George Engelmann
George Engelmann, also known as Georg Engelmann, (2 February 1809 – 4 February 1884) was a German-American botanist. He was instrumental in describing the flora of the west of North America, then very poorly known to Europeans; he was particularly active in the Rocky Mountains and northern Mexico, one of his constant companions being another German-American, the botanical illustrator Paulus Roetter. Biography Origins George Engelmann was born in Frankfurt am Main, Germany, the oldest of thirteen children, nine of whom reached maturity. His father, Julius Bernhardt Engelmann, was a member of a family from which for several successive generations were chosen ministers for the Reformed Church at Bacharach-on-the-Rhine. Julius was a graduate of the University of Halle, and was also educated for the ministry, but he devoted his life to education. He established a school for young women in Frankfurt, which was rare at the time. George Engelmann's mother, Julie Antoinette, was the ...

Pierre Edmond Boissier
Pierre Edmond Boissier (25 May 1810 Geneva – 25 September 1885 Valeyres-sous-Rances) was a Swiss prominent botanist, explorer and mathematician. He was the son of Jacques Boissier (1784-1857) and Caroline Butini (1786-1836), daughter of Pierre Butini (1759-1838) a well-known physician and naturalist from Geneva. With his sister, Valérie Boissier (1813-1894), he received a strict education with lessons delivered in Italian and Latin. Edmond's interest in natural history stemmed from holidays in the company of his mother and his grandfather, Pierre Butini at Valeyres-sous-Rances. His hikes in the Jura and the Alps laid the foundation of his zest for later exploration and adventure. He attended a course at the Academy of Geneva given by Augustin Pyramus de Candolle. Edmond Boissier collected extensively in Europe, North Africa and western Asia, on occasion accompanied by his daughter, Caroline Barbey-Boissier (1847-1918) and her husband, William Barbey (1842-1914), who coll ...

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] |
Spurge
''Euphorbia'' is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae. "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae (in deference to the type genus), not just to members of the genus. Euphorbias range from tiny annual plants to large and long-lived trees. The genus has roughly 2,000 members, making it one of the largest genera of flowering plants. It also has one of the largest ranges of chromosome counts, along with ''Rumex'' and ''Senecio''. ''Euphorbia antiquorum'' is the type species for the genus ''Euphorbia''. It was first described by Carl Linnaeus in 1753 in ''Species Plantarum''. Some euphorbias are widely available commercially, such as poinsettias at Christmas. Some are commonly cultivated as ornamentals, or collected and highly valued for the aesthetic appearance of their unique floral structures, such as the crown of thorns plant (''Euphorbia milii''). ...

Euphorbiaceae
Euphorbiaceae, the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of a genus in the family. Most spurges, such as '' Euphorbia paralias'', are herbs, but some, especially in the tropics, are shrubs or trees, such as '' Hevea brasiliensis''. Some, such as ''Euphorbia canariensis'', are succulent and resemble cacti because of convergent evolution. This family has a cosmopolitan global distribution. The greatest diversity of species is in the tropics, however, the Euphorbiaceae also have many species in nontropical areas of all continents except Antarctica. Description The leaves are alternate, seldom opposite, with stipules. They are mainly simple, but where compound, are always palmate, never pinnate. Stipules may be reduced to hairs, glands, or spines, or in succulent species are sometimes absent. The plants can be monoecious or dioecious. The radially symmetrical flowers are unise ...

Cyathium
A cyathium (plural: cyathia) is one of the specialised pseudanthia ("false flowers") forming the inflorescence of plants in the genus '' Euphorbia'' (Euphorbiaceae). A cyathium consists of: * Five (rarely four) bracteoles. These are small, united bracts, which form a cup-like involucre. Their upper tips are free and in the beginning cover the opening of the involucre (like the shutter of a camera). These alternate with: * Five (1 to 10) nectar glands, which are sometimes fused. * One extremely reduced female flower standing in the centre at the base of the involucre, consisting of an ovary on a short stem with pistil, and surrounded by: * Five groups (one group at the base of each bracteole) of extremely reduced male flowers, which each consist of a single anther on a stem. The flower-like characteristics of the cyathia are underlined by brightly coloured nectar glands and often by petal-like appendages to the nectar glands, or brightly coloured, petal-like bracts positione ...

CITES
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working lang ...
