Wardia
''Wardia'' is a monotypic genus of mosses in the subclass Dicranidae; it contains only the species ''Wardia hygrometrica'', "an aquatic moss endemic to the Western Cape province of South Africa."Hedderson, Terry A., Cymon J. Cox, & J. George Gibbins. 1999. Phylogenetic Relationships of the Wardiaceae (Musci); Evidence from 18s rRNA and rps4 Gene Sequences. ''The Bryologist'' 102 (1): 26-31. It is the only endemic moss family in South Africa. As it is an aquatic moss, it was first classified in the Fontinalaceae (and in the order of Isobryales), but molecular studies have shown that it is more closely related to the Dicranaceae. The genus name of ''Wardia'' is in honour of Nathaniel Bagshaw Ward (1791–1868), who was an English doctor.The specific epithet ''hygrometrica'' refers to the hygroscopic nature of the seta (stalk). The genus was circumscribed by William Henry Harvey William Henry Harvey, FRS FLS (5 February 1811 – 15 May 1866) was an Irish botanist and ...

Nathaniel Bagshaw Ward
Nathaniel Bagshaw Ward (1791 – 4 June 1868 in St Leonard's, Sussex) was an English doctor who popularised a case for growing and transporting plants which was called the Wardian case. Biography Ward was born in London to Stephen Smith Ward, a medical doctor. Little is known of his early years and family life, but he is believed to have been sent to Jamaica at the age of thirteen where he may have taken an interest in plants. He practised medicine in a poor area of the East End of London and took an interest in botany and entomology in spare time or when on vacation in Cobham, Kent. Tytler Whittle in his book, ''The Plant Hunters'', describes the area where he lived: Ward qualified as a member of the Royal College of Surgeons in London in 1814, then later became a fellow of the Linnean Society in 1852. His four sons, Stephen (born 1819), Nathaniel (born 1821), John (born 1824) and Richard (born 1831) all went on to qualify as doctors and surgeons. Stephen and Nathaniel ...

Dicranaceae
Dicranaceae is a family of haplolepideous mosses (Dicranidae) in class Bryopsida. Species within this family are dioicous Dioicy () is a sexual system where archegonia and antheridia are produced on separate gametophytes. It is one of the two main sexual systems in bryophytes. Both dioicous () and monoicous gametophytes produce gametes in gametangia by mitosis ra .... Genera in this family include '' Dicranum'', '' Dicranoloma'', and '' Mitrobryum''. Classification The family Dicranaceae contains the following genera: *'' Anisothecium'' *'' Aongstroemia'' *'' Aongstroemiopsis'' *'' Braunfelsia'' *'' Brotherobryum'' *'' Bryotestua'' *'' Camptodontium'' *'' Campylopodium'' *'' Chorisodontium'' *'' Cnestrum'' *'' Cryptodicranum'' *'' Dicnemon'' *'' Dicranella'' *'' Dicranoloma'' *'' Dicranum'' *'' Diobelonella'' *'' Eucamptodon'' *'' Eucamptodontopsis'' *'' Holomitriopsis'' *'' Holomitrium'' *'' Hygrodicranum'' *'' Leptotrichella'' *'' Leucoloma'' *' ...

Isobryales
Isobryales are an order of mosses. Its taxonomic status is not clear. The Integrated Taxonomic Information System and National Center for Biotechnology Information databases consider it as a synonym of Bryidae and Hypnales, respectively. The Global Biodiversity Information Facility considers it valid in its own right. Genera As accepted by GBIF; * Cyrtopodaceae (8) * Fontinalaceae (94) * Glyphomitriaceae (1) * Hydropogonaceae (4) * Lepyrodontaceae(13) * Prionodontaceae (21) * Ptychomniaceae (44) * Regmatodontaceae (29) * Rhacocarpaceae (1) * Rutenbergiaceae (11) * Trachypodaceae (80) * Wardiaceae (2) Figures in brackets are approx. how many species per genus. Description The order includes plants that generally grow from a creeping primary stem with reduced leaves, and plants that have spreading to ascending secondary stems which may be pinnately branched. Paraphyllia (tiny branched or stipuliform organs between the leaves) and pseudoparaphyllia are sometimes pres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

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 ...

Dicranidae
The Dicranidae are a widespread and diverse subclass of mosses in class Bryopsida, with many species of dry or disturbed areas. They are distinguished by their spores; the peristome Peristome (from the Greek ''peri'', meaning 'around' or 'about', and ''stoma'', 'mouth') is an anatomical feature that surrounds an opening to an organ or structure. Some plants, fungi, and shelled gastropods have peristomes. In mosses In mosses, ... teeth are haplolepideous with a 4:2:3 formula, and an exostome is absent.

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg. About 80% of the population are Black South Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

William Henry Harvey
William Henry Harvey, FRS FLS (5 February 1811 – 15 May 1866) was an Irish botanist and phycologist who specialised in algae. Biography Harvey was born at Summerville near Limerick, Ireland, in 1811, the youngest of 11 children. His father Joseph Massey Harvey, was a Quaker and prominent merchant. William started his education at Ballitore School in County Kildare and by the age of 15 had already established algae as his over-riding interest.Papenfuss, G.F. 1976. pp.21–46. Landmarks in Pacific North American Marine Phycology. ''in'' Abbott, I.A. and Hollenberg, G.J. 1976. ''Marine Algae of California''. Stanford University Press, California. After leaving school he joined the family business.
