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 c ...

Houstonia (plant)
''Houstonia'' (bluet) is a genus of plants in the family Rubiaceae. Many species were formerly classified, along with other genera since segregated elsewhere, in a more inclusive genus ''Hedyotis''. Bluets are often small and delicate. For example, ''H. rosea'' may grow only one inch tall. Some species are single stemmed and others have multiple stems in bunches. Flowers are blue, purple, lavender, white, or rose, often with shades of one color present in an individual population. Flowers have 4 sepals, colloquially denominated "petals", a salverform corolla with 4 lobes, and an inferior ovary. Some species exhibit heterostyly. The fruit is an often roughly cordate capsule enclosing many seeds and which usually dehisces via a suture across its apex. ''Houstonia'' consists of 20 species native to North America. Another 5 species are classified in the genus '' Stenaria''; ''Houstonia'' without ''Stenaria'' is paraphyletic. Close relatives of the genus are '' Oldenlandia microth ...

Oldenlandiopsis
''Oldenlandiopsis'' (creeping-bluet) is a genus of flowering plants in the family Rubiaceae. It is monospecific, comprising only one species, ''Oldenlandiopsis callitrichoides''. This species had previously been placed in ''Hedyotis'' or in '' Oldenlandia''. It is native to the West Indies, southern Mexico, and Central America. It is naturalized elsewhere, including Florida, Hawaii, South America, and tropical Africa. ''Oldenlandiopsis'' was established in 1990 by Edward E. Terrell and Walter H. Lewis. The generic name indicates a likeness to ''Oldenlandia''. The specific epithet refers to a superficial resemblance to Callitriche, a genus in Plantaginaceae. ''Oldenlandiopsis callitrichoides'' was first described in 1862 by August Grisebach as ''Oldenlandia callitrichoides'' in a pre-print of a paper that was published the following year in ''Memoirs of the American Academy of Arts and Sciences''. ''Oldenlandiopsis'' is a member of the tribe Spermacoceae. Within the tribe, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enallagma
''Enallagma'' is a genus of damselflies in the family Coenagrionidae commonly known as bluets. Adults range in length from 28 mm to 40 mm. Males are usually bright blue and black while the coloration of females varies by species. Bluets can be distinguished from the similar vivid dancer by wing position; at rest, bluets' wings hang down on either side of their body, while vivid dancers hold their wings above their body. Bluets also have shorter leg spines. Subspecies The genus consists of the following species: *'' Enallagma ambiguum'' *'' Enallagma anna'' – River Bluet *'' Enallagma annexum'' – Northern Bluet *'' Enallagma antennatum'' – Rainbow Bluet *''Enallagma aspersum'' – Azure Bluet *'' Enallagma basidens'' – Double-Striped Bluet *'' Enallagma boreale'' – Boreal Bluet *'' Enallagma cardenium'' – Purple Bluet *'' Enallagma carunculatum'' – Tule Bluet *'' Enallagma civile'' – Familiar Bluet *'' Enallagma clausum'' – Alkali Bluet *'' Enalla ...

Coenagrion
''Coenagrion'' is a genus of damselfly, damselflies in the family Coenagrionidae, commonly called the Eurasian Bluets (although three species are found in North America: ''Coenagrion angulatum'', ''Coenagrion interrogatum'', and ''Coenagrion resolutum''). Species of ''Coenagrion'' are generally medium-sized, brightly coloured damselflies. Species The genus ''Coenagrion'' includes the following species: Biology Thermal adaptation This genus's capacity for thermal plasticity, phenotypically plastic responses to the surface air temperature is important to species' ranges. These thermal responses will also decide a great deal of these species' phenotypic plasticity and climate change, responses to climate change. Nilsson-Örtman ''et al.'', 2012 find a high degree of thermal adaptation in high latitude populations of ''Coenagrion''. They found similar plasticity even for various sympatric species at the same locations, and despite the highly variable weather at such latitudes. ...

Bluets (poetry Collection)
''Bluets'' is a book by American author Maggie Nelson, published by Wave Books in 2009. The work hybridizes several prose and poetry styles as it documents Nelson's multifaceted experience with the color blue, and is often referred to as lyric essay or prose poetry. It was written between 2003 and 2006. The book is a philosophical and personal meditation on the color blue, lost love, grief and existential solitude. The book is full of references to other writers, philosophers and artists. The title refers to the painting ''Bluets'' by the artist Joan Mitchell. Structure and subject ''Bluets'' is a "formal experiment" that contains an arrangement of 240 loosely-linked prose poems which Nelson refers to as "propositions". Each proposition is either a sentence or a short paragraph, none longer than two hundred words; the book totals some nineteen thousand words. The propositions are arranged neither chronologically nor thematically, but in each one, Nelson produces links between di ...
