Rosaceae
Rosaceae (), the rose family, is a family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus '' Rosa''. The family includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and shrubs, such as roses, meadowsweets, rowans, firethorns, and photinias. Among the most species-rich genera in the family are '' Alchemilla'' (270), '' Sorbus'' (260), ''Crataegus'' (260), '' Cotoneaster'' (260), '' Rubus'' (250), and ''Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds.

Exochorda Racemosa
''Exochorda racemosa'', the pearlbush or common pearlbush, is a species of plant in the family Rosaceae. This species is mostly found in China and Japan. Taxonomy and etymology ''Exochorda racemosa'' was first described by John Lindley. It is placed in the genus '' Exochorda'' and family Rosaceae, the rose family. The plant gets its common name, "common pearlbush", from its pearl-looking flowers. Description A loose, irregular or vase-shaped and upright shrub, this species is deciduous. It has oblong leaves, about long and wide, that are rounded and toothed at the margin on the top. The flowers are white, and flower in late April to early May. The flowers have round petals, 12-25 stamen The stamen (: stamina or stamens) is a part consisting of the male reproductive organs of a flower. Collectively, the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament ...s, borne in racemes in groups of about ...

Amygdaloideae
Amygdaloideae is a subfamily within the flowering plant family Rosaceae. It was formerly considered by some authors to be separate from Rosaceae, and the family names Prunaceae and Amygdalaceae have been used. Reanalysis from 2007 has shown that the previous definition of subfamily Spiraeoideae was paraphyletic. To solve this problem, a larger subfamily was defined that includes the former Amygdaloideae, Spiraeoideae, and Maloideae. This subfamily, however, is to be called Amygdaloideae rather than Spiraeoideae under the International Code of Nomenclature for algae, fungi, and plants as updated in 2011. As traditionally defined, the Amygdaloideae includes such commercially important crops as plum, cherry, apricot, peach, and almond. The fruit of these plants are known as stone fruit ( drupes), as each fruit contains a hard shell (the endocarp) called a ''stone'' or ''pit'', which contains the single seed. The expanded definition of the Amygdaloideae adds to these commer ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Exochorda
''Exochorda'' is a small genus of flowering plants in the family Rosaceae, native to China and central Asia (Turkestan). They are used as ornamental plants with the common name pearl bush, or pearlbush. Numerous species have been described on the basis of differing appearance and geographical separation, but a systematic studyGao Fangyou. 1998. Exochorda: ''five species or one?: a biosystematic study of the Rosaceous genus'' Exochorda. Wageningen University Dissertation published as a book. revealed that the different types are closely related and probably all descended from a single species that formerly had a wide distribution that has been fragmented by habitat loss. As a single species the correct name is '' E. racemosa''. Description They are deciduous shrubs growing tall. The leaves are paddle-shaped oval, long, with an entire or bluntly serrated margin. The flowers are white, with five petals, produced in spring on the ends of the branches. The fruit is a dry coccetum ...

Prinsepia
''Prinsepia'' is a genus of trees in the Rosaceae. It bears fruit which looks like a cherry. The various species grow largely in Nepal, India, China, Bangladesh, and Taiwan, though ''P. sinensis'' is hardy in zone 4, to about .

Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." 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 isoto ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxa ranked above species are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lindl
John Lindley FRS (5 February 1799 – 1 November 1865) was an English botanist, gardener and orchidologist. Early years Born in 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 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 Banks who offered him employment as an assistant in his ...

Ludwig Reichenbach
Heinrich Gottlieb Ludwig Reichenbach (8 January 1793 – 17 March 1879) was a German botanist, ornithologist and illustrator. It was he who first requested Leopold and Rudolf Blaschka, Leopold Blaschka to make a set of glass marine invertebrate models for scientific education and museum showcasing, the successful commission giving rise to the creation of the Blaschkas' Glass sea creatures and, subsequently and indirectly, the more famous Glass Flowers. Early life Born in Leipzig and the son of Johann Friedrich Jakob Reichenbach (the author in 1818 of the first Greek-German dictionary) Reichenbach studied medicine and natural science at the University of Leipzig in 1810, becoming a professor and, eight years later in 1818, an instructor. In 1820, he was appointed the director of the Dresden natural history museum and a professor at the Surgical-Medical Academy in Dresden, where he remained for many years.

He was in charge of the botanical garden at Saharanpur and played a role in the development of economic botany in India. Early life John Forbes Royle was the only son of William Henry Royle and Isabella Forbes. While still a child, his father died and Royle studied under Sangster of Haddington before going to study at Edinburgh high school.
