Question: Among Bursera and Berkheya, which can be found in South Africa?
Context: 1961 Ireland rugby union tour of South Africa.  Between 1906 and 1960 South Africa had played Ireland on five occasions.  However all of these games had been played in Ireland.  In 1960 South Africa had beaten Ireland 8–3 at Lansdowne Road.  The following year Ireland embarked on their first tour of South Africa.  Among the touring party was Tony O'Reilly who had previously toured South Africa with the British Lions in 1955.  The tour began with a full international at Newlands Stadium which Ireland lost 24–8.  Tom Kiernan scored all of Ireland's points with a try, a conversion and a penalty.  Four members of this touring party – Niall Brophy, Tom Kiernan, Syd Millar and Bill Mulcahy – would return to South Africa with the British Lions in 1962.  Kiernan, Millar and Ronnie Dawson, as a coach, would also return with the Lions in 1968. List of Mountains in South Africa is a general list of mountains in South Africa, with elevation.  This list includes mountains in two other sovereign states, in the Stormberg-Drakensberg range, where the highest elevations are to be found in Lesotho, as well as Emlembe, the highest mountain in Swaziland, located at the border with South Africa.  The highest mountain in South Africa is 3450 m high Mafadi, located on the border of South Africa and Lesotho. Boom Shaka was a pioneering kwaito music group from South Africa, consisting of Junior Sokhela, Lebo Mathosa, Theo Nhlengethwa and Thembi Seete.  Their first album was produced in 1994.  Boom Shaka's first single "It's About Time" was released in 1993.  This track (and others by Boom Shaka) can be found on Stern's Music website (http://www.sternsmusic.com/discography_detailed/665).  Boom Shaka became one of the most successful bands of the mid-1990s in South Africa and their music became the soundtrack for many young people in the newly democratic South Africa.  Boom Shaka was able to break into the international market and achieved success outside of South Africa in London among other places. The private security industry in South Africa is an industry providing guarding, monitoring, armed reaction, escorting, investigating and other security-related services to private individuals and companies in the country.  Over the years there has been tremendous growth in the private security industry, not only in South Africa, but also in the rest of the world.  The private security industry in South Africa is among the largest in the world, with over 9,000 registered companies, 450,000 registered active private security guards and a further 1.5 million qualified (but inactive) guards; many times the available personnel than the combined South African police and army.  Studies have shown that South Africa had 2.57 private security personnel for every police employee.  This is attributed by some to the country's relatively high levels of crime to a lack of public funds from Parliament towards the South African Police Service (SAPS) or to an increasing trend in many countries towards government outsourcing of certain security functions.  Others have suggested the number of high-wealth individuals in South Africa in comparison with the rest of Africa has led to the growth of the industry. The Swazi are considered part of theNguni-speaking people in southeastern Africa who migrated from North East Africa and are found in Swaziland and others in South Africa where the Eastern region of Mpumalanga in South Africa was part of Swaziland until it was occupied by the Boer settlers in the 1800s.  The Swati are part of the Nguni family that can be archaeologically traced in East Africa where the same tradition,beliefs and cultural practices are found.  The Swati share a unique experience,culture and Royal lineage.  This lineage is exclusive to the inhabitants of Swaziland even though there have been more Swazi people that have moved to South Africa and the United Kingdom in the 20th century.  The original inhabitants of Swaziland no longer reside in Swaziland as a majority population while some remain in the land.  The Swazi people and the Kingdom of Swaziland today are named after Mswati II, who became king in 1839 after the death of his father King Sobhuza who strategically deafeated the British who occupied Swaziland.  The Kingdom of Swaziland was a region occupied by the San people of Southern Africa and the current Swazis came in from North Eastern regions through to Mozambique and eventually Swaziland in the 15th century.  Mixtures with the San people and other Nguni tribes occurred.  Their royal lineage can be traced to a chief named Dlamini I; this is still the royal clan name.  About three-quarters of the clan groups are Nguni; the remainder are Sotho , Tsonga, others North East African and San descendants.  These groups have intermarried freely.  There are slight differences among Swazis as a nation with varying features and skin tones yet Swazi identity extends to all those with allegiance to the twin monarchs Ingwenyama "the Lion" (the king) and Indlovukati "the She-Elephant" (the queen mother).  The dominant Swati language and culture are factors that unify Swazis as a nation since there is no other language spoken except for English.  This makes the Swati nation a peaceful and prideful group of people that have never experienced any violence, wars and major conflicts.  It remains as the last absolute monarchy in Africa and is known for its beautiful well manicured lush mountains,beautiful culture and natural scenery. Bursera, named after the Danish botanist Joachim Burser (1583-1639), is a genus with about 100 described species of flowering shrubs and trees varying in size up to 25 m high.  They are native (often for many species endemic) to the Americas, from the southern United States south through to northern Argentina, in tropical and warm temperate forest habitats. Swazi Music Radio (SMR) was a South African radio station broadcasting from Swaziland between 1972 and 1978.  It was initially established as Swaziland Commercial Radio but was soon taken over by the South African entrepreneurs Issie and Natie Kirsh as a competitor to LM Radio which broadcast from nearby Mozambique.  The studios were based in central Johannesburg and the transmitters were in Sandlane in Swaziland, just across the eastern border of South Africa, not far from the small town of Amsterdam.  Programmes were recorded in Johannesburg and the tapes taken by road to the transmitting station for broadcast the next day.  It had been hoped that the medium wave transmission would reach the Johannesburg area during the day, however long distance medium wave propagation in the former Transvaal Province was poor and only really effective at night.  Daytime listening was on short wave.  During the years it operated, SMR recruited many of the announcers who had been on LM Radio and SABC stations, among them Gary Edwards, Frank Sanders, John Berks, Darryl Jooste, Leon Fourie, Barry O'Dee and Gordon Hoffman.  Another former LM radio announcer George Wayne also returned briefly from Australia to join the station.  (Stan Katz, who later went on to become one of South Africa's most prominent broadcasters, joined the station in its early days as a junior programming assistant).  Overall, SMR was not commercially successful as it could not compete with the superior technical transmission of Radio 5 (now 5FM) which took over from LM Radio when that station closed in October 1975 and relocated from Mozambique to South Africa.  Operated by the South African Broadcasting Corporation, Radio 5 was heard via local medium wave transmitters in all the major cities in South Africa and also had good short wave coverage.  When SMR eventually closed, the studios and transmitters were used to broadcast three ethnic radio services - Radio SR, targeted to the black African market, Radio Paralello 27 which broadcast in Portuguese and Radio Truro aimed at the Indian population of South Africa under the direction of radio veterans Rob Vickers and Zena Watkins.  These stations all closed down in the 1980s. Berkheya is a genus of flowering plants in the aster family, Asteraceae, and the subfamily Carduoideae, the thistles.  It is distributed in tropical Africa, especially in southern regions.  Of about 75 species, 71 can be found in South Africa. Peter Richard Dreyer (born November 15, 1939) is the author of "A Beast in View" (London: André Deutsch), "The Future of Treason" (New York: Ballantine), "A Gardener Touched with Genius: The Life of Luther Burbank" (New York: Coward, McCann & Geoghegan; rev. ed., Berkeley: University of California Press; new, expanded ed., Santa Rosa, CA: Luther Burbank Home & Gardens), and "Martyrs and Fanatics: South Africa and Human Destiny" (New York: Simon & Schuster; London: Secker & Warburg).  He was born and brought up in South Africa, where he was involved in the anti-apartheid struggle, serving on the Cape Provincial Committee of the Liberal Party, founded and led by Alan Paton, and as secretary of the Western Province Press Association, which published the fortnightly "The Citizen" (not to be confused with the pro-apartheid tabloid of the same name launched in 1976), which introduced the concept of nonracial democracy in South Africa.  At the time, the Liberal Party was the only unsegregated political party in South Africa.  The African National Congress (ANC) restricted its membership to black Africans (excluding not only "whites" but "Coloured" and Indian South Africans too), and did not desegregate itself until many years later.  Dreyer put forward the idea of nonracialism in a pamphlet titled "Against Racial Status and Social Segregation" (Claremont, Cape Town, 1958; now very rare, but to be found in the Bodleian Library at Oxford University and the Hoover Library at Stanford University).  The Citizen Group also worked to establish nonracial trade unions, resistance to bus apartheid in Cape Town, and a nonracial theater project, which led to a production of Jean Genet's "The Blacks".  On February 8, 1958, Patrick Duncan launched the Liberal Party fortnightly "Contact", with offices on Parliament Street in Cape Town.  Dreyer worked closely with Duncan, and in "Contact", 1, no. 15, dated August 23, 1958, he published an article about the newly formed nonracial South African Meat Workers Union under the by-line “Contact Special Correspondent.”  On the cover of the magazine, Duncan placed the Citizen group slogan “Forward to a South African patriotism based on non-racial democracy”—the first prominent demand for a nonracial answer to apartheid. The fauna of South Africa is varied, but largely typical of the ecosystems of Africa.  South Africa is ranked sixth out of the world’s seventeen megadiverse countries.  Many endemic species are unique to South Africa and are found nowhere else in the world.  South Africa is among the world leaders in conservation, though there are several significant conservation challenges which South Africa needs to resolve.
