Hieracium Attenboroughianum
''Hieracium attenboroughianum'', or Attenborough's hawkweed, is a species of hawkweed in the genus ''Hieracium'', found only in the Brecon Beacons in south Wales. It was named after the naturalist Sir David Attenborough by taxonomist Tim Rich, who said: Rich was one of the team that first discovered the species, in 2004. The species is classified is a member of the '' H. britannicum'' group in ''Hieracium'' section Stelligera Zahn. It is related to '' H. britannicoides'' (P. D. Sell), but differs in having in cupped, dark green leaves and sparse, medium simple eglandular hairs and many glandular hairs on the involucral bracts. Only around 300 plants occur on Old Red Sandstone mountain ledges on Cribyn.

List Of Things Named After David Attenborough And His Works
This is a list of things named after English broadcaster, biologist, natural historian and author Sir David Attenborough, and his audiovisual works. Buildings * David Attenborough Building in Cambridge, which houses the Cambridge University Museum of Zoology and the Cambridge Conservation Initiative (CCI). Ships * RRS ''Sir David Attenborough'', a British polar research ship; famously involved in the ''Boaty McBoatface'' naming poll controversy. Taxonomy David Attenborough's long trajectory working on nature documentaries and supporting conservation initiatives has made him an inspiration and a popular choice among naturalists to honour him with eponyms when naming newly described organisms. Attenborough himself has said that this is the "biggest of compliments that you could ask from any scientific community." As of 2022, there are more than 50 taxa (genera and species) of organisms that have been named after David Attenborough. Additionally, there is at least one species ...

David Attenborough
Sir David Frederick Attenborough (; born 8 May 1926) is an English broadcaster, biologist, natural historian and author. He is best known for writing and presenting, in conjunction with the BBC Natural History Unit, the nine natural history documentary series forming the ''Life'' collection, a comprehensive survey of animal and plant life on Earth. Attenborough was a senior manager at the BBC, having served as controller of BBC Two and director of programming for BBC Television in the 1960s and 1970s. First becoming prominent as host of ''Zoo Quest'' in 1954, his filmography as writer, presenter and narrator has spanned eight decades; it includes ''Natural World'', ''Wildlife on One'', the ''Planet Earth'' franchise, ''The Blue Planet'' and its sequel. He is the only person to have won BAFTA Awards in black and white, colour, high-definition, 3D and 4K resolutions. Over his life he has collected dozens of honorary degrees and awards, including 3 Emmy Awards for ...

Hawkweed
''Hieracium'' (), known by the common name hawkweed and classically as (from ancient Greek ιεράξ, 'hawk'), is a genus of flowering plant in the family Asteraceae, and closely related to dandelion (''Taraxacum''), chicory ('' Cichorium''), prickly lettuce (''Lactuca'') and sow thistle (''Sonchus''), which are part of the tribe Cichorieae. Hawkweeds, with their 10,000+ recorded species and subspecies, do their part to make Asteraceae the second largest family of flowering plants. Some botanists group all these species or subspecies into approximately 800 accepted species, while others prefer to accept several thousand species. Since most hawkweeds reproduce exclusively asexually by means of seeds that are genetically identical to their mother plant (apomixis or agamospermy), clones or populations that consist of genetically identical plants are formed and some botanists (especially in UK, Scandinavia and Russia) prefer to accept these clones as good species (arguing t ...

Brecon Beacons
The Brecon Beacons ( cy, Bannau Brycheiniog, ) are a mountain range in South Wales. In a narrow sense, the name refers to the range of Old Red Sandstone peaks which lie to the south of Brecon. Sometimes referred to as "the central Beacons" they include South Wales' highest mountain, Pen y Fan. The range forms the central section of the Brecon Beacons National Park (), a designation which also encompasses ranges both to the east and the west of "the central Beacons". This much wider area is also commonly referred to as "the Brecon Beacons", and it includes the Black Mountains to the east as well as the similarly named but quite distinct Black Mountain to the west. The highest peaks include Fan Brycheiniog to the west and Pen y Fan in the central part. They share the same basic geology as the central range, and so exhibit many similar features, such as the north-facing escarpment and glacial features such as lakes and cwms ( cirques). Geography The Brecon Beacons range, in ...

Wales
Wales ( cy, Cymru ) is a Countries of the United Kingdom, country that is part of the United Kingdom. It is bordered by England to the Wales–England border, east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 and has a total area of . Wales has over of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon (), its highest summit. The country lies within the Temperateness, north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a Kingdom of Wales, kingdom under Gruffydd ap Llywelyn in 1055. Wales is regarded as one of the Celtic nations. The Conquest of Wales by Edward I, conquest of Wales by Edward I of England was completed by 1283, th ...

Glandular Hair
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants and ...

Involucral Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and pa ...

Old Red Sandstone
The Old Red Sandstone is an assemblage of rocks in the North Atlantic region largely of Devonian age. It extends in the east across Great Britain, Ireland and Norway, and in the west along the northeastern seaboard of North America. It also extends northwards into Greenland and Svalbard. These areas were a part of the ancient continent of Euramerica, Euramerica/Laurussia. In Britain it is a lithostratigraphy, lithostratigraphic unit (a sequence of rock strata) to which Stratigraphy, stratigraphers accord Geological unit#Lithostratigraphic units, supergroup status and which is of considerable importance to early paleontology. For convenience the short version of the term, ORS is often used in literature on the subject. The term was coined to distinguish the sequence from the younger New Red Sandstone which also occurs widely throughout Britain. Sedimentology The Old Red Sandstone describes a suite of sedimentary rocks deposited in a variety of environments during the Devonian ...
