Klamath Coneflower
''Rudbeckia'' () is a plant genus in the Asteraceae or composite family. Rudbeckia flowers feature a prominent, raised central disc in black, brown shades of green, and in-between tones, giving rise to their familiar common names of coneflowers and black-eyed-susans. All are native to North America, and many species are cultivated in gardens for their showy yellow or gold flower heads that bloom in mid to late summer. The species are herbaceous, mostly perennial plants (some annual or biennial) growing to 0.5–3.0 m tall, with simple or branched stems. The leaves are spirally arranged, entire to deeply lobed, and 5–25 cm long. The flowers are produced in daisy-like inflorescences, with yellow or orange florets arranged in a prominent, cone-shaped head; "cone-shaped" because the ray florets tend to point out and down (are decumbent) as the flower head opens. A large number of species have been proposed within ''Rudbeckia'', but most are now regarded as synonyms of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudbeckia Hirta
''Rudbeckia hirta'', commonly called black-eyed Susan, is a North American flowering plant in the family Asteraceae, native plant, native to Eastern and Central North America and naturalized in the Western part of the continent as well as in China. It has now been found in all 10 Canadian Provinces and all 48 of the states in the contiguous United States. ''Rudbeckia hirta'' is the state flower of Maryland. Description ''Rudbeckia hirta'' is an upright annual plant, annual (sometimes biennial plant, biennial or perennial plant, perennial) growing tall by wide. It has alternate, mostly basal leaf, leaves 10–18 cm long, covered by coarse hair, with stout branching stems and daisy-like, pseudanthium, composite flower heads appearing in late summer and early autumn. In the species, the flowers are up to in diameter, with yellow ray florets circling conspicuous brown or black, dome-shaped cone of many small disc florets. However, extensive breeding has produced a range of si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Natural Philosophy
Natural philosophy or philosophy of nature (from Latin ''philosophia naturalis'') is the philosophical study of physics Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which r ..., that is, nature and the physical universe. It was dominant before the development of modern science. From the ancient world (at least since Aristotle) until the 19th century, ''natural philosophy'' was the common term for the study of physics (nature), a broad term that included botany, zoology, anthropology, and chemistry as well as what we now call physics. It was in the 19th century that the concept of science received its modern shape, with different subjects within science emerging, such as astronomy, biology, and physics. Institutions and communities devoted to science were founded. Isaac Newton's book ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olof Rudbeck The Elder
Olaus Rudbeck (also known as Olof Rudbeck the Elder, to distinguish him from his son, and occasionally with the surname Latinized as ''Olaus Rudbeckius'') (13 September 1630 – 12 December 1702) was a Swedish scientist and writer, professor of medicine at Uppsala University, and for several periods ''rector magnificus'' of the same university. He was born in Västerås, the son of Bishop Johannes Rudbeckius, who was personal chaplain to King Gustavus Adolphus, and the father of botanist Olof Rudbeck the Younger. Rudbeck is primarily known for his contributions in two fields: human anatomy and linguistics, but he was also accomplished in many other fields including music and botany. He established the first botanical garden in Sweden at Uppsala, called Rudbeck's Garden, but which was renamed a hundred years later for his son's student, the botanist Carl Linnaeus. Human anatomy Rudbeck was one of the pioneers in the study of lymphatic vessels. According to his supporters in Swe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olof Rudbeck The Younger
Olof Rudbeck the Younger or Olaus Rudbeckius d.y. (15 March 1660 – 23 March 1740) was a Swedish explorer, scientist, botanist, ornithologist and rector of Uppsala University. Biography Olof Rudbeck was born in Uppsala, Sweden, the son of Olaus Rudbeck Sr. (1630–1702), a professor of medicine at Uppsala University. He travelled to England, Holland and Germany in 1687 to study botany. Rudbeck took a medical degree at the Utrecht University in 1690. Returning to his home country in 1692, he succeeded his father as professor of medicine at Uppsala University. Serving alongside Lars Roberg (1664–1742), he specialized in anatomy, botany, zoology, and pharmacology, while Roberg gave lectures in medicine, surgery, physiology and chemistry. He travelled to Lapland in 1695, joining an expedition commissioned by the King Charles XI of Sweden (1655–1697), for which his mission was to study nature, the mountainous region in particular. He returned and published ''Lapponia illustrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uppsala University
Uppsala University ( sv, Uppsala universitet) is a public university, public research university in Uppsala, Sweden. Founded in 1477, it is the List of universities in Sweden, oldest university in Sweden and the Nordic countries still in operation. The university rose to significance during the rise of Swedish Empire, Sweden as a great power at the end of the 16th century and was then given a relative financial stability with a large donation from King Gustavus Adolphus of Sweden, Gustavus Adolphus in the early 17th century. Uppsala also has an important historical place in Swedish national culture, identity and for the Swedish establishment: in historiography, literature, politics, and music. Many aspects of Swedish academic culture in general, such as the white student cap, originated in Uppsala. It shares some peculiarities, such as the student nation system, with Lund University and the University of Helsinki. Uppsala belongs to the Coimbra Group of European universities a ...

Carolus Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In ...

Dot Moth
The dot moth (''Melanchra persicariae'') is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in 1761. It is a very distinctive species with very dark brown, almost black, forewings marked with a large white stigma from which the species gets its common name. The hindwings are grey with a dark band at the termen. The wingspan is 38–50 mm. It flies at night in July and August and is attracted to light, sugar and flowers. Distribution The distribution area ranges from Spain in the west to Korea and Japan. It is found throughout Europe apart from the south-east. To the north it is found in Scotland and southern Fennoscandia, east through southern Russia, the Russian Far East and Siberia and Central Asia to the Kamchatka Peninsula. Then northern China to Korea and Japan. The southern boundary runs through northern Spain, Italy (except for Sicily), Macedonia, Bulgaria, Asia Minor, the southern Caucasus, northern Iran. In the Alps it rises u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cabbage Moth
The cabbage moth (''Mamestra brassicae'') is primarily known as a pest that is responsible for severe crop damage of a wide variety of plant species. The common name, cabbage moth, is a misnomer as the species feeds on many fruits, vegetables, and crops in the genus ''Brassica'' (i.e. cabbage, broccoli, Brussels sprouts). Other notable host plants include tobacco, sunflower, and tomato, making this pest species particularly economically damaging. The moth spans a wide geographic range encompassing the entire Palearctic region. Due to this wide geographic region and the presence of various populations globally, local adaptations have resulted in a species with high variability in life history and behavior across different populations. Geographic range The cabbage moth has a wide geographic distribution across parts of Europe and Asia ranging from about 30°N to 70°N in latitude. This geographic range is within the Palearctic region, which includes parts of Europe, Asia north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidoptera
Lepidoptera ( ) is an order (biology), order of insects that includes butterfly, butterflies and moths (both are called lepidopterans). About 180,000 species of the Lepidoptera are described, in 126 Family (biology), families and 46 Taxonomic rank, superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most wikt:speciose, speciose orders, along with the Hymenoptera, fly, Diptera, and beetle, Coleoptera. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, wings, and a proboscis. The scales are modified, flattened "hairs", and give ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caterpillar
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterpi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
