Thistle Creek (Utah)
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 planton 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 flower heads. The comparative amount of spininess varies dramatically by species. For example, '' Cirsium heterophyllum'' has minimal spininess while ''Cirsium spinosissimum'' is the opposite. Typically, species adapted to dry environments have greater spininess. The term thistle is sometimes taken to mean precisely those plants in the tribe Cardueae (synonym: Cynareae), especially the genera '' Carduus'', ''Cirsium'', and ''Onopordum''. However, plants outside this tribe are sometimes called thistles. Biennial thistles are particularly noteworthy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teasel
''Dipsacus'' is a genus of flowering plant in the family Caprifoliaceae. The members of this genus are known as teasel, teazel or teazle. The genus includes about 15 species of tall herbaceous biennial plants (rarely short-lived perennial plants) growing to tall. ''Dipsacus'' species are native to Europe, Asia and northern Africa. Etymology The genus name (''Dipsacus'') is derived from the Greek word for thirst (''dipsa'') and refers to the cup-like formation made where sessile leaves merge at the stem. The name ''teasel'' derives from words such as Old English ''tǣsl'', ''tǣsel''; relating to the verb "to tease" – the dried heads of the plant were once used in the textile industry to raise the nap on woolen cloth. Description Teasels are easily identified with their prickly stem and leaves, and the inflorescence of purple, dark pink, lavender or white flowers that form a head on the end of the stem(s). The inflorescence is ovoid, long and broad, with a basal whorl of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floral Emblem
In a number of countries, plants have been chosen as symbols to represent specific geographic areas. Some countries have a country-wide floral emblem; others in addition have symbols representing subdivisions. Different processes have been used to adopt these symbols – some are conferred by government bodies, whereas others are the result of informal public polls. The term floral emblem, which refers to flowers specifically, is primarily used in Australia and Canada. In the United States, the term state flower is more often used. National plants Africa Mauritius The national flower of Mauritius is '' Trochetia boutoniana''. Seychelles The national flower of the Seychelles is the tropicbird orchid (known locally as ''orkid payanke''), '' Angraecum eburneum''. South Africa The national flower of South Africa is the King Protea, ''Protea cynaroides''. Tunisia The national flower of Tunisia is jasmine. It was chosen as a symbol for the 2010 Tunisian Revolution. Asia Ban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cnicus
''Cnicus benedictus'', known by the common names St. Benedict's thistle, blessed thistle, holy thistle and spotted thistle, 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''. The related genus ''Notobasis'' is included in ''Cnicus'' by some botanists; it differs in slender, much spinier leaves, and purple flowers. Growth It is an annual plant growing to 60 cm tall, with leathery, hairy leaves up to 30 cm long and 8 cm broad, with small spines on the margins. The flowers are yellow, produced in a dense flowerhead (capitulum) 3–4 cm diameter, surrounded by numer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Centaurea
''Centaurea'' () is a genus of over 700 species of herbaceous thistle-like flowering plants in the family Asteraceae. Members of the genus are found only north of the equator, mostly in the Eastern Hemisphere; the Middle East and surrounding regions are particularly species-rich. In the western United States, yellow starthistles are an invasive species. Around the year 1850, seeds from the plant had arrived to the state of California. It is believed that those seeds came from South America. Common names Common names for this genus are centaury, centory, starthistles, knapweeds, centaureas and the more ambiguous "bluets"; a vernacular name used for these plants in parts of England is "loggerheads" ( common knapweed). The ''Plectocephalus'' group – possibly a distinct genus – is known as basketflowers. "Cornflower" is used for a few species, but that term more often specifically means either '' C. cyanus'' (the annual cornflower) or '' Centaurea montana'' (the perennial ...

Carthamus
The genus ''Carthamus'', the distaff thistles, includes plants in the family Asteraceae. The group is native to Europe, North Africa, and parts of Asia. The flower has been used since ancient times in the Philippines, which it has been called ''kasubha'' by the Tagalog people. The best known species is the safflower ''(Carthamus tinctorius Safflower (''Carthamus tinctorius'') is a highly branched, herbaceous, thistle-like annual plant in the family Asteraceae.

Bristle Thistle
A bristle is a stiff hair or feather (natural or artificial), either on an animal, such as a pig, a plant, or on a tool such as a brush or broom. Synthetic types Synthetic materials such as nylon are also used to make bristles in items such as brooms and sweepers. Bristles are often used to make brushes for cleaning purposes, as they are strongly abrasive; common examples include the toothbrush and toilet brush. The bristle brush and the scrub brush are common household cleaning tools, often used to remove dirt or grease from pots and pans. Bristles are also used on brushes other than for cleaning, notably paintbrushes. Bristles are distinguished as '' flagged'' (split, bushy ends) or ''unflagged;'' these are also known as ''flocked'' or ''unflocked'' bristles. In cleaning applications, flagged bristles are suited for dry cleaning (due to picking up dust better than unflagged), and unflagged suited for wet cleaning (due to flagged ends becoming dirty and matted when wet).

Musk Thistle - Geograph
Musk (Persian: مشک, ''Mushk'') is a class of aromatic substances commonly used as base notes in perfumery. They include glandular secretions from animals such as the musk deer, numerous plants emitting similar fragrances, and artificial substances with similar odors. ''Musk'' was a name originally given to a substance with a strong odor obtained from a gland of the musk deer. The substance has been used as a popular perfume fixative since ancient times and is one of the most expensive animal products in the world. The name originates from the Late Greek μόσχος 'moskhos', from Persian 'mushk', similar to Sanskrit मुष्क muṣka ("testicle"), derived from Proto-Indo-European noun ''múh₂s'' meaning "mouse". The deer gland was thought to resemble a scrotum. It is applied to various plants and animals of similar smell (e.g. muskox) and has come to encompass a wide variety of aromatic substances with similar odors, despite their often differing chemical structu ...
