Fool's-water-cress
''Helosciadium nodiflorum'' (synonym: ''Apium nodiflorum''), fool's watercress, is a flowering plant found in ditches or streams, as well as fresh and brackish-water wetlands native to western Europe. It is not poisonous to humans but it could be easily confused with the allegedly poisonous lesser water parsnip. Description ''Helosciadium nodiflorum'' is a low-growing or prostrate hairless perennial up to 1 m tall, with a thick, hollow, faintly ridged stem which, when lying down (procumbent) produces roots at the nodes. It has glossy pinnate leaves, each of which has 4-6 opposite pairs of toothed, oval to lanceolate leaflets that are slightly paler green on the undersides. There are ridges at the nodes of the leaflets which are often paler than the rhachis and look like rings. (Note, this is different from lesser water-parsnip, which has a ring on the petiole.) The petioles are hollow with a distinctive single groove on upper surface, and may be streaked with red/purple lines; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mariano Lagasca
Mariano Lagasca y Segura (1776–1839), also known as Mariano la Gasca, was a Spanish botanist, writer and doctor. He was the director of the ''Real JardÃn Botánico de Madrid'' (Royal Botanical Garden of Madrid).

Helosciadium Bermejoi
''Helosciadium bermejoi'', synonym ''Apium bermejoi'', is a critically endangered species of flowering plant in the family Apiaceae. Taxonomy It is not closely related to the wild form of celery, ''A. graveolens'', being more properly placed in the genus '' Helosciadium'' in the tribe Oenantheae. Distribution ''H. bermejoi'' is endemic to Menorca in the Balearic Islands of Spain, and the total population is now restricted to a single locality in the northeast part of the island. Across the two populations at this spot, there are fewer than a hundred individuals surviving. Ecology Its natural habitat is Mediterranean-type shrubby vegetation, known as matorral. Conservation It was classified as ' critically endangered' in the IUCN Red List in 2006. In the European Union it has been designated as a 'priority species' under Annex II of the Habitats Directive since 1992, which means areas in which it occurs can be declared Special Areas of Conservation, ''if'' these areas belong ...

Flora Of The Arabian Peninsula
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea ...

Freshwater Plants
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water i ...

Apium
''Apium'' (including celery and the marshworts) is a genus of about 20 species of flowering plants in the family Apiaceae, with a subcosmopolitan distribution in Europe, Asia, Africa, South America and Australia. They are medium to tall biennials or perennials growing up to 1 m high in the wet soil of marshes and salt marshes, and have pinnate to bipinnate leaves and small white flowers in compound umbels. Some species are edible, notably ''Apium graveolens'', which includes the commercially important vegetables celery, celeriac and Chinese celery. ''Apium bermejoi'' from the island of Menorca is one of the rarest plants in Europe, with fewer than 100 individuals left.IUCN Red List: .

Nasturtium Officinale
Watercress or yellowcress (''Nasturtium officinale'') is a species of aquatic flowering plant in the cabbage family Brassicaceae. Watercress is a rapidly growing perennial plant native to Europe and Asia. It is one of the oldest known leaf vegetables consumed by humans. Watercress and many of its relatives, such as garden cress, mustard, radish, and wasabi, are noteworthy for their piquant flavors. The hollow stems of watercress float in water. The leaf structure is pinnately compound. Small, white, and green inflorescences are produced in clusters and are frequently visited by insects, especially hoverflies, such as ''Eristalis'' flies. Taxonomy Watercress is listed in some sources as belonging to the genus ''Rorippa'', although molecular evidence shows those aquatic species with hollow stems are more closely related to ''Cardamine'' than ''Rorippa''. Despite the Latin name, watercress is not particularly closely related to the flowers popularly known as nasturtiums (''Trop ...

Berula Erecta
''Berula erecta'', known as lesser water-parsnip or cutleaf waterparsnip or narrow-leaved water-parsnip, is a member of the carrot family. Growing to around tall, it is found in or by water. It is widespread across much of Europe, Asia, Australia, and North America. ''Berula erecta'' has a hollow stem. Underwater leaves consist of compound with thread-like lobes; leaves above the surface of the water are flatter and broader. The plant produces many small white flowers in a compound umbel. Description ''Berula erecta'' occurs on poorly drained neutral and acidic soils of the lowlands and upland fringe. It is found in the South West of England, especially in Devon. It typically resides in shallow aquatic environments containing moderate nutrient levels. During the winter, its stem and body become completely submerged underwater. ''Berula erecta'' has been shown to survive and grow better after living in stressful conditions with either limiting or excess nutrients or mechanica ...

× Beruladium Procurrens
× ''Beruladium procurrens'' is an intergeneric hybrid plant in the umbellifer family (Apiaceae); the result of hybridisation between ''Berula erecta'' (lesser water parsnip) and ''Helosciadium nodiflorum'' (fool's water cress). Discovery In July 1979 Max Walters collected an unidentified plant from Chippenham Fen, Cambridgeshire, England; it resembled ''H. nodiflorum'', but grew as a floating mass in a fen ditch with small, pedunculate umbels rising above the water surface. Later that year, the specimen was exhibited as a living plant at the annual BSBI exhibition meeting at the British Museum in London. An initial putative determination of ''H. repens'' was made, but as the plants were found to produce poor pollen and did not develop ripe fruits a hybrid origin was deemed more likely, possibly ''H. repens'' x ''H. nodiflorum''. Later suggestions included a depauperate example of ''B. erecta'', which can be confused with ''H. nodiflorum'' in the vegetative state, or el ...

Wilhelm Daniel Joseph Koch
Wilhelm Daniel Joseph Koch (5 March 1771 – 14 November 1849) was a German physician and botanist from Kusel, a town in the Rhineland-Palatinate. Koch studied medicine at the Universities of Jena and Marburg, and afterwards was a '' Stadtphysicus'' (state physician) in Trarbach and Kaiserslautern (1798). In 1824 he became a professor of medicine and botany at the University of Erlangen, where he stayed for the remainder of his life. At Erlangen, he was also director of the botanical gardens. In 1833, he was elected a foreign member of the Royal Swedish Academy of Sciences. Among his better written efforts was a synopsis on German and Swiss flora titled ''Synopsis florae germanicae et helveticae'' (1835–37). Another noteworthy publication of his was ''Catalogus plantarum, quae in ditione Florae Palatinatus'' (Catalog of Palatinate flora) (1814). He died in Erlangen. He has been honoured in the naming of 2 plant genera; '' Eokochia'' (from the family Amaranthaceae), and ''Kochi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
