Daubenya Capensis
''Daubenya'' is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae (also treated as the family Hyacinthaceae).Stevens, P.F. (2001 onwards),Asparagales: Scilloideae, ''Angiosperm Phylogeny Website'', retrieved 2013-03-28 It is native to the Cape Province of South Africa. At first believed to consist of a single species, ''Daubenya aurea'', the genus was expanded in 2000 to include the genera ''Androsiphon'' and '' Amphisiphon'' and various species that had previously been classified as ''Polyxena'', ''Massonia'', or '' Neobakeria''. ''"The poor congruence between morphological and other characters within Hyacinthaceae has also made generic circumscriptions very difficult. One of the consequences of this has been the recognition of a large number of genera that are poorly defined morphologically."''- (Speta 1998) Description Species of ''Daubenya'' grow from bulbs covered with a brownish tunic. Each bulb produces only two leaves, which appear wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Lindley
John Lindley Fellow of the Royal Society, FRS (5 February 1799 – 1 November 1865) was an English botanist, gardener and orchidology, orchidologist. Early years Born in Old Catton, Catton, near Norwich, England, John Lindley was one of four children of George and Mary Lindley. George Lindley was a nurseryman and pomologist and ran a commercial nursery garden. Although he had great horticultural knowledge, the undertaking was not profitable and George lived in a state of indebtedness. As a boy he would assist in the garden and also collected wild flowers he found growing in the Norfolk countryside. Lindley was educated at Norwich School. He would have liked to go to university or to buy a commission in the army but the family could not afford either. He became Belgium, Belgian agent for a London seed merchant in 1815. At this time Lindley became acquainted with the botanist William Jackson Hooker who allowed him to use his botanical library and who introduced him to Sir Joseph ...

Monkey Beetle
Monkey beetles are scarab beetles, a group of around 70 genera and 850 described species within the tribe Hopliini. The placement of this tribe within the family Scarabaeidae is uncertain between Melolonthinae and Rutelinae. Many species visit flowers for pollen and nectar, or to browse on the petals. The beetles are important pollinators of Aizoaceae and Asteraceae in grazed and ungrazed areas, as well as many others. They tend to favor flowers of white, yellow, pink, orange, and blue pigments. They also tend to favor flowers of symmetrical, abstract patterns.Shelley A Johnson, Susan W Nicolson, Pollen digestion by flower-feeding Scarabaeidae: protea beetles (Cetoniini) and monkey beetles (Hopliini), Journal of Insect Physiology, Volume 47, Issue 7, 2001, Pages 725-733, ISSN 0022-1910, https://doi.org/10.1016/S0022 1910(00)00166-9. Due to their pollination patterns, many plants evolved special features in order to attract monkey beetles, such as the Iridaceae which now have bri ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
