Anthemideae
Anthemideae is a tribe of flowering plants in the family, Asteraceae, and the subfamily Asteroideae. They are distributed worldwide with concentrations in central Asia, the Mediterranean Basin, and southern Africa.Oberprieler, C., et al. (2007) A new subtribal classification of the tribe Anthemideae (Compositae). ''Willdenowia'' 37(1): 89–114. Most species of plant known as chamomile belong to genera of this tribe. As of 2006 there were about 1800 species classified in 111 genera. In 2007 the tribe was divided into 14 subtribes, including Glebionidinae, the source of hybrid garden marguerites. Genera Anthemideae genera recognized by the Global Compositae Database as March 2022: *'' × Anthematricaria'' *'' × Anthemimatricaria'' *'' Aaronsohnia'' *'' Achillea'' *'' Adenanthellum'' *'' Adenoglossa'' *'' Ajania'' *'' Ajaniopsis'' *'' Allardia'' *'' Anacyclus'' *'' Anthemis'' *'' Arctanthemum'' *''Argyranthemum'' *'' Artemisia'' *'' Artemisiella'' *'' Athanas ...

Coss
The kos (Hindi: कोस), also spelled ''coss'', ''koss'', ''kosh'', ''krosh'', and ''krosha'', is a unit of measurement which is derived from a Sanskrit term, क्रोश ''krośa'', which means to "call", as the unit was supposed to represent the distance at which another human could be heard. It is an ancient Indian subcontinental standard unit of distance, in use since at least 4 BC. According to the ''Artha-śāstra'', a ''krośa'' or ''kos'' is about 3000 meters or 1.8 miles. Another conversion is based on the Mughal emperor Akbar, who standardized the unit to 5000 '' guz'' in the Ain-i-Akbari. The British in India standardized Akbar's ''guz'' to 33 inches, making the ''kos'' approximately 4191 meters. Another conversion suggested a ''kos'' to be approximately 2 English miles. Arthashastra Standard units The ''"Arthashastra'': Chapter XX. "Measurement of space and time", authored in 4th century BC by Chanakya (Vishnugupta Kauṭilya), sets this standard breakup of ...

Monotypic Genus
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteraceae
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 t ...
