Oenanthe (plant)
''Oenanthe'', known as water dropworts, oenanthes, water parsleys, and water celeries, are a genus of plants in the family Apiaceae. Most of the species grow in damp ground, such as in marshes or in water. Several of the species are extremely poisonous, the active poison being oenanthotoxin. The most notable of these is ''O. crocata'', which lives in damp, marshy ground, and resembles celery with roots like a bunch of large white carrots. The leaves may be eaten safely by livestock, but the stems, and especially the carbohydrate-rich roots are much more poisonous. Animals familiar with eating the leaves may eat the roots when these are exposed during ditch clearance: one root is sufficient to kill a cow, and human fatalities are also known. It has been referred to as the most poisonous of all British plants, and is considered particularly dangerous because of its similarity to several edible plants. The species '' O. javanica'', commonly known as Chinese celery or Japanese pars ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oenanthe Aquatica
''Oenanthe aquatica'', fine-leaved water-dropwort, is an aquatic flowering plant in the carrot family. It is widely distributed from the Atlantic coast of Europe to central Asia. Description Fine-leaved water-dropwort is a hairless, annual to perennial herb about 150 cm tall. Young plants have tubers, which disappear by mid-summer. The stem is hollow and striated, normally about 1 cm in diameter but exceptionally reaching 8 cm, erect or sprawling, rooting at the nodes of any submerged sections. Very large sprawling plants have been found to have stems up to 2 m long. The upper (aerial) leaves are 2- to 3-pinnate, finely divided into lanceolate (sword-shaped) to ovate leaflets up to 5 mm long; the lower leaves are 3–4 pinnate, with very narrow (thread-like) leaflets under water, but flat, ovate leaf segments if emergent. The leaf stalks form a sheath around the stem at the base. It flowers between June and September in northern Europe, the inflorescence arisin ...

Oenanthe Crocata
''Oenanthe crocata'', hemlock water-dropwort (sometimes known as dead man's fingers) is a flowering plant in the carrot family, native to Europe, North Africa and western Asia. It grows in damp grassland and wet woodland, often along river and stream banks. All parts of the plant are extremely toxic and it has been known to cause human and livestock poisoning. Description Hemlock water-dropwort is a robust hairless perennial growing up to 150 cm tall with hollow, cylindrical, grooved stems up to 3.5 cm across. The stems are often branched. The upper part of the roots include five or more obovoid, pale yellow, fleshy tubers up to 6 cm long, which exude a yellowish oily fluid when cut that stains the skin. The lower leaves are 3–4 times pinnate, triangular, with oval toothed leaflets 10–20 mm long, that are basally tapered to the stalk ( cuneate). The upper leaves are 1–2 pinnate, with narrower lobes and a shorter petiole (leaf stalk). All the leaves ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oenanthe Fluviatilis
''Oenanthe fluviatilis'', the river water-dropwort, is a flowering plant in the carrot family, Apiaceae, which is endemic to north-west Europe. It grows only in clear, unpolluted rivers and is declining throughout its range. Description River water-dropwort is a hairless perennial with hollow, ridged stems up to 1 m long, submerged or floating in rivers, or emergent in marginal swamps and during periods of low flow in summer. The stems creep along the surface of mud, or on the bottom of a river, rooting at the nodes. These extend upwards through the water column, becoming thicker as they ascend, to a diameter of about an inch (2.5 cm), with a central hollow about half that size. Young plants have tubers, which disappear as they mature, leaving just fibrous roots. The lower, underwater leaves are once to twice pinnate, with distinctive cuneate (diamond shaped) segments which are deeply divided into almost linear lobes (especially so in faster-flowing water), with ...

Oenanthe Fistulosa
''Oenanthe fistulosa'', tubular water-dropwort, is a flowering plant in the carrot family, native to Europe, North Africa and western parts of Asia. It is an uncommon plant of wetlands, growing around pools and along ditches, mainly in areas of high conservation value. Description Tubular water-dropwort is a hairless, stoloniferous perennial growing up to 80 cm tall with brittle, hollow, inflated cylindrical stems 0.5 cm in diameter, which are constricted at the nodes (hence the specific name ''fistulosa''). Unlike some other water-dropworts, it has no swollen tubers among the roots, but it can reproduce vegetatively by the lengthy stolons. The leaves vary widely in shape, with the upper ones being typically pinnate and having narrow, almost linear segments, while the lower ones can be 2- or even 3-times pinnate, with broader, flat leaflets, more like those of other umbellifers. The leaf stalks of the upper leaves are fistular, like the stem, and longer than the pin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
