Scrophularia Oblongifolia
''Scrophularia oblongifolia'' (syn. ''S. umbrosa''), green figwort, is a Perennial plant, perennial herbaceous plant found in Europe and Asia. It grows in damp, shady places such as wet woodland and farmland ditches. It is very similar to the closely related ''Scrophularia auriculata'' (water figwort), from which it is best separated by the shape of the staminode. Description Green figwort is a Raunkiær plant life-form, hemicryptophyte perennial monoecious herb with no basal rosette and a short rhizome, which grows to about 100 cm tall. The whole plant is a rather pale green colour, sometimes with a hint of brown or purple, and completely glabrous (hairless). The stem is square in section, with broad wings at the angles, and generally rather weak, causing the plant to sprawl over vegetation rather than growing upright on its own. The leaves are arranged in opposite pairs on petioles up to 15 mm long, with an ovate to oblong blade of about 12 × 4 cm and a fairly pointed tip, w ...

Perennial Plant
In horticulture, the term perennial (''wikt:per-#Prefix, per-'' + ''wikt:-ennial#Suffix, -ennial'', "through the year") is used to differentiate a plant from shorter-lived annual plant, annuals and biennial plant, biennials. It has thus been defined as a plant that lives more than 2 years. The term is also loosely used to distinguish plants with little or no woody growth (secondary growth in Tree girth measurement, girth) from trees and shrubs, which are also technically ''perennials''. Notably, it is estimated that 94% of plant species fall under the category of perennials, underscoring the prevalence of plants with lifespans exceeding two years in the botanical world. Perennials (especially small flowering plants) that grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as Herbaceous plant, herbaceous perennials. However, depending on the rigours of the loca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycobacterial Cervical Lymphadenitis
The disease mycobacterial cervical lymphadenitis, also known historically as scrofula and the king's evil, involves a lymphadenitis of the cervical (neck) lymph nodes associated with tuberculosis as well as nontuberculous (atypical) mycobacteria such as ''Mycobacterium marinum''. Disease Scrofula is the term used for lymphadenopathy of the neck, usually as a result of an infection in the lymph nodes known as lymphadenitis. It can be caused by tuberculous or nontuberculous mycobacteria. About 95% of the scrofula cases in adults are caused by ''Mycobacterium tuberculosis'', most often in immunocompromised patients (about 50% of cervical tuberculous lymphadenopathy). In immunocompetent children, scrofula is often caused by atypical mycobacteria ('' Mycobacterium scrofulaceum)'' and other nontuberculous mycobacteria (NTM). Unlike the adult cases, only 8% of cases in children are tuberculous. With the stark decrease of tuberculosis in the second half of the 20th century, scrofula beca ...

British NVC Community W8
__NOTOC__ NVC community W8 (''Fraxinus excelsior - Acer campestre - Mercurialis perennis'' woodland) is one of the woodland communities in the British National Vegetation Classification system. It is one of the six communities falling in the "mixed deciduous and oak/birch woodlands" group. This is a widely distributed community. There are seven subcommunities. Community composition Six constant species are found in this community: * Field Maple (''Acer campestre'') * Hazel (''Corylus avellana'') * Ash (''Fraxinus excelsior'') * Dog's-mercury (''Mercurialis perennis'') * Bramble (''Rubus fruticosus'' agg.) * Common Feather-moss (''Eurhynchium praelongum'') The following rare species are also associated with the community: * Narrow-leaved Bittercress (''Cardamine impatiens'') * Mezereon (''Daphne mezereum'') * Wood Fescue (''Festuca altissima'') * Mountain Currant (''Ribes alpinum'') * Oxlip (''Primula elatior'') * ''Primula × digenea'', the hybrid between Oxlip and Primro ...

Carex Otrubae
''Carex otrubae'', the false fox-sedge, is a species of flowering plant in the sedge family, Cyperaceae. Description It grows tall with the leaves being linear and wide. Both inflorescence and lanceolate are long. Its utricles are either pale green or orange-brown. Female specimens have pale orange-brown glumes which are ovate and are in length. Distribution and habitat This species occurs in Europe, Central Asia, West Siberia, and Xinjiang, China China, officially the People's Republic of China (PRC), is a country in East Asia. With population of China, a population exceeding 1.4 billion, it is the list of countries by population (United Nations), second-most populous country after .... It thrives in wetlands on heavy soils and especially in lowland areas and can be found near lakes, rivers and reservoirs, as well as coastal areas.

Axiophyte
An axiophyte (Greek: "worthy plant") is a plant that is of particular interest to botanists, conservationists and ecologists. The significance of axiophytes is from their strong association with habitats considered to be of high merit for conservation. Axiophytes are a relatively recent concept which has its roots in such ideas as "ancient woodland indicator species". According to the Botanical Society of Britain and Ireland (BSBI), around 40% of plant species can be considered axiophytes. Very rare species are not considered axiophytes; for a species to be a useful indicator of quality habitat it must be relatively frequent in those habitats, but scarce elsewhere. A typical example would be dog's mercury (''Mercurialis perennis''), a plant slow to colonise new sites, but common in ancient woodland and old hedgerows. The number of axiophytes on a site provides a crude, but convenient, measure of its nature conservation importance. It is a particularly useful approach when compar ...
