Sigesbeckia Glabrescens
''Sigesbeckia'' is a genus of annual plants in the family Asteraceae. St. Paul's wort is a common name for some of the species. ''Sigesbeckia'' is widely distributed and has been traditionally used for the management of chronic diseases, including arthritis. Origin ''Sigesbeckia'' is named for a botanist Johann Georg Siegesbeck, who was a strong critic of Carl Linnaeus's botanic classification system. He was known to refer to it as "loathsome harlotry" because of the focus of the system upon the presence of (or lack of) sex organs in plants and their locations and groupings. Siegesbeck tried to refute Linnaeus' sexual classification system, but was unable to provide sound scholastic arguments to support his arguments. Linnaeus proposed in ''Critica Botanica'' that there should be a link between the plant and the botanist after whom it was named. Considering the feud between Siegesbeck and Linnaeus, it is not unsurprising that in the classification book ''Hortus Cliffortianus'', ...

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] |
