Paeonia Corsica
''Paeonia corsica'' is a perennial herbaceous plant of high that belongs to the peonies. It naturally occurs on Corsica, Sardinia, on the Ionian islands and in western Greece. It has hairless green to purple stems, and the lower leaves consist mostly of nine leaflets with undersides which may carry felty hairs or are hairless. Its flowers have pink petals and purple filaments. Its vernacular name in Italian is peonia Corsa, and in French pivoine de Corse, both meaning "Corsican peony". Description The Corsican peony is a diploid species (2n=10). It is a perennial herbaceous photosynthesising plant, which dies down in the autumn and reappears above the surface in spring. It flowers in April and May. Fruits may open from August onwards. Root, stem and leaves This peony has grey to brown roots shaped like carrots, about in diameter near the attachment of the stems and gradually becoming narrower towards their tips. It has stiff, erect, hairless, green to purple stems of high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franz Sieber
Franz Wilhelm Sieber (30 March 1789 – 17 December 1844), was a botanist and collector who travelled to Europe, the Middle East, Southern Africa and Australia. Early life Franz Sieber was born in Prague, Bohemia on 30 March 1789. After 5 years of study at the Gymnasium, endowed with a considerable talent for the graphic arts, he studied architecture, switched to engineering and finally settled on natural history, in particular botany. Expeditions He made several collecting trips to Italy, Crete, Greece, Egypt and Palestine followed by a two-year-long expedition to Australia, Mauritius and South Africa, collecting not only plants, but also animals, art and ethnographic objects. He spent seven months in Sydney (then more usually called Port Jackson) from 1 June 1823 until December 1823 where he collected 645 local plant specimens. He never reached the Western hemisphere (in contradistinction to Friedrich Wilhelm Sieber, an employee of Johann Centurius Hoffmannsegg) ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Ernst Huth
Ernst Huth (27 December 1845, Potsdam – 5 August 1897) was a German naturalist and botanist. He studied mathematics and natural sciences in Berlin, later working as a secondary school teacher in Frankfurt an der Oder. Beginning in 1883 he published the ''Monatliche Mittheilungen des Naturwissenschaftlichen Vereins Regierungsbezirkes Frankfurt'', in which he was the author of numerous scientific articles. He is known for his treatment of the botanical family Ranunculaceae, of which he was the taxonomic author of many species, especially plants within the genus ''Delphinium''.

Philip Barker-Webb
Philip Barker Webb (10 July 1793 – 31 August 1854) was an English botanist. Life Webb was born to a wealthy, aristocratic family; his father was the lord of the manors of Witley and Milford, Surrey, Milford, in Surrey, England. Webb was educated at Harrow School and Christ Church, Oxford. He collected plants in Italy, Spain, and Portugal, and was the first person to collect in the Tetuan Mountains of Morocco. En route to Brazil he made what was intended to be a brief visit to the Canary Islands, but he stayed for a considerable time, returning after his Brazil expedition. The results can be seen in the nine-volume ''Natural History of the Canary Islands, Histoire Naturelle des Iles Canaries'' (''Natural History of the Canary Islands''), which he co-authored with Sabin Berthelot. In company with Berthelot, who had lived on the islands for some time, Webb collected specimens on the islands between 1828 and 1830. The text of ''Histoire Naturelle des Iles Canaries'' took 20&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antonino De Bivona-Bernardi
Antonino (or ''Antonius'') de Bivona-Bernardi (1774 or 24 October 1778 – 1837) was a Sicilian botanist, bryologist and phycologist. He was born in Messina, but was orphaned as a child, and moved to Palermo with the uncle who adopted him. He originally pursued law, but changed his studies to the natural sciences and studied botany under Giuseppe Tineo, director of the Palermo Botanical Garden. After graduating, he travelled to Naples and elsewhere in Italy, making the acquaintance of scientists such as Michele Tenore and Vincenzo Petagna. Professor Francesco Ferrara of Palermo entered a public dispute about deposits had found in Sicily, which he (Antonino), had discovered and thought were fossils. He returned to Palermo upon the death of his uncle, and began to publish botanical works that had great impact in Italy and Europe. He founded the scientific journal "L'Iride" ("The Iris") and obtained the post of Inspector-General of Waters and Forests, but died in Palermo during th ...

Ernest Cosson
Ernest Saint-Charles Cosson (22 July 1819 – 31 December 1889) was a French botanist born in Paris. Cosson is known for his botanical research in North Africa, and during his career he participated in eight trips to Algeria. In several of these he was accompanied by Henri-René Le Tourneux de la Perraudière (1831-1861), whom he honoured in the naming of several species and genera (e.g., ''Perralderia'', ''Galium perralderii''). In 1863 he was elected president of the ''Société botanique de France'', and from 1873 to 1889, he was a member of the ''Académie des sciences''. In 1882 Jules Ferry, as Minister of Public Instruction, decided to create a mission to explore the Regency of Tunisia. The expedition was headed by Cosson and included the botanist Napoléon Doumet-Adanson and other naturalists. In 1884 a geological section under Georges Rolland was added to the Tunisian Scientific Exploration Mission. Rolland was assisted by Philippe Thomas from 1885 and by Georges Le Me ...

Paeonia Cambessedesii
''Paeonia cambessedesii'' is a Perennial plant, perennial Herbaceous plant, herbaceous species of peony about 45 cm high. It has pink flowers.

Hypocotyl
The hypocotyl (short for "hypocotyledonous stem", meaning "below seed leaf") is the stem of a germinating seedling, found below the cotyledons (seed leaves) and above the radicle (root). Eudicots As the plant embryo grows at germination, it sends out a shoot called a radicle that becomes the primary root, and then penetrates down into the soil. After emergence of the radicle, the hypocotyl emerges and lifts the growing tip (usually including the seed coat) above the ground, bearing the embryonic leaves (called cotyledons), and the plumule that gives rise to the first true leaves. The hypocotyl is the primary organ of extension of the young plant and develops into the stem. Monocots The early development of a monocot seedling like cereals and other grasses is somewhat different. A structure called the coleoptile, essentially a part of the ''cotyledon'', protects the young stem and plumule as growth pushes them up through the soil. A mesocotyl—that part of the young plant that li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
