Vinca
''Vinca'' (; Latin: ''vincire'' "to bind, fetter") is an Old World genus of flowering plants in the family Apocynaceae, The English name periwinkle is shared with the related genus '' Catharanthus'' (and with the mollusc '' Littorina littorea''). Some ''Vinca'' species are cultivated but have also spread invasively. Additionally, some species have medicinal uses. The most widespread species is Vinca minor. Description ''Vinca'' plants are subshrubs or herbaceous, and have slender trailing stems long but not growing more than above ground; the stems frequently take root where they touch the ground, enabling the plant to spread widely. The leaves are opposite, simple broad lanceolate to ovate, long and broad; they are evergreen in four species, but deciduous in the herbaceous ''V.'' ''herbacea'', which dies back to the root system in winter.Blamey, M., & Grey-Wilson, C. (1989). ''Flora of Britain and Northern Europe''. Hodder & Stoughton.Huxley, A., ed. (1992). ''New R ...

Vinca Minor
''Vinca minor'' (common names lesser periwinkle or dwarf periwinkle) is a species of flowering plant in the dogbane family, native to central and southern Europe. Other vernacular names used in cultivation include small periwinkle, common periwinkle, and sometimes in the United States, myrtle or creeping myrtle. Description ''Vinca minor'' is a trailing subshrub, spreading along the ground and rooting along the stems to form large clonal colonies and occasionally scrambling up to high but never twining or climbing. The leaves are evergreen, opposite, long and broad, glossy dark green with a leathery texture and an entire margin. The flowers are solitary in the leaf axils and are produced mainly from early spring to mid summer but with a few flowers still produced into the autumn; they are violet-purple (pale purple or white in some cultivated selections), diameter, with a five-lobed corolla. The fruit is a pair of follicles long, containing numerous seeds. Chemistry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The flowers are hermaphrodite, axillary and solitary, violet-purple, 3–5 cm in diameter, with a five-lobed corolla. The calyx surrounding the base of the flower is long with hairy margins.

Vinca Herbacea
''Vinca herbacea'', with common name herbaceous periwinkle, is a flowering plant native to eastern Europe. Description ''Vinca herbacea'' is a herbaceous perennial growing as a trailing vine, spreading along the ground and rooting along the stems to form clonal colonies, growing up to high. The leaves are opposite, lanceolate, long and broad, glossy green with an entire margin, and nearly sessile with only a very short petiole. The flowers are produced in late summer, blue-violet or occasionally white, diameter, with a five-lobed corolla. Distribution and habitat The plant is native to eastern and southeastern Europe, from Austria south to Greece, and east to the Crimea, and also in northern Western Asia, in the Caucasus and Alborz mountains, mainly in steppe habitats. Cultivation ''Vinca herbacea'' is occasionally grown as an ornamental plant in temperate climate gardens, as a rock garden A rock garden, also known as a rockery and formerly as a rockwork, is a ga ...

Apocynaceae
Apocynaceae (, from '' Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Notable members of the family include oleander, dogbanes, milkweeds, and periwinkles. The family is native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members as well. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here. Many species are tall trees found in tropical forests, but some grow in tropical dry ( xeric) environments. Also perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter oft ...

Catharanthus
''Catharanthus'' is a genus of flowering plants in the family Apocynaceae. Like the genus ''Vinca'', they are known commonly as periwinkles. It is a perennial herb and a subshrub endemic to Madagascar, with the exception of the Catharanthus pusillius species, which is found in India and Sri Lanka. The most widely known species is Catharanthus roseus due to its renowned usage in traditional and modern medicine, specifically, as a source of cancer-treating alkaloid chemicals. Morphology The plants of Catharanthus are perennial herbs that are subshrubby, often with prostrate or erect stems that branch from the base of the plant. The genus was first described in 1837 by George Don. He characterized the plants by the morphological features of simple, opposite, or almost oppositely arranged leaves. The flowers are usually solitary in the leaf axils. Each has a calyx with five long, narrow lobes and a corolla with a tubular throat and five lobes that can be twisted. Fruits are ...

Invasive Species
An invasive species is an introduced species that harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food web. Since the 20th century, invasive species have become serious economic, social, and environmental threats worldwide. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of invasion. For millennia, humans have served as both accidental and deliberate dispersal agents, beginning with their earliest migrations, accelerating in the Age of Discovery, and accelerating again with the spread of international trade. Notable invasive plant species include the kudzu vine, giant hogweed (''Heracleum mantegazzianum''), Japanese knotw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
