intrusives include the dunites, peridotites and pyroxenites. Other rare varieties include troctolite which has a greater pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Journal Of Botany
The ''American Journal of Botany'' is a monthly peer-reviewed scientific journal which covers all aspects of plant biology. It has been published by the Botanical Society of America since 1914. The journal has an impact factor of 3.038, as of 2019. As of 2018, access is available through the publisher John Wiley & Sons ( Wiley). From 1951 to 1953, Oswald Tippo served as its editor; the current editor is Pamela Diggle. History In the early 20th century, the field of botany was rapidly expanding, but the publications in which botanists could publish remained limited and heavily backlogged. By 1905, it was estimated that 250,000 contributions were generated in 8 or 9 languages. At the 1911 annual meeting of the society in Washington D.C., it was noted that at least 300 pages of American botanical contributions were sent abroad for publication, with a backlog resulting in a one-year delay in publication. On 31 December 1907, the Botanical Society of America met in Chicago and forma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proteaceae
The Proteaceae form a family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genera with about 1,660 known species. Together with the Platanaceae and Nelumbonaceae, they make up the order Proteales. Well-known genera include '' Protea'', '' Banksia'', '' Embothrium'', '' Grevillea'', '' Hakea'' and '' Macadamia''. Species such as the New South Wales waratah ('' Telopea speciosissima''), king protea ('' Protea cynaroides''), and various species of ''Banksia'', ''soman'', and ''Leucadendron'' are popular cut flowers. The nuts of '' Macadamia integrifolia'' are widely grown commercially and consumed, as are those of Gevuina avellana on a smaller scale. Australia and South Africa have the greatest concentrations of diversity. Etymology The name Proteaceae was adapted by Robert Brown from the name Proteae coined in 1789 for the family by Antoine Laurent de Jussieu, based on the genus ''Protea'', which in 1767 Carl Linnaeus ...

Macadamia
''Macadamia'' is a genus of four species of trees in the flowering plant family Proteaceae. They are indigenous to Australia, native to northeastern New South Wales and central and southeastern Queensland specifically. Two species of the genus are commercially important for their fruit, the macadamia nut (or simply macadamia). Global production in 2015 was . Other names include Queensland nut, bush nut, maroochi nut, bauple nut and Hawaii nut. In Australian Aboriginal languages, the fruit is known by names such as ''bauple'', ''gyndl'' or ''jindilli'' (north of Great Dividing Range) and ''boombera'' (south of the Great Range). It was an important source of bushfood for the Aboriginal peoples who are the original inhabitants of the area. The nut was first commercially produced on a wide scale in Hawaii, where Australian seeds were introduced in the 1880s, and for some time, they were the world's largest producer. South Africa has been the world's largest producer of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
