Abutilon Guineense
''Abutilon guineense'' is a species of flowering plant in the mallow family, Malvaceae. It has a broad distribution in Africa and has been introduced elsewhere. It may comprise more than one species, with others yet undescribed. In China it occurs in Hainan, Sichuan, and Yunnan. ''Abutilon guineense'' was originally described by Heinrich Christian Friedrich Schumacher in 1829 as ''Sida guineensis''. Two varieties are accepted: *''Abutilon guineense''. var.

Heinrich Christian Friedrich Schumacher
Heinrich Christian Friedrich Schumacher (15 November 1757 in Glückstadt, Holstein – 9 December 1830) was a Danish surgeon, botanist and professor of anatomy at the University of Copenhagen. Schumacher carried out significant research work in malacology, in other words on molluscs, and described several taxa. Life Early years (1757-1778) He was born to Joachim Christian Schumacher, a sergeant in the infantry of the Duchy of Schleswig, and his wife, Caroline Magdalene in Glückstadt in present-day Germany. In spite of his family's limited means, he received a good upbringing, and was sent to grammar school in Rendsburg. After confirmation became the apprentice of the regiment surgeon, Mehl, a learned and skilled man, who gave his eager student a thorough introduction to both medicine and botany, thereby waking Schumacher's natural gift for science. By 1773, at the age of 16, his keen efforts got him appointed as a military surgeon with his father's battalion in the army sta ...

Arthur Wallis Exell
Arthur Wallis Exell OBE (21 May 1901, in Birmingham – 15 January 1993, in Cheltenham) was initially an assistant and later Deputy Keeper of Botany at the British Museum during the years 1924–1939 and 1950–1962. A noted cryptographer, taxonomist and phytogeographer, he was notable for his furthering of botanical exploration in tropical and sub-tropical Africa, and was an authority on the family Combretaceae. Exell's formal education started at Queen Elizabeth Grammar School in Warwickshire, and then King Edmund's School in Birmingham. From there he went on to Emmanuel College, Cambridge and was awarded an M.A. in 1926, having joined the British Museum as a second-class assistant on 11 August 1924, eventually becoming Deputy Keeper of Botany in 1950. He was entrusted with the Polypetalae, although his first paper was a morphological study of the hymenium in three species of fungus. Exell's first contact with Africa was in 1932/3 when he travelled to the islands in the Gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 a ...

Hainan
Hainan (, ; ) is the smallest and southernmost province of the People's Republic of China (PRC), consisting of various islands in the South China Sea. , the largest and most populous island in China,The island of Taiwan, which is slightly larger, is claimed but not controlled by the PRC. It is instead controlled by the Republic of China, a '' de facto'' separate country. makes up the vast majority (97%) of the province. The name means "south of the sea", reflecting the island's position south of the Qiongzhou Strait, which separates it from Leizhou Peninsula.

Calyx (botany)
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, a ...

Plants Described In 1829
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the abil ...
