Barberetta
''Barberetta'' is a genus of herbaceous perennial plants in the family Haemodoraceae. It contains only one known species, ''Barberetta aurea''. Description ''Barberetta aurea'' grows to up to high from a tuberous rootstock and develops about 3 leaves that are arranged like a fan, flattened sideways and so creating a left and right surface rather than an upper and lower surface. The leaves lack a leafstalk, are lance-shaped in outline, hairless, up to long and wide at midlength, narrowing gradually to the foot and the tip, and have five distinct vertical ribs and several finer ribs in between. The stem is weak, long, with some hairs towards the top, and carries its many flowers in a simple raceme, of long. The stalks of the individual flower are inclined upwards, the lower flower stalks are long. Wrapped around the foot of each flower stalk is a persistent lance-shaped bract of up to long. The star-symmetric perianth consists of six tepals of about long and wide, that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lachnanthes
''Lachnanthes'' is a genus of monocotyledonous plants in the bloodwort family containing only one species, i.e., ''Lachnanthes caroliniana'', commonly known as Carolina redroot or bloodroot. The plant is native to eastern North America, from southeastern Nova Scotia (especially the Molega Lake area) and Massachusetts in the north, south to Florida and Cuba, and west along the Gulf of Mexico to Louisiana. It has also been reported from an island in the western Caribbean off the coast of Honduras. It prefers wet, acidic, usually sandy soils, restricting it to various wetland habitats such as bogs, pinelands, hammocks and pocosins, among others. The plant's common name is based on its red roots and rhizomes. Its flowers, consisting of six pale yellow tepals, emerge from mid to late summer. The plant is sometimes a significant weed in commercial cranberry Cranberries are a group of evergreen dwarf shrubs or trailing vines in the subgenus ''Oxycoccus'' of the genus ''Vaccin ...

Haemodoraceae
Haemodoraceae is a family of perennial herbaceous flowering plants with 14 genera and 102 known species. It is sometimes known as the "bloodwort family". Primarily a Southern Hemisphere family, they are found in South Africa, Australia and New Guinea, and in the Americas (from SE U.S.A. to tropical South America). Perhaps the best known are the widely cultivated and unusual kangaroo paws from Australia, of the two closely related genera '' Anigozanthos'' and '' Macropidia''. Taxonomy The Haemodoraceae were first described by Robert Brown in 1810, and bear his name as the botanical authority. An alternative name has been Haemodoreae The fourth Angiosperm Phylogeny Group classification of 2016 (unchanged from the earlier APG systems of 2009, 2003 and 1998), also recognizes this family and places it in the order Commelinales, in the clade commelinids, in the monocots. The family of the Haemodoraceae then includes about sixteen sub-tropical or tropical genera found in the sout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chirality
Chirality is a property of asymmetry important in several branches of science. The word ''chirality'' is derived from the Greek (''kheir''), "hand", a familiar chiral object. An object or a system is ''chiral'' if it is distinguishable from its mirror image; that is, it cannot be superimposed onto it. Conversely, a mirror image of an ''achiral'' object, such as a sphere, cannot be distinguished from the object. A chiral object and its mirror image are called ''enantiomorphs'' (Greek, "opposite forms") or, when referring to molecules, '' enantiomers''. A non-chiral object is called ''achiral'' (sometimes also ''amphichiral'') and can be superposed on its mirror image. The term was first used by Lord Kelvin in 1893 in the second Robert Boyle Lecture at the Oxford University Junior Scientific Club which was published in 1894: Human hands are perhaps the most recognized example of chirality. The left hand is a non-superimposable mirror image of the right hand; no matter ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wachendorfia
''Wachendorfia'' is a genus of perennial herbaceous plants that is assigned to the bloodroot family. The plants have a perennial rootstock with red sap. From the rootstock emerge lance- or line-shaped, sometime sickle-shaped, pleated, simple leaves set in a fan, that are flattened to create a left and right surface rather than an upper and lower surface. The leaves die when the seeds are shed in three of the species, and are perennial in one species. The rootstock also produces flowering stems annually that carry a panicle of zygomorphic, yellow or yellowish flowers in two distinct forms, one with the style and one stamen bent to the right and two stamens to the left, and vice versa. The fruit opens with three valves and each contains a single, hairy seed. All species only occur in the fynbos biome in the Cape provinces of South Africa. Description ''Wachendorfia'' is a genus of perennial herbaceous plants of high when flowering, which emerge from a fleshy, bright red-colou ...

Dilatris
''Dilatris'' is a genus of four species of evergreen perennial herbaceous plants of up to high, that are assigned to the bloodroot family. The plants have hairless, line- to lance-shaped leaves set in a fan that emerges from a red or orange coloured rootstock. The mauve or dirty yellow flowers have six free tepals that have some gland dots near their tips. One stamen is short, upright, with a large, yellow anther, the other two are longer, spreading, with smaller scarlet anthers. The style is diverted from the centre opposite both longer stamens. The species only occur in the Western Cape and Northern Cape provinces of South Africa. Description The species of ''Dilatris'' are evergreen, perennial herbaceous plants with a short underground rootstock that is bright red or orange inside. From the rootstock emerge several hairless, line- to oblong lance-shaped leaves that are laterally flattened resulting in a right and left surface rather than an upper and lower surface. The infl ...

Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Outcrossing
Out-crossing or out-breeding is the technique of crossing between different breeds. This is the practice of introducing distantly related genetic material into a breeding line, thereby increasing genetic diversity. Outcrossing can be a useful technique in Animal husbandry, animal breeding. The outcrossing breeder intends to remove the traits by using "new blood." With dominant traits, one can still see the expression of the traits and can remove those traits whether one outcrosses, line breeds or inbreeds. With recessive traits, outcrossing allows for the recessive traits to migrate across a population. Many traits are Mendelian and therefore exhibit a more complicated intermediate phenotype. The outcrossing breeder then may have individuals that have many deleterious genes that may be expressed by subsequent inbreeding. There is now a gamut of deleterious genes within each individual in many dog breeds. Increasing the variation of genes or alleles within the gene pool may pro ...

KwaZulu-Natal
KwaZulu-Natal (, also referred to as KZN and known as "the garden province") is a province of South Africa that was created in 1994 when the Zulu bantustan of KwaZulu ("Place of the Zulu" in Zulu) and Natal Province were merged. It is located in the southeast of the country, with a long shoreline on the Indian Ocean and sharing borders with three other provinces and the countries of Mozambique, Eswatini and Lesotho. Its capital is Pietermaritzburg, and its largest city is Durban. It is the second-most populous province in South Africa, with slightly fewer residents than Gauteng. Two areas in KwaZulu-Natal have been declared UNESCO World Heritage Sites: the iSimangaliso Wetland Park and the uKhahlamba Drakensberg Park. These areas are extremely scenic as well as important to the surrounding ecosystems. During the 1830s and early 1840s, the northern part of what is now KwaZulu-Natal was established as the Zulu Kingdom while the southern part was, briefly, the Boer Natalia Repu ...

Eastern Cape
The Eastern Cape is one of the provinces of South Africa. Its capital is Bhisho, but its two largest cities are East London and Gqeberha. The second largest province in the country (at 168,966 km2) after Northern Cape, it was formed in 1994 out of the Xhosa homelands or bantustans of Transkei and Ciskei, together with the eastern portion of the Cape Province. The central and eastern part of the province is the traditional home of the indigenous Xhosa people. In 1820 this area which was known as the Xhosa Kingdom began to be settled by Europeans who originally came from England and some from Scotland and Ireland. Since South Africa's early years, many Xhosas believed in Africanism and figures such as Walter Rubusana believed that the rights of Xhosa people and Africans in general, could not be protected unless Africans mobilized and worked together. As a result, the Eastern Cape is home to many anti-apartheid leaders such as Robert Sobukwe, Oliver Tambo, Nelson Mandel ...
