Kent
Kent /ˈkɛnt/ is a county in South East England and one of the home counties. It borders Greater London to the north west, Surrey to the west and East Sussex to the south west, the county shares borders with Essex via the Dartford Crossing and the French department of Pas-de-Calais through the Channel Tunnel. France can be clearly in fine weather from Folkestone and the White Cliffs of Dover. Hills in the form of the North Downs and the Greensand Ridge span the length of the county, because of its relative abundance of fruit-growing and hop gardens, Kent is known as The Garden of England. The title was defended in 2006 when a survey of counties by the UKTV Style Gardens channel put Kent in fifth place, behind North Yorkshire, Devon. Haulage and tourism are industries, major industries in north-west Kent include aggregate building materials, printing. Coal mining has played its part in Kents industrial heritage. Large parts of Kent are within the London commuter belt and its transport connections to the capital.
Twenty-eight per cent of the county forms part of two Areas of Outstanding Natural Beauty, the North Downs and The High Weald, the area has been occupied since the Palaeolithic era, as attested by finds from the quarries at Swanscombe. The Medway megaliths were built during the Neolithic era, There is a rich sequence of Bronze Age, Iron Age, and Roman era occupation, as indicated by finds and features such as the Ringlemere gold cup and the Roman villas of the Darent valley. The modern name of Kent is derived from the Brythonic word Cantus meaning rim or border and this describes the eastern part of the current county area as a border land or coastal district. Julius Caesar had described the area as Cantium, or home of the Cantiaci in 51 BC, the extreme west of the modern county was by the time of Roman Britain occupied by Iron Age tribes, known as the Regnenses. East Kent became a kingdom of the Jutes during the 5th century and was known as Cantia from about 730, the early medieval inhabitants of the county were known as the Cantwara, or Kent people.
These people regarded the city of Canterbury as their capital, in 597, Pope Gregory I appointed the religious missionary as the first Archbishop of Canterbury. In the previous year, Augustine successfully converted the pagan King Æthelberht of Kent to Christianity, the Diocese of Canterbury became Britains first Episcopal See with first cathedral and has since remained Englands centre of Christianity. The second designated English cathedral was in Kent at Rochester Cathedral, in the 11th century, the people of Kent adopted the motto Invicta, meaning undefeated. This naming followed the invasion of Britain by William of Normandy, the Kent peoples continued resistance against the Normans led to Kents designation as a semi-autonomous county palatine in 1067. Under the nominal rule of Williams half-brother Odo of Bayeux, the county was granted powers to those granted in the areas bordering Wales

Sepal
A sepal is a part of the flower of angiosperms. Usually green, sepals typically function as protection for the flower in bud, the term sepalum was coined by Noël Martin Joseph de Necker in 1790, and derived from the Greek σκεπη, a covering. Collectively the sepals are called the calyx, the outermost whorl of parts that form a flower, the word calyx was adopted from the Latin calyx, not to be confused with calix, a cup or goblet. Calyx derived from the Greek κάλυξ, a bud, a calyx, a husk or wrapping, while derived from the Greek κυλιξ, a cup or goblet. After flowering, most plants have no use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, examples include species of Acaena, some of the Solanaceae, and the water caltrop, Trapa natans. In some species the calyx not only persists after flowering, but instead of withering and this is an effective protection against some kinds of birds and insects, for example in Hibiscus trionum and the Cape gooseberry.
Morphologically, both sepals and petals are modified leaves, the calyx and the corolla are the outer sterile whorls of the flower, which together form what is known as the perianth. The term tepal is usually applied when the parts of the perianth are difficult to distinguish, e. g. the petals and sepals share the same color, or the petals are absent and the sepals are colorful. When the undifferentiated tepals resemble petals, they are referred to as petaloid, as in petaloid monocots, since they include Liliales, an alternative name is lilioid monocots. Examples of plants in which the term tepal is appropriate include genera such as Aloe, in contrast, genera such as Rosa and Phaseolus have well-distinguished sepals and petals. The number of sepals in a flower is its merosity, flower merosity is indicative of a plants classification. The merosity of a flower is typically four or five. The merosity of a monocot or palaeodicot flower is three, or a multiple of three, the development and form of the sepals vary considerably among flowering plants.
They may be free or fused together, the sepals are much reduced, appearing somewhat awn-like, or as scales, teeth, or ridges. Most often such structures protrude until the fruit is mature and falls off, examples of flowers with much reduced perianths are found among the grasses. In some flowers, the sepals are fused towards the base, in other flowers a hypanthium includes the bases of sepals and the attachment points of the stamens

Flowering plant
The flowering plants, known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approx. 13,164 known genera and a total of c.295,383 known species, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term angiosperm comes from the Greek composite word meaning enclosed seeds, the ancestors of flowering plants diverged from gymnosperms in the Triassic Period, during the range 245 to 202 million years ago, and the first flowering plants are known from 160 mya. They diversified extensively during the Lower Cretaceous, became widespread by 120 mya, angiosperms differ from other seed plants in several ways, described in the table. These distinguishing characteristics taken together have made the angiosperms the most diverse and numerous land plants, the amount and complexity of tissue-formation in flowering plants exceeds that of gymnosperms. The vascular bundles of the stem are arranged such that the xylem and phloem form concentric rings, in the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex.
In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium, the soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Among the monocotyledons, the bundles are more numerous in the stem and are scattered through the ground tissue. They contain no cambium and once formed the stem increases in diameter only in exceptional cases, the characteristic feature of angiosperms is the flower. Flowers show remarkable variation in form and elaboration, and provide the most trustworthy external characteristics for establishing relationships among angiosperm species, the function of the flower is to ensure fertilization of the ovule and development of fruit containing seeds. The floral apparatus may arise terminally on a shoot or from the axil of a leaf, occasionally, as in violets, a flower arises singly in the axil of an ordinary foliage-leaf. There are two kinds of cells produced by flowers.
Microspores, which divide to become pollen grains, are the male cells and are borne in the stamens. The female cells called megaspores, which divide to become the egg cell, are contained in the ovule. The flower may consist only of parts, as in willow. Usually, other structures are present and serve to protect the sporophylls, the individual members of these surrounding structures are known as sepals and petals. The outer series is usually green and leaf-like, and functions to protect the rest of the flower, the inner series is, in general, white or brightly colored, and is more delicate in structure. It functions to attract insect or bird pollinators, attraction is effected by color and nectar, which may be secreted in some part of the flower

IUCN Red List
The IUCN Red List of Threatened Species, founded in 1964, is the worlds most comprehensive inventory of the global conservation status of biological species. The International Union for Conservation of Nature is the main authority on the conservation status of species. A series of Regional Red Lists are produced by countries or organizations, the IUCN Red List is set upon precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world, the aim is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to try to reduce species extinction. Major species assessors include BirdLife International, the Institute of Zoology, the World Conservation Monitoring Centre, assessments by these organizations and groups account for nearly half the species on the Red List. The IUCN aims to have the category of every species re-evaluated every five years if possible, the 1964 IUCN Red List of Threatened Plants used the older pre-criteria Red List assessment system.
Plants listed may not, appear in the current Red List, IUCN advise that is best to check both the online Red List and the 1997 plants Red List publication. The 2006 Red List, released on 4 May 2006 evaluated 40,168 species as a whole, plus an additional 2,160 subspecies, aquatic stocks, on 12 September 2007, the World Conservation Union released the 2007 IUCN Red List of Threatened Species. Russ Mittermeier, chief of Swiss-based IUCNs Primate Specialist Group, stated that 16,306 species are endangered with extinction,188 more than in 2006, the Red List includes the Sumatran orangutan in the Critically Endangered category and the Bornean orangutan in the Endangered category. The study shows at least 1,141 of the 5,487 mammals on Earth are known to be threatened with extinction, and 836 are listed as Data Deficient. The Red List of 2012 was released 19 July 2012 at Rio+20 Earth Summit, nearly 2,000 species were added, the IUCN assessed a total of 63,837 species which revealed 19,817 are threatened with extinction.
With 3,947 described as endangered and 5,766 as endangered. At threat are 41% of amphibian species, 33% of reef-building corals, 30% of conifers, 25% of mammals, the IUCN Red List has listed 132 species of plants and animals from India as Critically Endangered. Extinct – No known individuals remaining, extinct in the wild – Known only to survive in captivity, or as a naturalized population outside its historic range. Critically endangered – Extremely high risk of extinction in the wild, Endangered – High risk of extinction in the wild. Vulnerable – High risk of endangerment in the wild, near threatened – Likely to become endangered in the near future. Does not qualify for a more at-risk category and abundant taxa are included in this category. Data deficient – Not enough data to make an assessment of its risk of extinction, Not evaluated – Has not yet been evaluated against the criteria

Sussex
Sussex, from the Old English Sūþsēaxe, is a historic county in South East England corresponding roughly in area to the ancient Kingdom of Sussex. Brighton and Hove was created as an authority in 1997. Until then, Chichester was Sussexs only city, Sussex has three main geographic sub-regions, each oriented approximately east to west. In the south-west is the fertile and densely populated coastal plain, North of this are the rolling chalk hills of the South Downs, beyond which is the well-wooded Sussex Weald. The name derives from the Kingdom of Sussex, which was founded, according to legend, in 825, it was absorbed into the kingdom of Wessex and subsequently into the kingdom of England. It was the home of some of Europes earliest hominids, whose remains have been found at Boxgrove, in 1974, the Lord-Lieutenant of Sussex was replaced with one each for East and West Sussex, which became separate ceremonial counties. Sussex continues to be recognised as a territory and cultural region. It has had a police force since 1968 and its name is in common use in the media.
In 2007, Sussex Day was created to celebrate the rich culture. Based on the emblem of Sussex, a blue shield with six gold martlets. In 2013, Secretary of State for Communities and Local Government Eric Pickles formally recognised and acknowledged the existence of Englands 39 historic counties. The name Sussex is derived from the Middle English Suth-sæxe, which is in turn derived from the Old English Suth-Seaxe which means of the South Saxons, the South Saxons were a Germanic tribe that settled in the region from the North German Plain during the 5th and 6th centuries. The earliest known usage of the term South Saxons is in a charter of 689 which names them and their king, Noðhelm. The monastic chronicler who wrote up the entry classifying the invasion seems to have got his dates wrong, the New Latin word Suthsexia was used for Sussex by Dutch cartographer Joan Blaeu in his 1645 map. Three United States counties, and a former division of Western Australia, are named after Sussex. The flag of Sussex consists of six gold martlets, or heraldic swallows, on a background, blazoned as Azure.
Officially recognised by the Flag Institute on 20 May 2011, its design is based on the shield of Sussex. The first known recording of this emblem being used to represent the county was in 1611 when cartographer John Speed deployed it to represent the Kingdom of the South Saxons

Arthropod
An arthropod is an invertebrate animal having an exoskeleton, a segmented body, and jointed appendages. Arthropods form the phylum Arthropoda, which includes the insects, myriapods, arthropods are characterized by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages, the rigid cuticle inhibits growth, so arthropods replace it periodically by moulting. Their versatility has enabled them to become the most species-rich members of all guilds in most environments. They have over a million described species, making up more than 80% of all described living species, some of which. Arthropods range in size from the microscopic crustacean Stygotantulus up to the Japanese spider crab, arthropods primary internal cavity is a hemocoel, which accommodates their internal organs, and through which their haemolymph – analogue of blood – circulates, they have open circulatory systems. Like their exteriors, the organs of arthropods are generally built of repeated segments.
Their nervous system is ladder-like, with paired ventral nerve cords running through all segments and their heads are formed by fusion of varying numbers of segments, and their brains are formed by fusion of the ganglia of these segments and encircle the esophagus. The respiratory and excretory systems of arthropods vary, depending as much on their environment as on the subphylum to which they belong, arthropods have a wide range of chemical and mechanical sensors, mostly based on modifications of the many setae that project through their cuticles. Aquatic species use internal or external fertilization. Almost all arthropods lay eggs, but scorpions give birth to live young after the eggs have hatched inside the mother, arthropod hatchlings vary from miniature adults to grubs and caterpillars that lack jointed limbs and eventually undergo a total metamorphosis to produce the adult form. The level of care for hatchlings varies from nonexistent to the prolonged care provided by scorpions. The evolutionary ancestry of arthropods dates back to the Cambrian period, the group is generally regarded as monophyletic, and many analyses support the placement of arthropods with cycloneuralians in a superphylum Ecdysozoa.
Overall however, the relationships of Metazoa are not yet well resolved. Likewise, the relationships between various groups are still actively debated. Arthropods contribute to the food supply both directly as food, and more importantly indirectly as pollinators of crops. Some species are known to spread disease to humans, livestock. The word arthropod comes from the Greek ἄρθρον árthron, and πούς pous, i. e. foot or leg, arthropods are invertebrates with segmented bodies and jointed limbs

Dorset
Dorset /ˈdɔːrsᵻt/ is a county in South West England on the English Channel coast. The ceremonial county comprises the county, which is governed by Dorset County Council. Covering an area of 2,653 square kilometres, Dorset borders Devon to the west, Somerset to the north-west, Wiltshire to the north-east, the county town is Dorchester which is in the south. After the reorganisation of government in 1974 the countys border was extended eastward to incorporate the Hampshire towns of Bournemouth. Around half of the lives in the South East Dorset conurbation. The county has a history of human settlement stretching back to the Neolithic era. The Romans conquered Dorsets indigenous Celtic tribe, and during the early Middle Ages, the first recorded Viking raid on the British Isles occurred in Dorset during the eighth century, and the Black Death entered England at Melcombe Regis in 1348. During the Second World War, Dorset was heavily involved in the preparations for the invasion of Normandy, the former was the sailing venue in the 2012 Summer Olympics, and both have clubs or hire venues for sailing, Cornish pilot gig rowing, sea kayaking and powerboating.
Dorset has a varied landscape featuring broad elevated chalk downs, steep limestone ridges, over half the county is designated as an Area of Outstanding Natural Beauty. Three-quarters of its coastline is part of the Jurassic Coast Natural World Heritage Site due to its geological and it features notable landforms such as Lulworth Cove, the Isle of Portland, Chesil Beach and Durdle Door. Agriculture was traditionally the major industry of Dorset but is now in decline, there are no motorways in Dorset but a network of A roads cross the county and two railway main lines connect to London. Dorset has ports at Poole and Portland, and an international airport, the county has a variety of museums and festivals, and is host to one of Europes largest outdoor shows. It is the birthplace of Thomas Hardy, who used the county as the setting of his novels. Dorset derives its name from the county town of Dorchester, the Romans established the settlement in the 1st century and named it Durnovaria which was a Latinised version of a Common Brittonic word possibly meaning place with fist-sized pebbles.
It is first mentioned in the Anglo-Saxon Chronicle in AD845 and in the 10th century the countys archaic name, the first human visitors to Dorset were Mesolithic hunters, from around 8000 BC. The first permanent Neolithic settlers appeared around 3000 BC and were responsible for the creation of the Dorset Cursus, from 2800 BC onwards Bronze Age farmers cleared Dorsets woodlands for agricultural use and Dorsets high chalk hills provided a location for numerous round barrows. During the Iron Age, the British tribe known as the Durotriges established a series of forts across the county—most notably Maiden Castle which is one of the largest in Europe. The Romans arrived in Dorset during their conquest of Britain in AD43, Maiden Castle was captured by a Roman legion under the command of Vespasian, and the Roman settlement of Durnovaria was established nearby

Orchidaceae
The Orchidaceae are a diverse and widespread family of flowering plants, with blooms that are often colourful and often fragrant, commonly known as the orchid family. Along with the Asteraceae, they are one of the two largest families of flowering plants, the Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. The determination of which family is larger is still under debate, the number of orchid species nearly equals the number of bony fishes and is more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all seed plants, the largest genera are Bulbophyllum, Epidendrum and Pleurothallis. The family includes Vanilla and many cultivated plants such as Phalaenopsis. Moreover, since the introduction of species into cultivation in the 19th century, horticulturists have produced more than 100,000 hybrids. Orchids are easily distinguished from plants, as they share some very evident, shared derived characteristics.
Among these are, bilateral symmetry of the flower, many flowers, a nearly always highly modified petal, fused stamens and carpels. All orchids are perennial herbs that lack any permanent woody structure and they can grow according to two patterns, The stem grows from a single bud, leaves are added from the apex each year and the stem grows longer accordingly. The stem of orchids with a monopodial growth can reach several metres in length, as in Vanda, Sympodial orchids have a front and a back. The plant produces a series of adjacent shoots which grow to a size, bloom. Sympodial orchids grow laterally rather than vertically, following the surface of their support, the growth continues by development of new leads, with their own leaves and roots, sprouting from or next to those of the previous year, as in Cattleya. While a new lead is developing, the rhizome may start its growth again from a so-called eye, Sympodial orchids may have visible pseudobulbs joined by a rhizome, which creeps along the top or just beneath the soil.
Terrestrial orchids may be rhizomatous or form corms or tubers, the root caps of terrestrial orchids are smooth and white. Some sympodial terrestrial orchids, such as Orchis and Ophrys, have two subterranean tuberous roots, one is used as a food reserve for wintry periods, and provides for the development of the other one, from which visible growth develops. In warm and constantly humid climates, many terrestrial orchids do not need pseudobulbs, epiphytic orchids, those that grow upon a support, have modified aerial roots that can sometimes be a few meters long. In the older parts of the roots, a modified spongy epidermis and it is made of dead cells and can have a silvery-grey, white or brown appearance. In some orchids, the velamen includes spongy and fibrous bodies near the passage cells, the cells of the root epidermis grow at a right angle to the axis of the root to allow them to get a firm grasp on their support

Orchidoideae
The Orchidoideae, or the orchidoid orchids, are a subfamily of the orchid family. They typically contain the orchids with a single, fertile anther which is erect and it is sister to the tribe Diurideae. l. BATEMAN, PETER M. HOLLINGSWORTH, JILLIAN PRESTON, LUO YI-BO, ALEC M.

Monocotyledon
Monocotyledons, commonly referred to as monocots, are flowering plants whose seeds typically contain only one embryonic leaf, or cotyledon. However, molecular research has shown that while the monocots form a monophyletic group or clade. Monocots have almost always recognized as a group, but with various taxonomic ranks. The APG III system of 2009 recognises a clade called monocots, the monocots include about 60,000 species. The largest family in this group by number of species are the orchids, about half as many species belong to the true grasses, which are economically the most important family of monocots. In agriculture the majority of the biomass produced comes from monocots and these include not only major grains, but forage grasses, sugar cane, and the bamboos. Other economically important monocot crops include various palms, bananas and their relatives and cardamom, asparagus and the onions and garlic family. Additionally most of the bulbs, plants cultivated for their blooms, such as lilies, irises, cannas, bluebells.
The monocots or monocotyledons have, as the name implies, a single cotyledon, or embryonic leaf, from a diagnostic point of view the number of cotyledons is neither a particularly useful characteristic, nor is it completely reliable. Nevertheless, monocots are sufficiently distinctive that there has rarely been disagreement as to membership of this group, morphological features that reliably characterise major clades are rare. Thus monocots are distinguishable from other angiosperms both in terms of their uniformity and diversity, although largely herbaceous, some arboraceous monocots reach great height and mass. The latter include agaves, palms and bamboos and this creates challenges in water transport that monocots deal with in various ways. Some such as species of Yucca develop anomalous secondary growth, while palm trees, the axis undergoes primary thickening, that progresses from internode to internode, resulting in a typical inverted conical shape of the basal primary axis. The limited conductivity contributes to limited branching of the stems, despite these limitations a wide variety of adaptive growth forms has resulted from epiphytic orchids and bromeliads to submarine Alismatales and mycotrophic Burmanniaceae and Triuridaceae.
Other monocots, particularly Poales have adopted a life form. Leaves The cotyledon, the primordial Angiosperm leaf consists of a proximal leaf base or hypophyll, in moncots the hypophyll tends to be the dominant part in contrast to other angiosperms. Mature monocot leaves are narrow and linear, forming a sheathing around the stem at its base. There is usually only one leaf per node because the leaf base encompasses more than half the circumference, the evolution of this monocot characteristic has been attributed to developmental differences in early zonal differentiation rather than meristem activity

Andrena
Andrena, commonly called the mining bee, is the largest genus in the family Andrenidae, and is nearly worldwide in distribution, with the notable exceptions of Oceania and South America. With over 1,300 species, it is one of the largest of all bee genera, Species are often brown to black with whitish abdominal hair bands, though other colors are possible, most commonly reddish, but including metallic blue or green. Body length commonly ranges between 8 –17 mm with males smaller and more slender than females, which show a black triangle at the abdominal apex. In temperate areas, Andrena bees emerge from the cells where their prepupae spend the winter. Andrena usually prefer sandy soils for a substrate, near or under shrubs to be protected from heat. Andrena females can be distinguished from most other small bees by the possession of broad velvety areas in between the compound eyes and the antennal bases, called facial foveae. They tend to have very long hairs on the trochanters of the hind leg. C. D.
