The Pyrenees is a range of mountains in southwest Europe that forms a natural border between Spain and France. Reaching a height of 3,404 metres altitude at the peak of Aneto, the range separates the Iberian Peninsula from the rest of continental Europe, extends for about 491 km from the Bay of Biscay to the Mediterranean Sea. For the most part, the main crest forms a divide between Spain and France, with the microstate of Andorra sandwiched in between; the Principality of Catalonia alongside with the Kingdom of Aragon in the Crown of Aragon and the Kingdom of Navarre have extended on both sides of the mountain range, with smaller northern portions now in France and larger southern parts now in Spain. In Greek mythology, Pyrene is a princess; the Greek historian Herodotus says. According to Silius Italicus, she was the virgin daughter of Bebryx, a king in Mediterranean Gaul by whom the hero Hercules was given hospitality during his quest to steal the cattle of Geryon during his famous Labours.
Hercules, characteristically drunk and lustful, violates the sacred code of hospitality and rapes his host's daughter. Pyrene runs away to the woods, afraid that her father will be angry. Alone, she pours out her story to the trees, attracting the attention of wild beasts who tear her to pieces. After his victory over Geryon, Hercules passes through the kingdom of Bebryx again, finding the girl's lacerated remains; as is the case in stories of this hero, the sober Hercules responds with heartbroken grief and remorse at the actions of his darker self, lays Pyrene to rest tenderly, demanding that the surrounding geography join in mourning and preserve her name: "struck by Herculean voice, the mountaintops shudder at the ridges. … The mountains hold on to the wept-over name through the ages." Pliny the Elder connects the story of Hercules and Pyrene to Lusitania, but rejects it as fabulosa fictional. Other classical sources derived the name from the Greek word for fire, Ancient Greek: πῦρ. According to Greek historian Diodorus Siculus "..in ancient times, we are told, certain herdsmen left a fire and the whole area of the mountains was consumed.
The Spanish Pyrenees are part of the following provinces, from east to west: Girona, Lleida, Huesca and Gipuzkoa. The French Pyrenees are part of the following départements, from east to west: Pyrénées-Orientales, Ariège, Haute-Garonne, Hautes-Pyrénées, Pyrénées-Atlantiques; the independent principality of Andorra is sandwiched in the eastern portion of the mountain range between the Spanish Pyrenees and French Pyrenees. Physiographically, the Pyrenees may be divided into three sections: the Atlantic, the Central, the Eastern Pyrenees. Together, they form a distinct physiographic province of the larger Alpine System division. In the Western Pyrenees, from the Basque mountains near the Bay of Biscay of the Atlantic Ocean, the average elevation increases from west to east; the Central Pyrenees extend eastward from the Somport pass to the Aran Valley, they include the highest summits of this range: Pico d'Aneto 3,404 metres in the Maladeta ridge, Pico Posets 3,375 metres, Monte Perdido 3,355 metres.
In the Eastern Pyrenees, with the exception of one break at the eastern extremity of the Pyrénées Ariègeoises in the Ariège area, the mean elevation is remarkably uniform until a sudden decline occurs in the easternmost portion of the chain known as the Albères. Most foothills of the Pyrenees are on the Spanish side, where there is a large and complex system of ranges stretching from Spanish Navarre, across northern Aragon and into Catalonia reaching the Mediterranean coast with summits reaching 2,600 m. At the eastern end on the southern side lies a distinct area known as the Sub-Pyrenees. On the French side the slopes of the main range descend abruptly and there are no foothills except in the Corbières Massif in the northeastern corner of the mountain system; the Pyrenees are older than the Alps: their sediments were first deposited in coastal basins during the Paleozoic and Mesozoic eras. Between 100 and 150 million years ago, during the Lower Cretaceous Period, the Bay of Biscay fanned out, pushing present-day Spain against France and applying intense compressional pressure to large layers of sedimentary rock.
The intense pressure and uplifting of the Earth's crust first affected the eastern part and moved progressively to the entire chain, culminating in the Eocene Epoch. The eastern part of the Pyrenees consists of granite and gneissose rocks, while in the western part the granite peaks are flanked by layers of limestone; the massive and unworn character of the chain comes from its abundance of granite, resistant to erosion, as well as weak glacial development. The upper parts of the Pyrenees contain low-relief surfaces forming a peneplain; this peneplain originated no earlier than in Late Miocene times. It formed at height as extensive sedimentation raised the local base
The eudicots, Eudicotidae or eudicotyledons are a clade of flowering plants, called tricolpates or non-magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots; the close relationships among flowering plants with tricolpate pollen grains was seen in morphological studies of shared derived characters. These plants have a distinct trait in their pollen grains of exhibiting three colpi or grooves paralleling the polar axis. Molecular evidence confirmed the genetic basis for the evolutionary relationships among flowering plants with tricolpate pollen grains and dicotyledonous traits; the term means "true dicotyledons", as it contains the majority of plants that have been considered dicots and have characteristics of the dicots. The term "eudicots" has subsequently been adopted in botany to refer to one of the two largest clades of angiosperms, monocots being the other.
The remaining angiosperms include magnoliids and what are sometimes referred to as basal angiosperms or paleodicots, but these terms have not been or adopted, as they do not refer to a monophyletic group. The other name for the eudicots is tricolpates, a name which refers to the grooved structure of the pollen. Members of the group have tricolpate pollen; these pollens have three or more pores set in furrows called colpi. In contrast, most of the other seed plants produce monosulcate pollen, with a single pore set in a differently oriented groove called the sulcus; the name "tricolpates" is preferred by some botanists to avoid confusion with the dicots, a nonmonophyletic group. Numerous familiar plants are eudicots, including many common food plants and ornamentals; some common and familiar eudicots include members of the sunflower family such as the common dandelion, the forget-me-not and other members of its family, buttercup and macadamia. Most leafy trees of midlatitudes belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, Ginkgo biloba, not an angiosperm.
The name "eudicots" is used in the APG system, of 1998, APG II system, of 2003, for classification of angiosperms. It is applied to a monophyletic group, which includes most of the dicots. "Tricolpate" is a synonym for the "Eudicot" monophyletic group, the "true dicotyledons". The number of pollen grain furrows or pores helps classify the flowering plants, with eudicots having three colpi, other groups having one sulcus. Pollen apertures are any modification of the wall of the pollen grain; these modifications include thinning and pores, they serve as an exit for the pollen contents and allow shrinking and swelling of the grain caused by changes in moisture content. The elongated apertures/ furrows in the pollen grain are called colpi, along with pores, are a chief criterion for identifying the pollen classes; the eudicots can be divided into two groups: the basal eudicots and the core eudicots. Basal eudicot is an informal name for a paraphyletic group; the core eudicots are a monophyletic group.
A 2010 study suggested the core eudicots can be divided into two clades, Gunnerales and a clade called "Pentapetalae", comprising all the remaining core eudicots. The Pentapetalae can be divided into three clades: Dilleniales superrosids consisting of Saxifragales and rosids superasterids consisting of Santalales, Berberidopsidales and asteridsThis division of the eudicots is shown in the following cladogram: The following is a more detailed breakdown according to APG IV, showing within each clade and orders: clade Eudicots order Ranunculales order Proteales order Trochodendrales order Buxales clade Core eudicots order Gunnerales order Dilleniales clade Superrosids order Saxifragales clade Rosids order Vitales clade Fabids order Fabales order Rosales order Fagales order Cucurbitales order Oxalidales order Malpighiales order Celastrales order Zygophyllales clade Malvids order Geraniales order Myrtales order Crossosomatales order Picramniales order Malvales order Brassicales order Huerteales order Sapindales clade Superasterids order Berberidopsidales order Santalales order Caryophyllales clade Asterids order Cornales order Ericales clade Campanulids order Aquifoliales order Asterales order Escalloniales order Bruniales order Apiales order Dipsacales order Paracryphiales clade Lamiids order Solanales order Lamiales order Vahliales order Gentianales order Boraginales order Garryales order Metteniusales order Icacinales Eudicots at the Encyclopedia of Life Eudicots, Tree of Life Web Project Dicots Plant Life Forms
The flowering plants known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 64 orders, 416 families 13,164 known genera and c. 369,000 known species. Like gymnosperms, angiosperms are seed-producing plants. However, they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, the production of fruits that contain the seeds. Etymologically, angiosperm means a plant; the term comes from the Greek words sperma. The ancestors of flowering plants diverged from gymnosperms in the Triassic Period, 245 to 202 million years ago, the first flowering plants are known from 160 mya, they diversified extensively during the Early Cretaceous, became widespread by 120 mya, replaced conifers as the dominant trees from 100 to 60 mya. Angiosperms differ from other seed plants in several ways, described in the table below; these distinguishing characteristics taken together have made the angiosperms the most diverse and numerous land plants and the most commercially important group to humans.
Angiosperm stems are made up of seven layers. The amount and complexity of tissue-formation in flowering plants exceeds that of gymnosperms; the vascular bundles of the stem are arranged such that the phloem form concentric rings. In the dicotyledons, the bundles in the young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium. By the formation of a layer of cambium between the bundles, a complete ring is formed, a regular periodical increase in thickness results from the development of xylem on the inside and phloem on the outside; the soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Owing to differences in the character of the elements produced at the beginning and end of the season, the wood is marked out in transverse section into concentric rings, one for each season of growth, called annual rings.
Among the monocotyledons, the bundles are more numerous in the young stem and are scattered through the ground tissue. They once formed the stem increases in diameter only in exceptional cases; the characteristic feature of angiosperms is the flower. Flowers show remarkable variation in form and elaboration, provide the most trustworthy external characteristics for establishing relationships among angiosperm species; the function of the flower is to ensure fertilization of the ovule and development of fruit containing seeds. The floral apparatus may arise terminally from the axil of a leaf; as in violets, a flower arises singly in the axil of an ordinary foliage-leaf. More the flower-bearing portion of the plant is distinguished from the foliage-bearing or vegetative portion, forms a more or less elaborate branch-system called an inflorescence. There are two kinds of reproductive cells produced by flowers. Microspores, which will divide to become pollen grains, are the "male" cells and are borne in the stamens.
The "female" cells called megaspores, which will divide to become the egg cell, are contained in the ovule and enclosed in the carpel. The flower may consist only of these parts, as in willow, where each flower comprises only a few stamens or two carpels. Other structures are present and serve to protect the sporophylls and to form an envelope attractive to pollinators; the individual members of these surrounding structures are known as petals. The outer series is green and leaf-like, functions to protect the rest of the flower the bud; the inner series is, in general, white or brightly colored, is more delicate in structure. It functions to attract bird pollinators. Attraction is effected by color and nectar, which may be secreted in some part of the flower; the characteristics that attract pollinators account for the popularity of flowers and flowering plants among humans. While the majority of flowers are perfect or hermaphrodite, flowering plants have developed numerous morphological and physiological mechanisms to reduce or prevent self-fertilization.
Heteromorphic flowers have short carpels and long stamens, or vice versa, so animal pollinators cannot transfer pollen to the pistil. Homomorphic flowers may employ a biochemical mechanism called self-incompatibility to discriminate between self and non-self pollen grains. In other species, the male and female parts are morphologically separated, developing on different flowers; the botanical term "Angiosperm", from the Ancient Greek αγγείον, angeíon and σπέρμα, was coined in the form Angiospermae by Paul Hermann in 1690, as the name of one of his primary divisions of the plant kingdom. This included flowering plants possessing seeds enclosed in capsules, distinguished from his Gymnospermae, or flowering plants with achenial or schizo-carpic fruits, the whole fruit or each of its pieces being here regarded as a seed and naked; the term and its antonym were maintained by Carl Linnaeus with the same sense, but with restricted application, in the names of the orders of his class Didynamia. Its use with any
In scientific nomenclature, a synonym is a scientific name that applies to a taxon that goes by a different scientific name, although the term is used somewhat differently in the zoological code of nomenclature. For example, Linnaeus was the first to give a scientific name to the Norway spruce, which he called Pinus abies; this name is no longer in use: it is now a synonym of the current scientific name, Picea abies. Unlike synonyms in other contexts, in taxonomy a synonym is not interchangeable with the name of which it is a synonym. In taxonomy, synonyms have a different status. For any taxon with a particular circumscription and rank, only one scientific name is considered to be the correct one at any given time. A synonym cannot exist in isolation: it is always an alternative to a different scientific name. Given that the correct name of a taxon depends on the taxonomic viewpoint used a name, one taxonomist's synonym may be another taxonomist's correct name. Synonyms may arise whenever the same taxon is named more than once, independently.
They may arise when existing taxa are changed, as when two taxa are joined to become one, a species is moved to a different genus, a variety is moved to a different species, etc. Synonyms come about when the codes of nomenclature change, so that older names are no longer acceptable. To the general user of scientific names, in fields such as agriculture, ecology, general science, etc. A synonym is a name, used as the correct scientific name but, displaced by another scientific name, now regarded as correct, thus Oxford Dictionaries Online defines the term as "a taxonomic name which has the same application as another one, superseded and is no longer valid." In handbooks and general texts, it is useful to have synonyms mentioned as such after the current scientific name, so as to avoid confusion. For example, if the much advertised name change should go through and the scientific name of the fruit fly were changed to Sophophora melanogaster, it would be helpful if any mention of this name was accompanied by "".
Synonyms used in this way may not always meet the strict definitions of the term "synonym" in the formal rules of nomenclature which govern scientific names. Changes of scientific name have two causes: they may be taxonomic or nomenclatural. A name change may be caused by changes in the circumscription, position or rank of a taxon, representing a change in taxonomic, scientific insight. A name change may be due to purely nomenclatural reasons, that is, based on the rules of nomenclature. Speaking in general, name changes for nomenclatural reasons have become less frequent over time as the rules of nomenclature allow for names to be conserved, so as to promote stability of scientific names. In zoological nomenclature, codified in the International Code of Zoological Nomenclature, synonyms are different scientific names of the same taxonomic rank that pertain to that same taxon. For example, a particular species could, over time, have had two or more species-rank names published for it, while the same is applicable at higher ranks such as genera, orders, etc.
In each case, the earliest published name is called the senior synonym, while the name is the junior synonym. In the case where two names for the same taxon have been published the valid name is selected accorded to the principle of the first reviser such that, for example, of the names Strix scandiaca and Strix noctua, both published by Linnaeus in the same work at the same date for the taxon now determined to be the snowy owl, the epithet scandiaca has been selected as the valid name, with noctua becoming the junior synonym. One basic principle of zoological nomenclature is that the earliest published name, the senior synonym, by default takes precedence in naming rights and therefore, unless other restrictions interfere, must be used for the taxon. However, junior synonyms are still important to document, because if the earliest name cannot be used the next available junior synonym must be used for the taxon. For other purposes, if a researcher is interested in consulting or compiling all known information regarding a taxon, some of this may well have been published under names now regarded as outdated and so it is again useful to know a list of historic synonyms which may have been used for a given current taxon name.
Objective synonyms refer to taxa with same rank. This may be species-group taxa of the same rank with the same type specimen, genus-group taxa of the same rank with the same type species or if their type species are themselves objective synonyms, of family-group taxa with the same type genus, etc. In the case of subjective synonyms, there is no such shared type, so the synonymy is open to taxonomic judgement, meaning that th
Adonis is a genus of about 20–30 species of flowering plants of the crowfoot family, native to Europe and Asia. The species grow with feathery, finely divided leaves, their flowers have 5 -- 30 petals. The Autumn Adonis, pheasant's-eye, has flowers with bright red petals; the generic name Adonis refers to the mythic character Adonis, a lover of the goddess Aphrodite or Venus. According to the Metamorphoses of Ovid the anemone of the family Ranunculaceae, was created when Venus sprinkled nectar on his blood. Adonis aestivalis - summer pheasant's-eye Adonis aleppica Adonis amurensis - Far East Amur adonis Adonis annua - pheasant's-eye or blooddrops Adonis bobroviana Adonis chrysocyathus Adonis coerulea Adonis cyllenea Adonis davidii Adonis dentata Adonis distorta Adonis flammea Adonis microcarpa Adonis nepalensis Adonis palaestina Adonis pyrenaica from the Pyrenees, has thick foliage and large golden yellow flowers in early summer. Adonis ramosa Adonis sibirica Adonis sutchuenensis Adonis tianschanica Adonis vernalis - spring pheasant's-eye Adonis volgensis They are cultivated for use in gardens, have been introduced to North America.
Adonis spp. contain poisonous chemicals similar to those found in many other genera in the Ranunculaceae. Herbalism Media related to Adonis at Wikimedia Commons Flora of China: Adonis USDA Plants Profile: Adonis
Ranunculaceae is a family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide. The largest genera are Ranunculus, Thalictrum and Aconitum. Ranunculaceae are herbaceous annuals or perennials, but some woody climbers or shrubs. Most members of the family have bisexual flowers which can be inconspicuous. Flowers may be solitary, but are found aggregated in cymes, panicles, or spikes; the flowers are radially symmetrical but are bilaterally symmetrical in the genera Aconitum and Delphinium. The sepals, petals and carpels are all free, the outer flower segments number four or five; the outer stamens may be modified to produce only nectar, as in Delphinium. In some genera, such as Thalictrum the sepals are colorful and appear petal-like and the petals can be inconspicuous or absent; the stems are unarmed. The leaves are variable. Most species have both basal and cauline leaves, which are compound or lobed but can be simple, they are alternate, or opposite or whorled. Many species the perennials form rhizomes that develop new roots each year.
Ficaria verna can reproduce vegetatively by means of root tubers produced in the leaf axils. Some members of the genus Thalictrum utilize anemophily. Flowers of the entomophilous genus Papaver of the Ranunculales order, produce only pollen; until it was believed that the species of the genus Anemone lack nectar. The fruits are most free, unfused achenes or follicles, but a berry in Actaea. Ranunculaceae contain protoanemonin, toxic to humans and animals. Other poisonous or toxic compounds and glycosides, are common. Takhtajan included the Ranunculaceae as the only family in the Ranunculales which he placed in a subclass, the Ranunculidae, instead of a superorder. Thorn placed the Ranunculaceae in the Berberidales, an order within the Superorder Magnolianae. Earlier Cronquist in 1981 included the Ranunculaceae along with seven other families in the Rancunculales, included in the Magnoliidae, which he regarded as a subclass. David, placed the Ranuculaceae, together with the Eupteleaceae, Menispermaceae and Papaveraceae in the Ranunculales, the only order in the superorder Ranunculanae.
This follows the work of the Angiosperm Phylogeny Group. The family Ranunculaceae sensu stricto is one of seven families included in the order Ranunculales within the eudicots according to the Angiosperm Phylogeny Group classification; the family is monophyletic with Glaucidium as sister to the remaining genera. This phylogeny is illustrated in the APG Poster. Early subdivisions of the family, such as Adanson divided it based on one-seeded or many-seeded fruit. Prantl envisaged three tribes, Paeonieae and Anemoneae with Paeonia and Hydrastis forming Paeoniaae. By the twentieth century Langlet used chromosome types to create two subfamilies and Thalictroideae. In 1966 Tamura further developed Langlet's system by adding floral characteristics with six subfamilies. Paeonia was placed in its own family of Paeoniaceae. Other genera included in Ranunculaceae include Circaeaster, placed in its own family Circaeasteraceae. Tamura's complete system was structured. Adonideae Kunth Anemoneae DC. Ranunculeae DC.

Kosuge Dichocarpeae Tamura & K. Kosuge Isopyreae Schrödinger Subfamily Thalictroideae Subfamily HydrastidoideaeThe genus Glaucidium, having been moved to its own family, has since been restored to Ranuculaceae; when subjected to molecular phylogenetic analysis only Thalictroideae is monophyletic. The position of Glaucidium and some of its unique morphological characteristics prompted Stevens to suggest that it be given subfamilial rank as the monotypic Glaucidioideae. Hydrastis has been assigned to subfamily Hydrastidoideae. Both genera are represented by a single species, Glaucidium palmatum and Hydrastis canadense respectively; the relationships between the genera suggest the existence of three major clades corresponding to Coptidoideae and Ranunculoideae. The latter is the largest with four subclades. Of these C corresponds to D to Cimicifugae and E to Ranunculoideae.
Wang and colleagues proposed a new classification with five subfamilies, further subdividing Ranunculoideae into ten tribes. The relationship between the subfamilies is shown in the cladogram; the other genera belong to Ranunculoideae. Kingdonia had been included by Tamura in Anemoneae, but is now added
Augustin Pyramus de Candolle
Augustin Pyramus de Candolle spelled Augustin Pyrame de Candolle was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at an herbarium. Within a couple of years de Candolle had established a new genus, 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 contributed to related fields such as phytogeography, paleontology, medical botany, economic botany. 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. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggesting that an internal biological clock exists. Though many scientists doubted de Candolle's findings, experiments over a century demonstrated that ″the internal biological clock″ indeed exists.
Candolle's descendants continued his work on plant classification. Alphonse de Candolle and Casimir Pyrame de Candolle contributed to the Prodromus Systematis Naturalis Regni Vegetabilis, a catalog of plants begun by Augustin Pyramus de Candolle. Augustin Pyramus de Candolle was born on 4 February 1778 in Geneva, Switzerland, to Augustin de Candolle, a former official, his wife, Louise Eléonore Brière, his family descended from one of the ancient families of Provence in France, but relocated to Geneva at the end of the 16th century to escape religious persecution. At age seven de Candolle contracted of a severe case of hydrocephalus, which affected his childhood, he is said to have had great aptitude for learning, distinguishing himself in school with his rapid acquisition of knowledge in classical and general literature and his ability to write fine poetry. In 1794, he began his scientific studies at the Collège Calvin, where he studied under Jean Pierre Étienne Vaucher, who inspired de Candolle to make botanical science the chief pursuit of his life.
He spent four years at the Geneva Academy, studying science and law according to his father's wishes. In 1798, he moved to Paris, his botanical career formally began with the help of René Louiche Desfontaines, who recommended de Candolle for work in the herbarium of Charles Louis L'Héritier de Brutelle during the summer of 1798. The position elevated de Candolle's reputation and led to valuable instruction from Desfontaines himself. De Candolle established his first genus, Senebiera, in 1799.de Candolle's first books, Plantarum historia succulentarum and Astragalogia, brought him to the notice of Georges Cuvier and Jean-Baptiste Lamarck. de Candolle, with Cuvier's approval, acted as deputy at the Collège de France in 1802. Lamarck entrusted him with the publication of the third edition of the Flore française, in the introduction entitled Principes élémentaires de botanique, de Candolle proposed a natural method of plant classification as opposed to the artificial Linnaean method; the premise of de Candolle's method is.
In 1804, de Candolle published his Essai sur les propriétés médicales des plantes and was granted a doctor of medicine degree by the medical faculty of Paris. Two years he published Synopsis plantarum in flora Gallica descriptarum. de Candolle spent the next six summers making a botanical and agricultural survey of France at the request of the French government, published in 1813. In 1807 he was appointed professor of botany in the medical faculty of the University of Montpellier, where he would become the first chair of botany in 1810, his teaching at the University of Montpellier consisted of field classes attended by 200–300 students, starting at 5:00 am and finishing at 7:00 pm. While in Montpellier, de Candolle published his Théorie élémentaire de la botanique, which introduced a new classification system and the word taxonomy. Candolle moved back to Geneva in 1816 and in the following year was invited by the government of the Canton of Geneva to fill the newly created chair of natural history.
De Candolle spent the rest of his life in an attempt to elaborate and complete his natural system of botanical classification. De Candolle published initial work in his Regni vegetabillis systema naturale, but after two volumes he realized he could not complete the project on such a large scale, he began his less extensive Prodromus Systematis Naturalis Regni Vegetabilis in 1824. However, he was able to finish two-thirds of the whole. So, he was able to characterize over one hundred families of plants, helping to lay the empirical basis of general botany. Although de Candolle's main focus was botany, throughout his career he dabbled in fields related to botany, such as phytogeography, paleontology, medical botany, economic botany. In 1827 he was elected an associated member of the Royal Institute of the Netherlands. Augustin de Candolle was the first of four generations of botanists in the de Candolle dynasty, his son, Alphonse de Candolle, whom he fathered with his wife, Mademoiselle Torras succeeded to his father's chair in botany and continued the Prodromus.
Casimir Pyrame de Candolle, Augustin de Candolle's grandson contributed to the Prodromus through his detailed, extensive research and characterization of the Piperaceae family of plants. Augustin de Candolle's great-grandson, Richard Émile Augustin de Candolle
