Urtica Dioica
''Urtica dioica'', often known as common nettle, burn nettle, stinging nettle (although not all plants of this species sting) or nettle leaf, or just a nettle or stinger, is a herbaceous perennial flowering plant in the family Urticaceae. Originally native to Europe, much of temperate Asia and western North Africa, it is now found worldwide, including New Zealand and North America. The species is divided into six subspecies, five of which have many hollow stinging hairs called trichomes on the leaves and stems, which act like hypodermic needles, injecting histamine and other chemicals that produce a stinging sensation upon contact ("contact urticaria", a form of contact dermatitis). The plant has a long history of use as a source for traditional medicine, food, tea, and textile raw material in ancient (such as Saxon) and modern societies. Description ''Urtica dioica'' is a dioecious, herbaceous, perennial plant, tall in the summer and dying down to the ground in winter. ...

Urtica
''Urtica'' is a genus of flowering plants in the family Urticaceae. Many species have stinging hairs and may be called nettles or stinging nettles, although the latter name applies particularly to ''Urtica dioica''. ''Urtica'' species are food for the caterpillars of numerous Lepidoptera (butterflies and moths), such as the tortrix moth ''Syricoris lacunana'' and several Nymphalidae, such as ''Vanessa atalanta'', one of the red admiral butterflies. The generic name ''Urtica'' derives from the Latin for sting. Description ''Urtica'' species grow as annuals or perennial herbaceous plants, rarely shrubs. They can reach, depending on the type, location and nutrient status, a height of . The perennial species have underground rhizomes. The green parts have stinging hairs. Their often quadrangular stems are unbranched or branched, erect, ascending or spreading. Most leaves and stalks are arranged across opposite sides of the stem. The leaf blades are elliptic, lanceolate, ovate or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solanum Carolinense
''Solanum carolinense'', the Carolina horsenettle, is not a true nettle, but a member of the Solanaceae, or nightshade family. It is a perennial herbaceous plant, native to the southeastern United States, though its range has expanded throughout much of temperate North America. The plant is an invasive in parts of Europe, Asia, and Australia. The stem and undersides of larger leaf veins are covered with prickles. "Horsenettle" is also written "horse nettle" or "horse-nettle", though USDA publications usually use the one-word form. Though there are other horsenettle nightshades, ''S. carolinense'' is the species most commonly called ''"the'' horsenettle". Other common names include radical weed, sand brier or briar, bull nettle, tread-softly, Solanum mammosum ("apple of Sodom"), devil's tomato and wild tomato. Description Leaves are alternate, elliptic-oblong to oval, long, and each is irregularly lobed or coarsely toothed. Both surfaces are covered with fine hairs. Leav ...

Urtica Ferox
''Urtica ferox'', commonly known as tree nettle and in Māori: ongaonga, taraonga, taraongaonga, оr okaoka, is a species of nettle endemic to New Zealand. Unlike the other species in the genus ''Urtica'' found in New Zealand, all of which are herbaceous, ongaonga is a large woody shrub that can grow to a height of , with the base of the stem reaching in thickness. It has large spines that can result in a painful sting that lasts several days. Ongaonga is the main source of food for larvae of the New Zealand red admiral butterfly or kahukura, ''Vanessa gonerilla''. Description ''U. ferox'' can grow to a height of 3 m (9.8 ft) with the base of the stem reaching 12 cm (4.7 in) in thickness.

Celtis
''Celtis'' is a genus of about 60–70 species of deciduous trees, commonly known as hackberries or nettle trees, widespread in warm temperate regions of the Northern Hemisphere. The genus is part of the extended hemp family (Cannabaceae). Description ''Celtis'' species are generally medium-sized trees, reaching tall, rarely up to tall. The leaves are alternate, simple, long, ovate-acuminate, and evenly serrated margins. Diagnostically, ''Celtis'' can be very similar to trees in the Rosaceae and other rose motif families. Small flowers of this monoecious plant appear in early spring while the leaves are still developing. Male flowers are longer and fuzzy. Female flowers are greenish and more rounded. The fruit is a small drupe in diameter, edible in many species, with a dryish but sweet, sugary consistency, reminiscent of a date.

Stinging Plant
A stinging plant or a plant with stinging hairs is a plant with hairs (trichomes) on its leaves or stems that are capable of injecting substances that cause pain or irritation. Other plants, such as opuntias, have hairs or spines that cause mechanical irritation, but do not inject chemicals. Stinging hairs occur particularly in the families Urticaceae, Loasaceae, Boraginaceae (subfamily Hydrophylloideae) and Euphorbiaceae. Such hairs have been shown to deter grazing mammals, but are no more effective against insect attack than non-stinging hairs. Many plants with stinging hairs have the word "nettle" in their English name, but may not be related to "true nettles" (the genus ''Urtica''). Though several unrelated families of plants have stinging hairs, their structure is generally similar. A solid base supports a single elongated cell with a brittle tip. When the tip is broken, the exposed sharp point penetrates the skin and pressure injects toxins. The precise chemicals involved ...

Lamium Album
''Lamium album'', commonly called white nettle or white dead-nettle, is a flowering plant in the family Lamiaceae. It is native throughout Europe and Asia, growing in a variety of habitats from open grassland to woodland, generally on moist, fertile soils. Description ''L. album'' is an herbaceous perennial plant growing to tall, with green, four-angled stems. The leaves are long and broad, triangular with a rounded base, softly hairy, and with a serrated margin and a petiole up to long; like many other members of the Lamiaceae, they appear superficially similar to those of the stinging nettle (''Urtica dioica'') but do not sting, hence the common name "dead-nettle". The flowers are white, produced in whorls ('verticillasters') on the upper part of the stem, the individual flowers long. The flowers are visited by many types of insects, but mostly by long-tongued insects, like bees. Distribution ''L. album'' is native to Eurasia, from Ireland in the West to Japan in the Ea ...

Cnidoscolus Stimulosus
''Cnidoscolus stimulosus'', the bull nettle, spurge nettle, tread-softly or finger rot, is a perennial herb covered with stinging hairs, native to southeastern North America. A member of the family Euphorbiaceae (spurge family), it is not a true nettle. It prefers sandy, well-drained soil and mostly exists in pine/blackjack oak forests on sandhills, rims of Carolina bays, dunes, dry pastures, fields and roadsides. Description The green leaves of this plant are alternate, consisting of three to five untoothed lobes. The large, white flowers have five petals. Male and female flowers are on different plants. Flowers occur throughout the spring and summer followed by a small capsule that produces three large seeds. The entire plant above ground, including the flower petals, is covered with stinging hairs. The tap root can be used as an excellent potato substitute, tasting like pasta. As the common names imply, the urticating hairs on this plant contain a caustic irritant that infli ...

Boehmeria
''Boehmeria'' is a genus of 47 species of flowering plants in the nettle family Urticaceae. Of the species, 33 are indigenous to the Old World and 14 to the New World; no species is indigenous to both the Old and New Worlds. The species include herbaceous perennials, shrubs and small trees. Although related to the similar-looking species of the stinging nettles of genus ''Urtica'', species of ''Boehmeria'' do not have stinging hairs. Because of the similarity in appearance, some species are commonly called "false nettles". This genus is named in honor of the German botanist, Georg Rudolf Boehmer. Fossil record 14 fossil fruits of †''Boehmeria sibirica'' have been extracted from borehole samples of the Middle Miocene fresh water deposits in Nowy Sacz Basin, West Carpathians, Poland. Cultivation and uses One species, ramie (''Boehmeria nivea'') is an important fibre crop. Some are also used as ornamental plants. ''Boehmeria'' species are used as food plants by the larvae of s ...
