Salicaceae Genera
The Salicaceae are the willow family of flowering plants. The traditional family (Salicaceae ''sensu stricto'') includes the willows, poplars. Genetic studies summarized by the Angiosperm Phylogeny Group (APG) have greatly expanded the circumscription of the family to contain 56 genera and about 1220 species, including the tropical Scyphostegiaceae and many of the former Flacourtiaceae. In the Cronquist system, the Salicaceae were assigned to their own order, Salicales, and contained three genera, ''Salix'', ''Populus'', and ''Chosenia'' (now a synonym of ''Salix''). Recognized to be closely related to the Violaceae and Passifloraceae, the family is placed by the APG in the order Malpighiales. Under the new circumscription, most members of the family are trees or shrubs that have simple leaves with alternate arrangement, and temperate members are usually deciduous. Most members have serrate or dentate leaf margins, and many of those that have such toothed margins exhibit sal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 mya (unit), million years ago (Mya). It is the third and final period of the Mesozoic Era (geology), Era, as well as the longest. At around 77.1 million years, it is the ninth and longest geological period of the entire Phanerozoic. The name is derived from the Latin , 'chalk', which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation . The Cretaceous was a period with a relatively warm climate, resulting in high Sea level#Local and eustatic, eustatic sea levels that created numerous shallow Inland sea (geology), inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic gr ...

Violaceae
Violaceae is a family of flowering plants established in 1802, consisting of about 1000 species in about 25 genera. It takes its name from the genus '' Viola'', the violets and pansies. Older classifications such as the Cronquist system placed the Violaceae in an order named after it, the Violales or the Parietales. However, molecular phylogeny studies place the family in the Malpighiales as reflected in the Angiosperm Phylogeny Group (APG) classification, with 41 other families, where it is situated in the parietal clade of 11 families. Most of the species are found in three large genera, '' Viola'', '' Rinorea'' and '' Hybanthus''. The other genera are largely monotypic or oligotypic. The genera are grouped into four clades within the family. The species are largely tropical or subtropical but ''Viola'' has a number of species in temperate regions. Many genera have a very restricted distribution. Description Though the best-known genus, ''Viola'', is herbaceous, mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bembicia
''Bembicia'' is a genus of flowering plants belonging to the family Salicaceae The Salicaceae are the willow family of flowering plants. The traditional family (Salicaceae ''sensu stricto'') includes the willows, poplars. Genetic studies summarized by the Angiosperm Phylogeny Group (APG) have greatly expanded the circumsc .... It contains a single species, ''Bembicia axillaris''. Its native range is Madagascar.
