Cirsium brachycephalum is a species of flowering plant belonging to the family Asteraceae. [1]
Its native range is Eastern Central and Southeastern Europe. [1]
Cirsium is a genus of perennial and biennial flowering plants in the Asteraceae, one of several genera known commonly as thistles. They are more precisely known as plume thistles. These differ from other thistle genera in having feathered hairs to their achenes. The other genera have a pappus of simple unbranched hairs.
Cirsium vulgare, the spear thistle, bull thistle, or common thistle, is a species of the Asteraceae genus Cirsium, native throughout most of Europe, Western Asia, and northwestern Africa. It is also naturalised in North America, Africa, and Australia and is an invasive weed in some areas. It is the national flower of Scotland.
Cirsium palustre, the marsh thistle or European swamp thistle, is a herbaceous biennial flowering plant in the daisy family, Asteraceae.
Mentha aquatica is a perennial flowering plant in the mint family Lamiaceae. It grows in moist places and is native to much of Europe, northwest Africa and southwest Asia.
Lotus pedunculatus, the big trefoil, greater bird's-foot-trefoil or marsh bird's-foot trefoil, is a member of the pea family (Fabaceae).
Cirsium arvense is a perennial species of flowering plant in the family Asteraceae, native throughout Europe and western Asia, northern Africa and widely introduced elsewhere. The standard English name in its native area is creeping thistle. It is also commonly known as Canada thistle and field thistle.
Thistle is the common name of a group of flowering plants characterised by leaves with sharp prickles on the margins, mostly in the family Asteraceae. Prickles can also occur all over the plant – on the stem and on the flat parts of the leaves. These prickles are an adaptation that protects the plant from being eaten by herbivores. Typically, an involucre with a clasping shape similar to a cup or urn subtends each of a thistle's flowerheads.
Cnicus benedictus, is a thistle-like plant in the family Asteraceae, native to the Mediterranean region, from Portugal north to southern France and east to Iran. It is known in other parts of the world, including parts of North America, as an introduced species and often a noxious weed. It is the sole species in the monotypic genus Cnicus. Other species once included in the genus have largely been reclassified to Cirsium, Carduus, and Centaurea.
A noxious weed, harmful weed or injurious weed is a weed that has been designated by an agricultural or other governing authority as a plant that is injurious to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock. They may also be termed invasive plants. Most noxious weeds have been introduced into an ecosystem by ignorance, mismanagement, or accident. Some noxious weeds are native. Typically they are plants that grow aggressively, multiply quickly without natural controls, and display adverse effects through contact or ingestion. Noxious weeds are a large problem in many parts of the world, greatly affecting areas of agriculture, forest management, nature reserves, parks and other open space.
The Cynareae are a tribe of flowering plants in the daisy family (Asteraceae) and the subfamily Carduoideae. Most of them are commonly known as thistles; four of the best known genera are Carduus, Cynara, Cirsium, and Onopordum.
Cirsium eriophorum, the woolly thistle, is a herbaceous biennial species of the genus Cirsium. It is widespread across much of Europe. It is a large, biennial herb with sharp spines on the tips of the leaves, and long, woolly hairs on much of the herbage. Flower heads are large and nearly spherical, with spines on the outside and many purple disc florets but no ray florets.
Cirsium occidentale, with the common name cobweb thistle or cobwebby thistle, is a North American species of thistle in the sunflower family.
The Blue Oak Ranch Reserve, a unit of the University of California Natural Reserve System, is an ecological reserve and biological field station in Santa Clara County, California. It is located on 3,260 acres (13.2 km2) in the Diablo Range, northwest of Mount Hamilton, at 1,500 ft (460 m) elevation.
Cirsium pumilum var. hillii is a type of thistle endemic to North America. The common name for this plant is Hill's thistle.
Cirsium muticum, also known as swamp thistle, marsh thistle, dunce-nettle, or horsetops, is a North American species of plants in the sunflower family, native to central and eastern Canada and the central and eastern United States.
Cirsium eatonii, commonly known as Eaton's thistle or mountaintop thistle, is a North American species of flowering plants in the aster family.
Cirsium helenioides, called melancholy thistle, is an Asian and Arctic species of plants in the thistle tribe within the sunflower family. The species is native to Greenland, Iceland, Norway, Sweden, Finland, Russia, Xinjiang, Kazakhstan.
Abrod is a national nature reserve in the Slovak municipality of Veľké Leváre in the Malacky District. The nature reserve covers an area of 92 ha of the Borská lowland area. It has a protection level of 4 under the Slovak nature protection system. The nature reserve is part of the Site of Community Importance with the same name which measures 162 ha. Since 1988 it is also a part of the Záhorie Protected Landscape Area.
Ira Waddell Clokey (1878-1950) was an American mining engineer and botanist active in the western United States. He first studied at the University of Illinois, then moved to Harvard University, graduating with a Bachelor of Science in mining engineering in 1903. From 1904 to 1915, Clokey worked as a mining engineer in Mexico. In his spare time he collected plant specimens for his personal herbarium, which, however, was almost completely destroyed during a fire in 1912. In 1921, Clokey completed a Master of Science in plant pathology from Iowa State University.
Cirsium tuberosum is a species of flowering plant belonging to the family Asteraceae.
