Corydalis Nobilis
''Corydalis nobilis'', the Siberian corydalis, is a perennial plant native to Siberia, Xinjiang and Kazakhstan. It was introduced to Europe by Linnaeus, who had asked his friend Erich Laxmann for seeds of '' Lamprocapnos spectabilis'' (old-fashioned bleeding heart), but was sent seeds of ''C. nobilis'' instead. Both ''Lamprocampnos'' and '' Corydalis'' are members of the family Papaveraceae, with seeds having an attached elaiosome that makes them attractive to ants, which disperse the seeds. Description ''C. nobilis'' bears its compact cymose inflorescence on a stem that can be as tall as 50 cm. The stem is upright. Leaves are pinnate. Its flowers are yellow or orange; inner petals have dark violet at the top. The individual flowers resemble small snapdragons. The seeds of ''C. nobilis'' typically have elaiosomes (a fatty body attached to the seed but not part of it, which can be eaten by ants without harming the seed within.) Seeds of ''C. nobilis'' are dispersed by ants, ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), 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; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ...

Cyme (botany)
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Linnaeus Hammarby
Linnaeus's Hammarby ( sv, Linnés Hammarby) is a historic house museum and mansion, and one of three botanical gardens belonging to Uppsala University, located in Sweden. It is situated about 10 km south-east of Uppsala. Carl Linnaeus The manor house Hammarby was the former summer home of Carl Linnaeus and his family. Carl Linnaeus was a scientist and professor at Uppsala University. In 1762 Linnaeus bought the small estate of Hammarby in order to spend his holidays in a quiet place. Buildings The main house of Linnaeus has two floors, an attic and a cellar under part of the house. The house is constructed of horizontal logs. Inside the house, the old wallpaper is distinguished, with flower design in dark red, gold and white. It was probably made c. 1880. There are two other buildings in the compound. The east wing building housed the bakehouse and brewery. The west wing building probably housed the estate's staff and workers. Museum The Linnaeus's Hammarby is a hist ...

Altai Range
The Altai Mountains (), also spelled Altay Mountains, are a mountain range in Central and East Asia, where Russia, China, Mongolia and Kazakhstan converge, and where the rivers Irtysh and Ob have their headwaters. The massif merges with the Sayan Mountains in the northeast, and gradually becomes lower in the southeast, where it merges into the high plateau of the Gobi Desert. It spans from about 45° to 52° N and from about 84° to 99° E. The region is inhabited by a sparse but ethnically diverse population, including Russians, Kazakhs, Altais, Mongols and Volga Germans, though predominantly represented by indigenous ethnic minorities of semi-nomadic stock. The local economy is based on bovine, sheep, horse husbandry, hunting, agriculture, forestry, and mining. The Altaic language family takes its name from this mountain range. Etymology and modern names ''Altai'' is derived from underlying form *''altañ'' "gold, golden" (compare Old Turkic 𐰞𐱃𐰆𐰣 ''altu ...

Fumariaceae
Fumarioideae is a subfamily of the family Papaveraceae (the poppy family). It was formerly treated as a separate family, the Fumariaceae (the fumitory, fumewort or bleeding-heart family). It consists of about 575 species of herbaceous plants in 20 genera, native to the Northern Hemisphere and South Africa. The largest genus is '' Corydalis'' (with 470 species). Description Flower shape Plants in the fumitory subfamily are easily recognised by their peculiar flowers with two dissimilar pairs of petals. One or both of the outer petals is usually spurred, and the inner petals are connected at tip. There are two types of flowers. A given genus has one type or the other. ''Dicentra'' has flowers with two planes of symmetry, and '' Corydalis'' has flowers with one plane of symmetry (zygomorphic). Leaves Most species have compound leaves. Taxonomy The APG IV system of 2016 (unchanged from the earlier 1998 APG system, the 2003 APG II system, and the APG III system of 2009) includes t ...

Myrmecochory
Myrmecochory ( (sometimes myrmechory); from grc, μύρμηξ, mýrmēks ("ant") and ''khoreíā'' ("circular dance") is seed dispersal by ants, an ecologically significant ant–plant interaction with worldwide distribution. Most myrmecochorous plants produce seeds with elaiosomes, a term encompassing various external appendages or "food bodies" rich in lipids, amino acids, or other nutrients that are attractive to ants. The seed with its attached elaiosome is collectively known as a diaspore. Seed dispersal by ants is typically accomplished when foraging workers carry diaspores back to the ant colony, after which the elaiosome is removed or fed directly to ant larvae. Once the elaiosome is consumed, the seed is usually discarded in underground middens or ejected from the nest. Although diaspores are seldom distributed far from the parent plant, myrmecochores also benefit from this predominantly mutualistic interaction through dispersal to favourable locations for germina ...

Antirrhinum
''Antirrhinum'' is a genus of plants commonly known as dragon flowers, snapdragons and dog flower because of the flowers' fancied resemblance to the face of a dragon that opens and closes its mouth when laterally squeezed. They are native to rocky areas of Europe, the United States, Canada, and North Africa. It is widely used as an ornamental plant in borders and as a cut flower. Description The Antirrhinum is morphologically diverse, particularly the New World group (''Saerorhinum''). The genus is characterized by personate flowers with an inferior gibbous corolla. Taxonomy ''Antirrhinum'' used to be treated within the family Scrophulariaceae, but studies of DNA sequences have led to its inclusion in a vastly enlarged family Plantaginaceae, within the tribe Antirrhineae. Circumscription The taxonomy of this genus is complex and not yet fully resolved at present. In particular the exact circumscription of the genus, especially the inclusion of the New World species (Sa ...

Pinnate
Pinnation (also called pennation) is the arrangement of feather-like or multi-divided features arising from both sides of a common axis. Pinnation occurs in biological morphology, in crystals, such as some forms of ice or metal crystals, and in patterns of erosion or stream beds. The term derives from the Latin word ''pinna'' meaning "feather", "wing", or "fin". A similar concept is "pectination," which is a comb-like arrangement of parts (arising from one side of an axis only). Pinnation is commonly referred to in contrast to "palmation," in which the parts or structures radiate out from a common point. The terms "pinnation" and "pennation" are cognate, and although they are sometimes used distinctly, there is no consistent difference in the meaning or usage of the two words.Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 Plants Botanically, pinnation is an arrangement of discr ...

Christiaan Hendrik Persoon
Christiaan Hendrik Persoon (1 February 1761 – 16 November 1836) was a German mycologist who made additions to Linnaeus' mushroom taxonomy. Early life Persoon was born in South Africa at the Cape of Good Hope, the third child of an immigrant Pomeranian father and Dutch mother. His mother died soon after he was born; at the age of thirteen his father (who died a year later) sent him to Europe for his education. Education Initially studying theology at Halle, at age 22 (in 1784) Persoon switched to medicine at Leiden and Göttingen. He received a doctorate from the "Kaiserlich-Leopoldinisch-Carolinische Deutsche Akademie der Naturforscher" in 1799. Later years He moved to Paris in 1802, where he spent the rest of his life, renting an upper floor of a house in a poor part of town. He was apparently unemployed, unmarried, poverty-stricken and a recluse, although he corresponded with botanists throughout Europe. Because of his financial difficulties, Persoon agreed to dona ...

Elaiosome
Elaiosomes ( grc, ἔλαιον ''élaion'' "oil" + ''sóma'' "body") are fleshy structures that are attached to the seeds of many plant species. The elaiosome is rich in lipids and proteins, and may be variously shaped. Many plants have elaiosomes that attract ants, which take the seed to their nest and feed the elaiosome to their larvae. After the larvae have consumed the elaiosome, the ants take the seed to their waste disposal area, which is rich in nutrients from the ant frass and dead bodies, where the seeds germinate. This type of seed dispersal is termed myrmecochory from the Greek "ant" (myrmex) and "circular dance" (khoreíā). This type of symbiotic relationship appears to be mutualistic, more specifically dispersive mutualism according to Ricklefs, R.E. (2001), as the plant benefits because its seeds are dispersed to favorable germination sites, and also because it is planted (carried underground) by the ants. Elaiosomes develop in various ways either from seed ti ...

Papaveraceae
The Papaveraceae are an economically important family of about 42 genera and approximately 775 known species of flowering plants in the order Ranunculales, informally known as the poppy family. The family is cosmopolitan, occurring in temperate and subtropical climates (mostly in the northern hemisphere), but almost unknown in the tropics. Most are herbaceous plants, but a few are shrubs and small trees. The family currently includes two groups that have been considered to be separate families: Fumariaceae and Pteridophyllaceae. Description The plants may be annual, biennial, or perennial. Usually herbaceous, a few species form shrubs or evergreen trees. They are lactiferous, producing latex, which may be milky or watery, coloured or plain. All parts contain a well-developed duct system (these ducts are called "laticifers"), producing a milky latex, a watery white, yellow or red juice. The simple leaves are alternate or sometimes whorled. They have petioles and are not enc ...
