Pulicaria Dysenterica
''Pulicaria dysenterica'', the common fleabane, or, in North America, meadow false fleabane, is a species of fleabane in the family Asteraceae. It is native to Europe and western Asia where it grows in a variety of habitats ranging from semi-arid Mediterranean woodlands to wetter situations. ''Pulicaria dysenterica'' is perennial and can form dense clusters of plants, spreading by its roots. It flowers at its maximum height of about . Leaves are alternately arranged and clasp the stem, which itself contains a salty-astringent liquid. The yellow inflorescences are typically composed of a prominent centre of 40–100 disc florets surrounded by 20–30 narrow, pistillate ray florets. When setting seed the flower heads reflex. Common fleabane is the main food plant for the Fleabane Tortoise Beetle ( Cassida murraea), and for four micromoths, Apodia bifractella, Ptocheuusa paupella, Dusky Plume ( Oidaematophorus lithodactyla) and Digitivalva pulicariae.

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné 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". 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 the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dysentery
Dysentery (UK pronunciation: , US: ), historically known as the bloody flux, is a type of gastroenteritis that results in bloody diarrhea. Other symptoms may include fever, abdominal pain, and a feeling of incomplete defecation. Complications may include dehydration. The cause of dysentery is usually the bacteria from genus ''Shigella'', in which case it is known as shigellosis, or the amoeba ''Entamoeba histolytica''; then it is called amoebiasis. Other causes may include certain chemicals, other bacteria, other protozoa, or parasitic worms. It may spread between people. Risk factors include contamination of food and water with feces due to poor sanitation. The underlying mechanism involves inflammation of the intestine, especially of the colon. Efforts to prevent dysentery include hand washing and food safety measures while traveling in areas of high risk. While the condition generally resolves on its own within a week, drinking sufficient fluids such as oral rehydration s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The frass Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the ... is deposited in irregularly dispersed grains.

Ray Flower
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Johann Jakob Bernhardi
Johann Jakob Bernhardi (1 September 1774, in Erfurt – 13 May 1850, in Erfurt) was a German doctor and botanist. Biography Johann J. Bernhardi studied Medicine and Botany at the University of Erfurt, and after graduation practiced medicine for a time in his native city. In 1799 he was named director of the botanical garden at ''Gartenstraße'', and in 1809 was appointed professor of botany, zoology, mineralogy and materia medica at the university. He served as director of the botanical garden until his death in 1850, being buried in the central avenue of this botanical garden. Throughout his life thanks to acquisitions and interchanges with other botanists, he assembled a considerable herbarium of 60,000 plants with specimens from North America, South America, Asia, and Africa. After his death this herbarium did not remain in Germany but due to the efforts of George Engelmann, who, in 1857, shortly after the death of Bernhardi bought the complete herbarium for the amount of 600 do ...

Head (botany)
A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomorp ...
