Semecarpus Magnificus
''Semecarpus magnificus'' is a species of plant in the family Anacardiaceae. It is endemic to New Guinea. Description According to the original describer Karl Schumann, ''Semecarpus magnificus'' is a tree growing to 4–6 m tall. Its leaves are 0.7–1.2 m long and 10.5–20 cm wide near the tip. They are crowded together at the ends of the branches, as in '' Clavija'', '' Theophrasta'' and other similar genera. Schumann only had access to male flowers. They are grouped in inflorescences 60–80 cm long, that are composed of distant branches laden with flower clusters. The calyx is about 1 mm long. The petals are 3 mm long, the stamens 4 mm. The rudimentary ovary is about 1 mm long. The fruit is about 3 cm long, including the hypocarpium, and 2.5 cm across. Taxonomy ''Semecarpus magnificus'' was first described by Karl Schumann in 1889, based on a collection by Max Hollrung made during a research expedition to New Guinea ...

Karl Moritz Schumann
Karl Moritz Schumann (17 June 1851 – 22 March 1904) was a German botanist. Schumann was born in Görlitz. He was curator of the Botanisches Museum in Berlin-Dahlem from 1880 until 1894. He also served as the first chairman of the ''Deutsche Kakteen-Gesellschaft'' (German Cactus Society) which he founded on 6 November 1892. He died in Berlin. Karl Moritz Schumann participated as a collaborator in ''Die Natürlichen Pflanzenfamilien'' by Adolf Engler and K. A. E. Prantl and in ''Flora Brasiliensis'' by Carl Friedrich Philipp von Martius. The genera '' Schumannianthus'' ( Gagnepain), '' Schumanniophyton'' ( Harms), '' Schumannia'' (Kuntze Kuntze is a surname of German origin.

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ 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 and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the 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 stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Semecarpus
''Semecarpus'' is a genus of plants in the family Anacardiaceae. Taxonomy The genus ''Semecarpus'' was erected by Carl Linnaeus the Younger in 1782 in ''Supplementum Plantarum''. In the same work, he described '' Semecarpus anacardium''. The gender of the genus name has been the subject of some confusion. Early authors treated it as feminine. As one example, in 1850, Carl Ludwig Blume described a number of species of ''Semecarpus'', such as ''Semecarpus heterophylla'' and ''Semecarpus longifolia'', using feminine endings for the specific epithet. However, Example 3 of Article 62 of the ''International Code of Nomenclature for algae, fungi, and plants'' states that all compounds ending in the Greek masculine ''‑carpos'' or ''‑carpus'' are masculine. , the International Plant Names Index and Plants of the World Online used masculine endings, such as ''Semecarpus heterophyllus'' and ''Semecarpus longifolius'', while the Global Biodiversity Information Facility had mixed end ...

Kaiser-Wilhelmsland
Kaiser-Wilhelmsland ("Emperor William's Land") formed part of German New Guinea (german: Deutsch-Neuguinea), the South Pacific protectorate of the German Empire. Named in honour of Wilhelm I, who reigned as German Emperor () from 1871 to 1888, it included the northern part of present-day Papua New Guinea. From 1884 until 1920 the territory was a protectorate ( de , Schutzgebiet) of the German Empire. Kaiser-Wilhelmsland, the Bismarck Archipelago (including New Mecklenburg and New Pomerania), the northern Solomon Islands, the Caroline Islands, Palau, Nauru, the Northern Mariana Islands, and the Marshall Islands comprised German New Guinea. Most of the German settlers in Kaiser-Wilhelmsland worked as plantation owners, miners, or government functionaries; the number of European settlers, including non-Germans, was never very high. In 1885, Lutheran and Catholic congregations sent clergy to establish missions; they experienced moderate, but very slow, success with the indigenous ...

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Udo Max Hollrung
Max Hollrung (born 25 October 1858 in Hosterwitz, Dresden, died 5 May 1937 in Halle (Saale)) was a German botanist, and an early specialist in phytopathology. He was the first university teacher in Germany to be appointed to teach on the subject of plant diseases and plant protection at a university. Life and work Hollrung was the son of a master mason. He studied natural sciences, in particular, chemistry, acquiring his doctorate from the University of Leipzig in 1882. After a three-year assistantship at the Agriculture-Chemical Experimental Station in Halle (Saale), he participated in a research expedition to New Guinea from 1886 to 1888. At his return, Julius Kühn transferred him to the Agricultural Institute of the University of Halle, to work in the newly established Research Center for Nematode Control. From 1898 Hollrung was head of the experimental station for crop protection of the Chamber of Agriculture of the province of Saxony in Halle / Saale. From 1898, he was ...

Ovary (botany)
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. Fruits A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm. Because gymnosperms do not have an ovary but reproduce through double fertilization of unprotected ovules, they produce naked seeds that do not ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...
