Dryopteris Affinis
''Dryopteris affinis'', the scaly male fern or golden-scaled male fern, is a fern native to western and southern Europe and southwestern Asia. It is most abundant on moist soils in woodlands in areas with high humidity, such as the British Isles and western France. In the Mediterranean region and the Caucasus it is confined to high altitudes. Description ''Dryopteris affinis'' is virtually evergreen and bears light green fronds long, moderately stiff and hard-textured, the rachis at the base of the frond densely covered in yellow-brown scales known as ramenta. The frond is bipinnate, the pinnae up to long, the pinnules broad rectangular with the margin most toothed close to the pinna tip. There is a blackish spot at the base of the pinna where it joins the rachis. Individual fronds live for about 1.5 years and remain attached to the rhizome after withering. ''D. affinis'' is closely related to ''Dryopteris filix-mas'', distinguished by its usually more robust habit with usually ...

Richard Thomas Lowe
Richard Thomas Lowe (1802–1874) was an English botanist, ichthyologist, malacologist, and clergyman. In 1825 he graduated from Christ's College, Cambridge, and in the same year he took holy orders. In 1832 he became a clergyman in the Madeira Islands, where he was also a part-time naturalist, extensively studying the local flora and fauna. He wrote a book on the Madeiran flora. He died in 1874 when the ship he was on was wrecked off the Isles of Scilly. Taxa Lowe named and described numerous molluscan taxa, including: * '' Caseolus'', a land snail genus and eight species within it * '' Lemniscia'', a land snail A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails.

Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in ) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, ''Escobaria vivipara'', is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. Definitions The term is defined in different ways by different authors. However, the International Code of Nomenclature for Cultivated Plants, while recognizing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of England
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms '' gut flora'' or '' skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) ...

Flora Of Iran
The wildlife of Iran include the fauna and flora of Iran. One of the most famous animals of Iran is the critically endangered Asiatic cheetah (''Acinonyx jubatus venaticus''), which today survives only in Iran. Another notable species is the Iranian ground jay (''Podoces pleskei''), the only bird endemic to Iran. History The animals of Iran were described by Hamdallah Mustawfi in the 14th century. In the 18th and 19th centuries, Samuel Gottlieb Gmelin and Édouard Ménétries explored the Caspian Sea area and the Talysh Mountains to document Caspian fauna. Several naturalists followed in the 19th century, including Filippo de Filippi, William Thomas Blanford, and Nikolai Zarudny who documented mammal, bird, reptile, amphibian and fish species. The Complete Fauna of Iran by Eskandar Firouz, documents a wide range of species across the country’s ecosystems Flora More than one-tenth of the country is forested. The most extensive forest is found on the mountain slopes rising from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferns Of Europe
The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate ( Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns. The fern crown group, consisting of the leptosporangiates and eusporangiates, is estimated to have originated in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. It includes the full range of cultivated plants, from annuals, biennials and perennials to shrubs and trees. It covers plants grown for specific purposes - such as vegetable crops, fruit, hedging, topiary, groundcover, summer bedding, houseplants, etc. It tests characteristics such as robustness, hardiness, longevity, flowering/fruiting abundance and quality, usefulness, and ease of cultivation. It pays particular attention to a plant's ability to survive and thrive in challenging conditions such as wind and frost. The AGM trophy symbol is widely used in gardening literature as a sign of exceptional quality, and is recognised as such by writers, horticulturalists, nurseries, and everybody in the UK who practises gardening.

Cultivars
A cultivar is a kind of cultivated plant that people have selected for desired traits and which retains those traits when propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in '' Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated ...

Christopher Roy Fraser-Jenkins
Christopher is the English version of a Europe-wide name derived from the Greek name Χριστόφορος (''Christophoros'' or '' Christoforos''). The constituent parts are Χριστός (''Christós''), "Christ" or "Anointed", and φέρειν (''phérein''), "to bear"; hence the "Christ-bearer". As a given name, 'Christopher' has been in use since the 10th century. In English, Christopher may be abbreviated as "Chris", "Topher", and sometimes " Kit". It was frequently the most popular male first name in the United Kingdom, having been in the top twenty in England and Wales from the 1940s until 1995, although it has since dropped out of the top 100. Within the United Kingdom, the name is most common in England and not so common in Wales, Scotland, or Northern Ireland.
