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] |
Parietaria Judaica
''Parietaria judaica'', with common names spreading pellitory or pellitory of the wall, is a species of herbaceous perennial plant in the family Urticaceae. The plant's pollen is highly allergenic. In Australia it is also known as asthma weed, due to the high incidence of allergy. It is unrelated to the herb pellitory (''Anacyclus pyrethrum''). It is easily confused with the very similar species '' Parietaria officinalis''. Etymology ''Parietaria'' (Latin): Wall-dweller (a name used by the Roman naturalist and philosopher Pliny). ''Judaica'' (Latin): Of Judaea, Jewish, from Palestine. Description The biological form of ''Parietaria judaica'' is hemicryptophyte scapose, as its overwintering buds are situated just below the soil surface and the floral axis is more or less erect. This plant has pink or red hairy stems, woody at the base. It reaches on average a height of . The leaves are hairy, alternate, simple, entire and green, with smooth margins.

Naturalisation (biology)
Naturalisation (or naturalization) is the ecological phenomenon through which a species, taxon, or population of exotic (as opposed to native) origin integrates into a given ecosystem, becoming capable of reproducing and growing in it, and proceeds to disseminate spontaneously. In some instances, the presence of a species in a given ecosystem is so ancient that it cannot be presupposed whether it is native or introduced. Generally, any introduced species may (in the wild) either go extinct or naturalise in its new environment. Some populations do not sustain themselves reproductively, but exist because of continued influx from elsewhere. Such a non-sustaining population, or the individuals within it, are said to be adventive. Cultivated plants are a major source of adventive populations. The above refers to ''naturalize'' as an intransitive verb, as in, "The species naturalized". In North America it is common to use ''naturalize'' as a transitive verb, as in, "City staff nat ...

Weed
A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place", or a plant growing where it is not wanted.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24. This introduces the concept of humans and their goals in a particular setting.Holzner, W., & Numata, M. (Eds.). (2013). ''Biology and ecology of weeds'' (Vol. 2). Springer Science & Business Media. The concept of weeds is particularly significant in agriculture, where the aim is growing crops or pastures of a single species, or a mixture of a few desired species. In such environments, other plant species are considered undesirable and therefore a weed. Besides, some weeds have undesirable characteristics making them a plant pest in most human settings.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds.

Parietaria Officinalis
''Parietaria officinalis'', the eastern pellitory-of-the-wall, also known as upright pellitory and lichwort, is a plant of the nettle family. Its leaves, however, are non-stinging. The plant grows on rubbish and on walls, hence the name. The pollen is a cause of allergy. Uses It was once used in the making of certain metheglins. Chemistry The leaves and flowers of ''P. officinalis'' contains the flavonoids kaempferol-3- bioside, the 3-glucosides and 3-rutinosides of quercetin, kaempferol and isorhamnetin, 3-sophorosides of quercetin and kaempferol and 3-neohesperosides of kaempferol and isorhamnetin. They also contain caffeoylmalic and two pyrrole acids. See also It is in a different family from ''Anacyclus pyrethrum'', also called pellitory.
