Daniel Solander
Daniel Carlsson Solander or Daniel Charles Solander (19 February 1733 – 13 May 1782) was a Sweden, Swedish naturalist and an Apostles of Linnaeus, apostle of Carl Linnaeus. Solander was the first university-educated scientist to set foot on Australian soil. Biography Solander was born in Piteå, Norrbotten, Sweden, to Rev. Carl Solander a Lutheran principal, and Magdalena (née Bostadia). Solander enrolled at Uppsala University in July 1750 and initially studied languages, the humanities and law. The professor of botany was the celebrated Carl Linnaeus, who was soon impressed by young Solander's ability and accordingly persuaded his father to let him study natural history. Solander travelled to England in June 1760 to promote the new Linnean system of classification. In February 1763, he began librarian, cataloguing the natural history collections of the British Museum, and was elected a Fellow of the Royal Society in June the following year.

Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss 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 light, suggestin ...

Joseph Gaertner
Joseph Gaertner (12 March 1732 – 14 July 1791) was a German botanist, best known for his work on seeds, '' De Fructibus et Seminibus Plantarum'' (1788-1792). Biography He was born in Calw, and studied in Göttingen under Albrecht von Haller. He was primarily a naturalist, but also worked at physics and zoology. He travelled extensively to visit other naturalists. He was professor of anatomy in Tübingen in 1760, and was appointed professor of botany at St Petersburg in 1768, but returned to Calw in 1770. Gaertner made back cross to convert one species into another. Back cross increases nuclear gene frequency His observations were: 1. Dominance of traits 2. Equal contribution of male and female to the progeny 3. No variation in F1 (first generation of descendants) 4. Large variation in F2 (second generation of descendants) including parental and intermediate types 5. Some of F2 plants had entirely new traits but he was unable to give possible explanation for ...

Achille Richard
Achille Richard was a French botanist, botanical illustrator and physician (27 April 1794 in Paris – 5 October 1852). Biography Achille was the son of the botanist Louis-Claude Marie Richard (1754–1821). He was a pharmacist in the French navy, and a member of several well-known societies of that time. He became a botanical leader, and his books remain valued for their clarity and precision. On 24 February 1834 he was made a member of the French Academy of Sciences (Botanical Section). He was also a member of the French National Academy of Medicine. He studied and described several genera of orchids that take his abbreviation in the generic name, among them ''Ludisia''.

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] |
Coffea
''Coffea'' is a genus of flowering plants in the family Rubiaceae. ''Coffea'' species are shrubs or small trees native to tropical and southern Africa and tropical Asia. The seeds of some species, called coffee beans, are used to flavor various beverages and products. The fruits, like the seeds, contain a large amount of caffeine, and have a distinct sweet taste and are often juiced. The plant ranks as one of the world's most valuable and widely traded commodity crops and is an important export product of several countries, including those in Central and South America, the Caribbean and Africa. Cultivation and use There are over 120 species of ''Coffea'', which is grown from seed. The two most popular are ''Coffea arabica'' (commonly known simply as "Arabica"), which accounts for 60–80% of the world's coffee production, and ''Coffea canephora'' (known as "Robusta"), which accounts for about 20–40%. '' C. arabica'' is preferred for its sweeter taste, while ''C. canephora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubiaceae
The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include '' Coffea'', the source of coffee, '' Cinchona'', the source of the antimalarial alkaloid quinine, ornamental cultivars (''e.g.'', '' Gardenia'', '' Ixora'', '' Pentas''), and historically some dye plants (''e.g.'', '' Rubia''). Description The Rubiaceae are morphologically easily recognizable as a coherent group by a combination of characters: opposite or whorled leaves that are simple and entire, interpetiolar sti ...

Prodromus Systematis Naturalis Regni Vegetabilis
''Prodromus Systematis Naturalis Regni Vegetabilis'' (1824–1873), also known by its standard botanical abbreviation ''Prodr. (DC.)'', is a 17-volume treatise on botany initiated by Augustin Pyramus de Candolle. De Candolle intended it as a summary of all known seed plants, encompassing taxonomy, ecology, evolution and biogeography. He authored seven volumes between 1824 and 1839, but died in 1841. His son, Alphonse de Candolle, then took up the work, editing a further ten volumes, with contributions from a range of authors. Volume 17 was published in October 1873. The fourth and final part of the index came out in 1874. The ''Prodromus'' remained incomplete, dealing only with dicotyledons. In the ''Prodromus'', De Candolle further developed his concept of families. Note that this system was published well before there were internationally accepted rules for botanical nomenclature. Here, a family is indicated as "ordo". Terminations for families were not what they are now. Neit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen reco ...

Monotypic Rubiaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...
