Carl Linnaeus, also known after his ennoblement as Carl von Linné, was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin, and his name is rendered in Latin as Carolus Linnæus.
A cotyledon is a significant part of the embryo within the seed of a plant, and is defined as "the embryonic leaf in seed-bearing plants, one or more of which are the first to appear from a germinating seed." The number of cotyledons present is one characteristic used by botanists to classify the flowering plants (angiosperms). Species with one cotyledon are called monocotyledonous ("monocots"). Plants with two embryonic leaves are termed dicotyledonous ("dicots").
Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".
Nymphaeaceae is a family of flowering plants, commonly called water lilies. They live as rhizomatous aquatic herbs in temperate and tropical climates around the world. The family contains five genera with about 70 known species. Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on or emergent from the surface. Leaves are round, with a radial notch in Nymphaea and Nuphar, but fully circular in Victoria and Euryale.
Anders (Andreas) Dahl was a Swedish botanist and student of Carl Linnaeus. The dahlia flower is named after him.
The Caprifoliaceae or honeysuckle family is a clade of dicotyledonous flowering plants consisting of about 860 species in 42 genera, with a nearly cosmopolitan distribution. Centres of diversity are found in eastern North America and eastern Asia, while they are absent in tropical and southern Africa.
In botany, a berry is a fleshy fruit without a stone (pit) produced from a single flower containing one ovary. Berries so defined include grapes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines) and bananas, but exclude certain fruits that meet the culinary definition of berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible "pericarp". Berries may be formed from one or more carpels from the same flower. The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as peppers, with air rather than pulp around their seeds.
William Thomas Stearn was a British botanist. Born in Cambridge in 1911, he was largely self-educated, and developed an early interest in books and natural history. His initial work experience was at a Cambridge bookshop, but he also had a position as an assistant in the university botany department. At the age of 29 he married Eldwyth Ruth Alford, who later became his collaborator. He died in London in 2001.
Doryanthes is the sole genus in the flowering plant family Doryanthaceae. The genus consists of two species, D. excelsa and D. palmeri, both endemic natives of the coast of Eastern Australia. Doryanthaceae is part of the order Asparagales.
Ornithogalum umbellatum, the garden star-of-Bethlehem, grass lily, nap-at-noon, or eleven-o'clock lady, a species of the genus Ornithogalum, is a perennial bulbous flowering plant in the asparagus family (Asparagaceae). O. umbellatum is a relatively short plant, occurring in tufts of basal linear leaves, producing conspicuous white flowers, in a stellate pattern, in mid to late spring. The flowers open late in the day, but when closed have a green stripe on the outside. It is native throughout most of southern and central Europe, and north-western Africa. O. umbellatum is often grown as a garden ornamental, but in North America and other areas it has escaped cultivation and can be found in many areas, where it may become an invasive noxious weed. Parts of the plant are considered poisonous, but are used in some regional cuisines. Essences are also sold as patent remedies. O. umbellatum has been depicted in art by artists such as Leonardo da Vinci, and folklore has suggested it originally grew from fragments of the star of Bethlehem, hence its horticultural name.
Philosophia Botanica was published by the Swedish naturalist and physician Carl Linnaeus (1707–1778) who greatly influenced the development of botanical taxonomy and systematics in the 18th and 19th centuries. It is "the first textbook of descriptive systematic botany and botanical Latin". It also contains Linnaeus's first published description of his binomial nomenclature.
Cultivated plant taxonomy is the study of the theory and practice of the science that identifies, describes, classifies, and names cultigens—those plants whose origin or selection is primarily due to intentional human activity. Cultivated plant taxonomists do, however, work with all kinds of plants in cultivation.
Genera Plantarum is a publication of Swedish naturalist Carl Linnaeus (1707–1778). The first edition was issued in Leiden, 1737. The fifth edition served as a complementary volume to Species Plantarum (1753). Article 13 of the International Code of Nomenclature for algae, fungi, and plants states that "Generic names that appear in Linnaeus' Species Plantarum ed. 1 (1753) and ed. 2 (1762–63) are associated with the first subsequent description given under those names in Linnaeus' Genera Plantarum ed. 5 (1754) and ed. 6 (1764)." This defines the starting point for nomenclature of most groups of plants.
Critica Botanica was written by Swedish botanist, physician, zoologist and naturalist Carl Linnaeus (1707–1778). The book was published in Germany when Linnaeus was twenty-nine with a discursus by the botanist Johannes Browallius (1707–1755), bishop of Åbo. The first edition was published in July 1737 under the full title Critica botanica in qua nomina plantarum generica, specifica & variantia examini subjiciuntur, selectoria confirmantur, indigna rejiciuntur; simulque doctrina circa denominationem plantarum traditur. Seu Fundamentorum botanicorum pars IV Accedit Johannis Browallii De necessitate historiae naturalis discursus.
Fundamenta Botanica was one of the major works of the Swedish botanist, zoologist and physician Carl Linnaeus (1707–1778) and issued both as a separate work and part of the Bibliotheca Botanica.
Bibliotheca Botanica is a botany book by Swedish naturalist Carl Linnaeus (1707–1778). The book was written and published in Amsterdam when Linnaeus was twenty-eight and dedicated to the botanist Johannes Burman (1707–1779). The first edition appeared in 1735 with the full title Bibliotheca Botanica recensens libros plus mille de plantis huc usque editos secundum systema auctorum naturale in classes, ordines, genera et species; it was an elaborate classification system for his catalogue of books.
Cryptostylis erecta, commonly known as the bonnet orchid or tartan tongue orchid , is an orchid endemic to south eastern Australia. A small and common plant, it has dark green lance-shaped to egg-shaped leaves and up to twelve greenish flowers with a large, bonnet-like or hood-like, lilac-coloured labellum with a network of purple veins.
Commemoration of Carl Linnaeus has been ongoing for over two centuries. Celebrated for his scientific work, Linnaeus was knighted and granted nobility in life. After his death, he has been featured in sculpture, on postage stamps and banknotes, as well as by a medal from the eponymous Linnean Society of London. Several notable people have the given names Linnaeus/Linné or Linnea/Linnéa. Among other things named in his honor are plants, astronomical features, towns, an arboretum, a mineral and a university.
Pelorism is the term, said to be first used by Charles Darwin, for the formation of 'peloric flowers' which botanically is the abnormal production of actinomorphic flowers in a species that usually produces zygomorphic flowers. These flowers are spontaneous floral symmetry mutants. The term epanody is also applied to this phenomenon. Bilaterally symmetrical (zygomorphic) flowers are known to have evolved several times from radially symmetrical (actinomorphic) flowers, these changes being linked to increasing specialisation in pollinators.
Coronariae is a term used historically to refer to a group of flowering plants, generally including the lilies (Liliaceae), and later replaced by the order Liliales. First used in the 17th century by John Ray, it referred to flowers used to insert in garlands. Coronariae soon came to be associated with Liliaceae in the Linnaean system. The term was abandoned at the end of the 19th century, being replaced with Liliiflorae and then Liliales.
