Rosularia Globulariifolia
''Rosularia'' is a small genus of the family Crassulaceae. It includes about 28-35 species from Europe, the Himalayas, and northern Africa. Taxonomy ''Rosularia'' was originally described by De Candolle (1828) as a section of the genus ''Umbilicus'', and raised to the level of genus by Stapf (1923) Thus the genus bears the botanical authority ( DC) Stapf of both authors. In 1930, Berger included it in family Crassulaceae subfamily Sedoideae, as one of 9 genera. He further divided it into two sections (Eu-Rosularia and Ornithogalopsis) and further series, transferring some species of ''Sedum'' to it. Since then, a number of species have been transferred in and out of the genus, including '' S. sempervivoides'', which at one stage was placed in '' Prometheum''. The genus ''Sempervivella'' was submerged in ''Rosularia''. The genus is now placed within the Leucosedum clade, tribe Sedeae, subfamily Sempervivoideae of the Crassulaceae, but is embedded within ''Sedum'' paraphyleti ...

De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss people, Swiss botany, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paraphyletically
Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term received currency during the debates of the 1960s and 1970s accompanying the rise of cladistics, having been coined by zoologist Willi Hennig to apply to well-known taxa like Reptilia (reptiles), which is paraphyletic with respect to birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancestor except f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rosularia Aizoon
''Rosularia aizoon'' is a succulent that forms rosettes of hairy, pale green to blue-green leaves. It is hardy down to zone 7a (-17 °C, 0 °F) and blooms in summer. The plant was first described as ''Prometheun aizoon'' by Eduard Fenzl then transferred to genus ''Rosularia'' by Alwin Berger Alwin Berger (28 August 1871 – 20 April 1931) was a German botanist best known for his contribution to the nomenclature of succulent plants, particularly agaves and cacti.
