Christiaan Hendrik Persoon
Christiaan Hendrik Persoon (1 February 1761 – 16 November 1836) was a German mycologist who made additions to Linnaeus' mushroom taxonomy. Early life Persoon was born in South Africa at the Cape of Good Hope, the third child of an immigrant Pomeranian father and Dutch mother. His mother died soon after he was born; at the age of thirteen his father (who died a year later) sent him to Europe for his education. Education Initially studying theology at Halle, at age 22 (in 1784) Persoon switched to medicine at Leiden and Göttingen. He received a doctorate from the "Kaiserlich-Leopoldinisch-Carolinische Deutsche Akademie der Naturforscher" in 1799. Later years He moved to Paris in 1802, where he spent the rest of his life, renting an upper floor of a house in a poor part of town. He was apparently unemployed, unmarried, poverty-stricken and a recluse, although he corresponded with botanists throughout Europe. Because of his financial difficulties, Persoon agreed to dona ...

Annual Plant
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. The length of growing seasons and period in which they take place vary according to geographical location, and may not correspond to the four traditional seasonal divisions of the year. With respect to the traditional seasons, annual plants are generally categorized into summer annuals and winter annuals. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. One seed-to-seed life cycle for an annual plant can occur in as little as a month in some species, though most last several months. Oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is often used in classrooms for education. Many desert annuals are therophytes, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of North America
The ''Flora of North America North of Mexico'' (usually referred to as ''FNA'') is a multivolume work describing the native plants and naturalized plants of North America, including the United States, Canada, St. Pierre and Miquelon, and Greenland. It includes bryophytes and vascular plants. All taxa are described and included in dichotomous keys, distributions of all species and infraspecific taxa are mapped, and about 20% of species are illustrated with line drawings prepared specifically for FNA. It is expected to fill 30 volumes when completed and will be the first work to treat all of the known flora north of Mexico; in 2015 it was expected tha the series would conclude in 2017. Twenty-nine of the volumes have been published as of 2022. Soon after publication, the contents are made available online. FNA is a collaboration of about 1,000 authors, artists, reviewers, and editors from throughout the world. Reception The series has been praised for "the comprehensive treatme ...

Plantlife is the international conservation membership charity working to secure a world rich in wild plants and fungi. It is the only UK membership charity dedicated to conserving wild plants and fungi in their natural habitats and helping people to enjoy and learn about them. HM King Charles III is patron of the charity. Plantlife works across all key plant ecosystems and habitats focussing on specific habitats and species depending on need. They promote the importance of all plants and fungi for a sustainable and healthy planet and at present have a particular focus in the UK on grasslands temperate forests due to their acute vulnerability and on at-risk species recovery. Founded in 1989, Plantlife now has 15,000 members and many more supporters. Plantlife enhances, restores, protects and celebrates natural heritage through working with landowners, other conservation organisations, public sector bodies, the private sector and the wider public.

Cerastium
''Cerastium'' is a genus of annual, winter annual, or perennial plants belonging to the family Caryophyllaceae. They are commonly called mouse-ear chickweed. Species are found nearly worldwide but the greatest concentration is in the northern temperate regions. There are about 200 species. A number are common weeds in fields and on disturbed ground. ''Cerastium'' species are used as food plants by the larvae of some Lepidoptera species including ''Coleophora chalcogrammella'' (which feeds exclusively on ''Cerastium arvense'') and ''Coleophora striatipennella'' (which has been recorded on ''Cerastium fontanum''). Selected species *'' Cerastium aleuticum'' – Aleutian chickweed *'' Cerastium alpinum'' – alpine chickweed *''Cerastium arcticum'' – arctic mouse-ear chickweed *''Cerastium arvense'' – field chickweed *'' Cerastium axillare'' – Trans-Pecos chickweed *''Cerastium beeringinanum'' – Bering chickweed *'' Cerastium bialynickii'' *'' Cerastium biebersteinii'' – ...
