Irano-Turanian Region
The Irano-Turanian Region is a floristic region located within the Tethyan Subkingdom of the Holarctic Kingdom. It is divided into 12 floristic provinces according to the work of Armen Takhtajan, a Soviet-Armenian botanist who created a classification system for flowering plants. One of the main characteristics of the region is a great diversity and abundance of species, especially in the Iranian Plateau. The region's climate is predominantly continental Continental may refer to: Places * Continent, the major landmasses of Earth * Continental, Arizona, a small community in Pima County, Arizona, US * Continental, Ohio, a small town in Putnam County, US Arts and entertainment * ''Continental'' ( ..., with most of the precipitation occurring in the winter and spring.

Archaeophyte
An archaeophyte is a plant species which is non-native to a geographical region, but which was an introduced species in "ancient" times, rather than being a modern introduction. Those arriving after are called neophytes. The cut-off date is usually the beginning of the early modern period (turn of the 15th or 16th century). In Britain, archaeophytes are considered to be those species first introduced prior to the year 1492, when Christopher Columbus arrived in the New World and the Columbian Exchange began. Background Archaeophytes include numerous weed species the seeds of which have been found in archaeological excavations - to which they had been brought by people ( anthropochory), animals (zoochory) or the wind (anemochory). In some cases, introduced species, whether archaeophytes or neophytes, may have been native species before the ice ages, which extirpated vast numbers of plant species. Central European archaeophytes almost all come from the Mediterranean region and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chenopodium
''Chenopodium'' is a genus of numerous species of perennial or annual herbaceous flowering plants known as the goosefoots, which occur almost anywhere in the world. It is placed in the family Amaranthaceae in the APG II system; older classification systems, notably the widely used Cronquist system, separate it and its relatives as Chenopodiaceae, but this leaves the rest of the Amaranthaceae polyphyletic. However, among the Amaranthaceae, the genus ''Chenopodium'' is the namesake member of the subfamily Chenopodioideae. Description The species of ''Chenopodium'' (s.str., description according to Fuentes et al. 2012) are annual or perennial herbs, shrubs or small trees. They generally rely on alkaline soil. They are nonaromatic, but sometimes fetid. The young stems and leaves are often densely covered by vesicular globose hairs, thus looking farinose. Characteristically, these trichomes persist, collapsing later and becoming cup-shaped. The branched stems grow erect, ascen ...
