verbascum thapsus history

[74] Leaves were smoked to attempt to treat lung ailments, a tradition that in America was rapidly transmitted to Native American peoples. With noun/verb tables for the different cases and tenses links to audio pronunciation and … [79] It was also part of the National Formulary in the United States[75] and United Kingdom. giganteum and subsp. option. [17][20] Introduced American populations show much less variation. In such ecological contexts, it crowds out native herbs and grasses; its tendency to appear after forest fires also disturbs the normal ecological succession. Specific epithet honors the ancient village of Thapsus (now in ruins) located near Carthage in modern day Tunisia. Access supplemental materials and multimedia. The second-year plants normally produce a single unbranched stem, usually 1–2 m tall. [3][4] The leaves are large, up to 50 cm long. History has shown that Verbascum thapsus provides cough relief related to various . The flowering period of V. thapsus lasts from June to August in most of its range, extending to September or October in warmer climates. The History of the British Flora, A Factual Basis for Phytogeography by, "Element Stewardship Abstract for Verbascum thapsus", "Verbascum oreophilum var. ii. [9] Useful insects are also hosted by great mullein, including predatory mites of the genera Galendromus, Typhlodromus and Amblyseius, the minute pirate bug Orius tristicolor[67] and the mullein plant bug (Campylomma verbasci). [9], Flowers are pentamerous with (usually) five stamen, a five-lobed calyx tube and a five-petalled corolla, the latter bright yellow and an 1.5–3 cm (0.59–1.18 in) wide. 3. 105 viride, ii. [66], Despite not being an agricultural weed in itself, it hosts a number of insects and diseases, including both pests and beneficial insects. [19] Great mullein rarely establishes on new grounds without human intervention because its seeds do not disperse very far. While it can also grow in areas where some vegetation already exists, growth of the rosettes on bare soil is four to seven times more rapid. [12] Its population pattern typically consists of an ephemeral adult population followed by a long period of dormancy as seeds.

[19], The taxonomy of Verbascum has not undergone any significant revision since Svanve Mürbeck's monographies in the 1930s, with the exception of the work of Arthur Huber-Morath, who used informal group in organizing the genus for the florae of Iran and Turkey to account for many intermediate species. The journal Burning is ineffective, as it only creates new bare areas for seedlings to occupy. This work describes life history variation in Verbascum thapsus L. with latitude. Authorized users may be able to access the full text articles at this site. European reference books call it "great mullein". Garrett, Kimball L., Raphael, Martin G. and Dixon, Rita D. (1996). In this study, we investigated the antispasmodic and anthelmintic activities of crude aqueous methanolic extract of the plant. [7], On flowering plants, the leaves are alternately arranged up the stem. In more northerly climates, biennial and triennial plants are favoured because they can produce more seed in the short but predictable growing season. [9][82], Due to its weedy capacities, the plant, unlike other species of the genus (such as V. phoeniceum), is not often cultivated. Question Author. It grows in a wide variety of habitats, but prefers well-lit, disturbed soils, where it can appear soon after the ground receives light, from long-lived seeds that persist in the soil seed bank. [12] Ground herbicides, like tebuthiuron, are also effective, but recreate bare ground and require repeated application to prevent regrowth. Journal of Ecology. [56] Because of this, and because the plant is an extremely prolific seed bearer (each plant produces hundreds of capsules, each containing up to 700+ seeds,[19] with a total up to 180,000[9][10] or 240,000[12] seeds), it remains in the soil seed bank for extended periods of time, and can sprout from apparently bare ground,[10] or shortly after forest fires long after previous plants have died. ©2000-2020 ITHAKA. of case studies. Verbascum subsect.

Although this plant is a recent arrival to North America, Native Americans used the ground seeds of this plant as a paralytic fish poison due to their high levels of rotenone. Although individuals are easy to remove by hand, populations are difficult to eliminate permanently. They are also used as emollient applications to hard tumours and in pulmonary complaints in cattle hence one of its popular names is Bullock’s Lung-wort. search Search the Wayback Machine. [3] The flowering stem is solid and 2–2.5 cm (nearly an inch) across, and occasionally branched just below the inflorescence,[4] usually following damage. [27] In subsp. They include mullein thrips (Haplothrips verbasci),[67] Gymnaetron tetrum (whose larva consume the seeds) and the mullein moth (Cucullia verbasci). For example, in the “biennial” Verbascum thapsus, reproduction may actually take place in the first, second, or third year of growth depending on latitude and successional status of the habitat (Reinartz, 1984a, b). The effects of former human occupation or. Reinartz, James A. [57] The seeds are generally too small for birds to feed on,[11] although the American goldfinch has been reported to consume them. Populations were chosen at the northern (southern Canada) and southern (southern Texas and Georgia) limits of its range in North America, and in North Carolina and came from a range of the habitats occupied by the species. [11], For the purpose of botanical nomenclature, Verbascum thapsus was first described by Carl Linnaeus in his 1753 Species Plantarum. After flowering the entire plant usually dies at the end of its second year,[10] but some individuals, especially in the northern parts of the range, require a longer growth period and flower in their third year. [67] It is also a potential reservoir of the cucumber mosaic virus, Erysiphum cichoraceum (the cucurbit powdery mildew) and Texas root rot. 2.

Journal of Ecology An infusion of the root is also used to treat athlete's foot. Papers [44][45][46][47] It has also been reported in Japan. These make the plant a potential reservoir for overwintering pests. It is a hairy biennial plant that can grow to 2 m tall or more. Read Online (Free) relies on page scans, which are not currently available to screen readers. [69394] Its small, yellow flowers are densely grouped on a tall stem, which grows from a large rosette of leaves. respiratory illnesses, including asthma and tuberculosis. [5][43][44] In northern Europe, it grows from sea level up to 1,850 m altitude,[4] while in China it grows at 1,400–3,200 m altitude. Eaton went so far as to write: "When botanists are so infatuated with wild speculation, as to tell us the mullein was introduced, they give our youngest pupils occasion to sneer at their teachers. (7) In the common garden, plants from southern populations began to bolt and flower earlier than those from the other populations. Verbascum thapsus was used medicinally by some Native American tribes. [42], Verbascum thapsus has a wide native range including Europe, northern Africa and Asia, from the Azores and Canary Islands east to western China, north to the British Isles, Scandinavia and Siberia, and south to the Himalayas. [5][6] This cover is particularly thick on the leaves, giving them a silvery appearance. 177 1753. oreophilum and Verbascum cheiranthifolium var. [80] Native Americans and American colonists lined their shoes with leaves from the plant to keep out the cold. The electronic version of Journal of Ecology nigrum). Biomass partitioning, life history, and population dynamics of common mullein (Verbascum thapsus L.). [13] Flowering lasts up to three months from early to late summer (June to August in northern Europe),[4] with flowering starting at the bottom of the spike and progressing irregularly upward; each flower opens for part of a day and only a few open at the same time around the stem. They are thick and decurrent, with much variation in leaf shape between the upper and lower leaves on the stem, ranging from oblong to oblanceolate, and reaching sizes up to 50 cm long and 14 cm across (19 inches long and 5 inches wide). [31] Topical application of various V. thapsus-based preparations was recommended for the treatment of warts,[77] boils, carbuncles, hemorrhoids, and chilblains, amongst others. Of these, the most common is V. × semialbum Chaub. (1) Twenty-four natural populations of the monocarpic perennial Verbascum thapsus were mapped and studied over 3 years. There is substantial intraspecific variation in time of reproduction in most monocarpic plants. [62], Seed of Verbascum thapsus has been recorded from part of the Cromer Forest Bed series and at West Wittering in Sussex from some parts of the Ipswichian interglacial layers. [2] The plant's leaves, in addition to the seeds, have been reported to contain rotenone, although quantities are unknown. need to convey strong and ecological messages that advance our understanding [31][75] Glycyrrhizin compounds with bactericide effects in vitro were isolated from flowers.
