Malvaceae
Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao and durian. There are also some genera containing familiar ornamentals, such as ''Alcea'' (hollyhock), ''Malva'' (mallow), and ''Tilia'' (lime or linden tree). The largest genera in terms of number of species include ''Hibiscus'' (300 species), ''Sterculia'' (250 species), ''Dombeya'' (250 species), '' Pavonia'' (200 species) and '' Sida'' (200 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae '' sensu stricto'' comprise a very homogeneous and cladistically monophyletic group. Another major circumscription, Malvaceae ''sensu lato'', has been more recently defined on the basis that genetics studies have shown the commonly recognised families Bombacaceae, Tiliaceae, and Sterculiaceae, which have always been considered closely allie ...

Zacryptocerus Alveolatus
''Cephalotes alveolatus'' is an extinct species of ant in the subfamily Myrmicinae known from a single Middle Miocene fossil found in amber on Hispaniola. At the time of description ''C. alveolatus'' was one of seven fossil ant species placed in the ''Cephalotes'' ''coffeae'' clade. History and classification ''Cephalotes alveolatus'' was described from a single fossil ant preserved as an inclusion in a transparent chunk of Dominican amber. The amber was produced by the extinct ''Hymenaea protera'', which formerly grew on Hispaniola, across northern South America and up to southern Mexico. The specimen was collected from an unidentified amber mine in the Dominican Republic. The amber dates from the Burdigalian stage of the Miocene being recovered from sections of the La Toca Formation in the Cordillera Septentrional and the Yanigua Formation in the Cordillera Oriental. At the time of description, the holotype specimen was preserved in the private collection of Joachim Scheven i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myrmicinae
Myrmicinae is a subfamily of ants, with about 140 extant genera; their distribution is cosmopolitan. The pupae lack cocoons. Some species retain a functional sting. The petioles of Myrmicinae consist of two nodes. The nests are permanent and in soil, rotting wood, under stones, or in trees.Goulet, H & Huber, JT (eds.) (1993) Hymenoptera of the world: an identification guide to families. Agriculture Canada. p. 224 Identification Myrmicine worker ants have a distinct postpetiole, i.e., abdominal segment III is notably smaller than segment IV and set off from it by a well-developed constriction; the pronotum is inflexibly fused to the rest of the mesosoma, such that the promesonotal suture is weakly impressed or absent, and a functional sting is usually present. The clypeus is well-developed; as a result, the antennal sockets are well separated from the anterior margin of the head. Most myrmicine genera possess well-developed eyes and frontal lobes that partly conceal the an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lardizabalaceae
Lardizabalaceae is a family of flowering plants. The family has been universally recognized by taxonomists, including the APG II system (2003; unchanged from the APG system of 1998), which places it in the order Ranunculales, in the clade eudicots. The family consist of 7 genera with about 40 known species of woody plants. All are lianas, save ''Decaisnea'', which are pachycaul shrubs. The leaves are alternate, and compound (usually palmate), with pulvinate leaflets. The flowers are often in drooping racemes. They are found in eastern Asia, from the Himalayas to Japan, with the exception of the genera ''Lardizabala'' and ''Boquila'', both native to southern South America (Chile, and ''Boquila'' also in adjacent western Argentina Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America.

Middle Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sargentodoxa Globosa
''Sargentodoxa'' is a monotypic genus of flowering plants belonging to the family Lardizabalaceae. It only contains one known species, Sargentodoxa cuneata (Oliv.) Rehder & E.H.Wilson Its native range is China (north-Central, south-Central and southeast) to Indo-China. It is also found in Hainan, Laos and Vietnam.

He was appointed in 1872 as the first director of Harvard University's Arnold Arboretum in Boston, Massachusetts Massachusetts (Massachusett: ''Muhsachuweesut Massachusett_writing_systems.html" ;"title="nowiki/> məhswatʃəwiːsət.html" ;"title="Massachusett writing systems">məhswatʃəwiːsət">Massachusett writing systems">məhswatʃəwiːsət'' En ....

Quercus Hiholensis Acorn UWBM 56470-3 Pigg & Wehr 2002 Plt2 Fig16
An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably ''Lithocarpus'' (stone oaks), as well as in those of unrelated species such as ''Grevillea robusta'' (silky oaks) and the Casuarinaceae (she-oaks). The genus ''Quercus'' is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 90 in the United States. The second greatest area of oak diversity is China, with approximately 100 species. Description Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. Man ...
