Chyenhal Moor
Chyenhal Moor is a poorly drained shallow valley, to the south-west of Penzance, Cornwall. Due to several rare plants in a diverse range of habitats, it was notified as a Site of Special Scientific Interest (SSSI) in 1951. Geography Chyenhal Moor is a poorly drained shallow valley in the parish of Paul, on the southern side of the Land's End peninsula. The small stream draining the moor flows to Kerris Moor and reaches the sea at Lamorna Cove. The underlying rock is coarsely porphyritic granite and the soils are mostly humic, gleys, covered with varying depths of peat. History Until the early 19th-century rough-ground such as Chyenhal Moor was an important part of the rural economy, through the grazing of livestock and cutting of furze (gorse) for fuel. Moorland usually refers to uncultivated land on a hill, but locally it is also applied to wetlands such as this, and the nearby Kerris and Clodgy Moors. The high rainfall, poor drainage and acid conditions inhibit the action ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Ralfs
John Ralfs (13 September 1807 – 14 July 1890) was an English botanist. Born in Millbrook, near Southampton, he was the second son of Samuel Ralfs, a yeoman of an old family in Hampshire. He has been commemorated in the names of many plant groups and taxa at many levels. Early life and education Ralfs's father died at Mudeford near Christchurch before John was a year old, and the children (two sons and two daughters) were brought up at Southampton by their mother. After being educated privately he was articled to his uncle, a surgeon of Brentford, with whom he lived for two years and a half. For two years he was a pupil at Winchester Hospital, and in 1832 he passed his final examination, being specially recommended by the examiners for his knowledge of botany. For some time he practised in partnership with another surgeon at Shoreditch, and he is also said to have practised at Towcester. At Torquay, where he moved on account of lung disease (probably tubercular in origin), he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are a ...

Cirsium Palustre
''Cirsium palustre'', the marsh thistle or European swamp thistle, is a herbaceous biennial (or often perennial) flowering plant in the family Asteraceae. ''Cirsium palustre'' is a tall thistle which reaches up to in height. The strong stems have few branches and are covered in small spines. In its first year the plant grows as a dense rosette, at first with narrow, entire leaves with spiny, dark purple edges; later, larger leaves are lobed. In the subsequent years the plant grows a tall, straight stem, the tip of which branches repeatedly, bearing a candelabra of dark purple flowers, with purple-tipped bracts. In the northern hemisphere these are produced from June to September. The flowers are occasionally white, in which case the purple edges to the leaves are absent. The plant provides a great deal of nectar for pollinators. It was rated first out of the top 10 for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand pr ...
