Cors Llyn Farch A Llyn Fanod
Llyn Fanod is an upland lake situated between Penuwch and Bontnewydd in Ceredigion, Wales. It is a Site of Special Scientific Interest partly owned by the Wildlife Trust of South and West Wales. Public access is via a bridlepath from the road. It is a mesotrophic lake located in the headwaters of the River Aeron, whose low nutrient waters are home to a number of locally rare water plants. Waterfowl and passing sea birds can be seen on the lake as can dragonflies, damselflies, and caddis flies in the summer. The lake has a surface area of and a maximum depth of . It lies in a hollow probably scoured out glacially, and is dammed by a moraine. Palynological studies show that it has developed since the last ice age and is a remnant of a larger lake, Llyn Farch, which has otherwise dried up. It is surrounded by pasture grazed by cattle and sheep and at the southern end is a small peat mire. There are tussocks of purple moor-grass and tall cushions of common hair moss and ''Sphagnum ...

Ceredigion
Ceredigion ( , , ) is a county in the west of Wales, corresponding to the historic county of Cardiganshire. During the second half of the first millennium Ceredigion was a minor kingdom. It has been administered as a county since 1282. Ceredigion is considered a centre of Welsh culture and just under half of the population can speak Welsh according to the 2011 Census. The county is mainly rural, with over of coastline and a mountainous hinterland. The numerous sandy beaches and the long-distance Ceredigion Coast Path provide views of Cardigan Bay. In the 18th and early 19th centuries, Cardiganshire had more industry than it does today; Cardigan was the commercial centre of the county; lead, silver and zinc were mined and Cardigan was the principal port of South Wales prior to the silting of its harbour. The economy became highly dependent on dairy farming and the rearing of livestock for the English market. During the 20th century, livestock farming became less profitable ...

Palynology
Palynology is the "study of dust" (from grc-gre, παλύνω, palynō, "strew, sprinkle" and '' -logy'') or of "particles that are strewn". A classic palynologist analyses particulate samples collected from the air, from water, or from deposits including sediments of any age. The condition and identification of those particles, organic and inorganic, give the palynologist clues to the life, environment, and energetic conditions that produced them. The term is commonly used to refer to a subset of the discipline, which is defined as "the study of microscopic objects of macromolecular organic composition (i.e., compounds of carbon, hydrogen, nitrogen and oxygen), not capable of dissolution in hydrochloric or hydrofluoric acids". It is the science that studies contemporary and fossil palynomorphs (paleopalynology), including pollen, spores, orbicules, dinocysts, acritarchs, chitinozoans and scolecodonts, together with particulate organic matter (POM) and kerogen found in sedimen ...

Isoetes Lacustris
''Isoetes lacustris'', the lake quillwort or Merlin's grass, is a boreal quillwort native on both sides of the northern Atlantic Ocean. Synonyms include ''Isoetes hieroglyphica''. Description The lake quillwort has many long, narrow leaves from 8–20 cm long and 0.5–2 mm broad, widening to 5 mm broad at the base. There is a sac that produces the spores at the bottom of each leaf base. The plant has a very short stem, called a corm, where all the leaves and roots are attached close together. It does not have traditional roots, but instead some of its leaves are modified to act like roots. These pseudo-roots are called rhizomorphs, and are attached to the bottom end of corm. The upper leaves are green and found sprouting in a clump. Reproduction usually takes place during the late summer or early fall. The sacs at the bottom of leaves create two types of spores, female (megaspores, about 0.5 mm diameter) and male (microspores, a few micrometres in diamete ...

Lobelia Dortmanna
''Lobelia dortmanna'', Dortmann's cardinalflower or water lobelia, is a species of flowering plant in the bellflower family Campanulaceae. This stoloniferous herbaceous perennial aquatic plant with basal leaf-rosettes and flower stalks grows to tall. The flowers are 1–2 cm long, with a five-lobed white to pale pink or pale blue corolla, produced in groups of one to ten on an erect raceme held above the water surface. The fruit is a capsule 5–10 mm long and 3–5 mm wide, containing numerous small seeds.BorealForest''Lobelia dortmanna''/ref>Blamey, M. & Grey-Wilson, C. (1989). ''Flora of Britain and Northern Europe''. The leaves are almost cylindrical, blunt, 2.5–7.5 cm long and evergreen. They have no functional stomata. It is one of several unrelated species of plants from low nutrient lakes known as isoetids, owing to their superficial similarity to Isoetes. The leaves of ''Lobelia dortmanna'' are, however, easily distinguishable from those of othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nymphaea Alba
''Nymphaea alba'', the white waterlily, European white water lily or white nenuphar , is an aquatic flowering plant in the family Nymphaeaceae. It is native to North Africa, temperate Asia, Europe and tropical Asia (Jammu and Kashmir). Description It grows in water that is deep and likes large ponds and lakes. The leaves can be up to in diameter and take up a spread of per plant. The flowers are white and they have many small stamens inside. Taxonomy It was first published and described by Carl Linnaeus in his book 'Species Plantarum', on page 510 in 1753. The red variety (''Nymphaea alba'' f. ''rosea'') is cultivated from lake Fagertärn ("Fair tarn") in the forest of Tiveden, Sweden, where it was discovered in the early 19th century. The discovery led to large-scale exploitation which nearly made it extinct in the wild before it was protected. ''Nymphaea candida'' is sometimes considered a subspecies of ''N. alba'' (''N. alba'' L. subsp. ''candida'' ). Distribution an ...

Nuphar Lutea
''Nuphar lutea'', the yellow water-lily, brandy-bottle, or spadderdock, is an aquatic plant of the family ''Nymphaeaceae'', native to northern temperate and some subtropical regions of Europe, northwest Africa, western Asia, North America, and Cuba. This interesting species found on both sides of the Atlantic Ocean was used as a food source and in medicinal practices from prehistoric times with potential research and medical applications going forward. Botanical description and etymology ''Nuphar lutea’s'' wide distribution and long-standing interest as an object of food, medicine, horticulture and folklore has led to many common or popular names. The following list is testimony to this species’ long history: This species’ botanical name "''Nuphar lutea'' (L.) Sm." includes its scientific name (''Nuphar lutea''), genus (''Nuphar''), specific epithet (''lutea''), a standard author abbreviation for Carl Linnaeus (L.), and an author citation for James Edward Smith (Sm.) ...

Sphagnum
''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, peat moss, also bog moss and quacker moss (although that term is also sometimes used for peat). Accumulations of ''Sphagnum'' can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 to 26 times as much water as their dry weight, depending on the species.Bold, H. C. 1967. Morphology of Plants. second ed. Harper and Row, New York. p. 225-229. The empty cells help retain water in drier conditions. As sphagnum moss grows, it can slowly spread into drier conditions, forming larger mires, both raised bogs and blanket bogs. Thus, sphagnum can influence the composition of such habitats, with some describing sphagnum as 'habitat manipulators'. These peat accumulations then provide habitat for a wide array of peatland plants, including sedges and Calcifuges, ericaceous shrubs, as well as orchids and carnivorous plant ...

Menyanthes
''Menyanthes'' is a monotypic genus of flowering plants in the family Menyanthaceae containing the single species ''Menyanthes trifoliata''. The North American form is often referred to as ''M. trifoliata'' var. ''minor'' Michx. It is known in English by the common names bogbean and buckbean. Description ''Menyanthes trifoliata'' has a horizontal rhizome with alternate, trifoliate leaves. The inflorescence is an erect raceme of white flowers. The species occurs in fens and bogs in Asia, Europe, and North America. In eastern North America, it is considered to be a diagnostic fen species. It sometimes creates big quagmires with its thick roots. Taxonomy The name ''Menyanthes'' comes from the Greek words ''menyein'', meaning "disclosing", and ''anthos'', meaning "flower", in reference to the sequential opening of flowers on the inflorescence. Fossil record One fossil seed of ''Menyanthes trifoliata'' has been extracted from borehole samples of the Middle Miocene fresh wa ...

Narthecium Ossifragum
''Narthecium ossifragum'', commonly known as bog asphodel, Lancashire asphodel or bastard asphodel, is a species of flowering plant in the family Nartheciaceae. It is native to Western Europe, found on wet, boggy moorlands up to about in elevation. It produces spikes of bright yellow flowers in summer. The bright orange fruits have been used as a colourant to replace saffron by Shetland Islanders.Richard Mabey ''Flora Britannica'' Despite the plant's English name "bog asphodel", it is not particularly closely related to the true asphodels. In addition to other forms of pollination, this plant is adapted to rain-pollination. The Latin specific name ''ossifragum'' means "bone-breaker", and refers to a traditional belief that eating the plant caused sheep to develop brittle bones. The probable origin of this story is that sheep eating a calcium-poor diet are likely to develop bone weakness, and ''N. ossifragum'' favours acidic low-calcium soils.

Comarum Palustre
''Comarum palustre'' ( syn. ''Potentilla palustris''), known by the common names purple marshlocks, swamp cinquefoil and marsh cinquefoil, is a common waterside shrub. It has a circumboreal distribution, occurring throughout North America, Europe, and Asia, particularly the northern regions. It is most commonly found on lake shores, marshy riversides and stream margins, often partly submerged with foliage floating. It is a parent of some ''Fragaria''–''Comarum'' hybrids, ornamental plants produced by crossing with strawberries. Description Its branches spread into leaves with three to seven narrow leaflets which are sharply jagged. The stem is a reddish-brown, low sprawling, vine-like structure. Flowers extend from the branch which vary from red to purple, and are about one inch in diameter, blooming in summer. The stems roots at the base then rises to about .Parnell, J. and Curtis, T. 2012.
