Gnaphalieae
The Gnaphalieae are a tribe of flowering plants in the family Asteraceae. It is most closely related to the tribes Anthemideae, Astereae, and Calenduleae. Characteristics This group is most diverse in South America, Southern Africa and Australia. There are only a few genera with species native to temperate regions: ''Anaphalis'', ''Antennaria'', ''Gamochaeta'', ''Helichrysum'', ''Leontopodium'' (Edelweiss), '' Phagnalon'', ''Diaperia'', and ''Pseudognaphalium''. The classification of the tribe into subtribes is unclear, with a number of past classifications not being supported by late 20th-century evidence. Genera Gnaphalieae genera recognized by the Global Compositae Database as April 2022: *'' × Filfia'' *'' Acanthocladium'' *''Achyrocline'' *''Acomis'' *'' Actinobole'' *'' Alatoseta'' *''Ammobium'' *'' Amphiglossa'' *'' Anaphalioides'' *''Anaphalis'' *'' Anaxeton'' *'' Ancistrocarphus'' *'' Anderbergia'' *'' Anemocarpa'' *'' Angianthus'' *''Antennaria'' *' ...

Australian Plant Name Index
The Australian Plant Name Index (APNI) is an online database of all published names of Australian vascular plants. It covers all names, whether current names, synonyms or invalid names. It includes bibliographic and typification details, information from the Australian Plant Census including distribution by state, links to other resources such as specimen collection maps and plant photographs, and the facility for notes and comments on other aspects. History Originally the brainchild of Nancy Tyson Burbidge, it began as a four-volume printed work consisting of 3,055 pages, and containing over 60,000 plant names. Compiled by Arthur Chapman, it was part of the Australian Biological Resources Study (ABRS). In 1991 it was made available as an online database, and handed over to the Australian National Botanic Gardens. Two years later, responsibility for its maintenance was given to the newly formed Centre for Plant Biodiversity Research. Scope Recognised by Australian herbaria as the ...

Asteraceae Genera
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 technically ...

Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...

Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
