Question: Which is a species in southern Africa, Clytostoma or Zantedeschia aethiopica?
Context: Who's Who of Southern Africa is the name of an annual print publication distributed in Southern Africa, containing biographical information about prominent professionals in the Southern African region.  According to the website, Southern Africa consists of South Africa, Namibia, Botswana, Zimbabwe, Lesotho, Swaziland and Mozambique.  The book has been a source of information regarding noteworthy people in Southern Africa for over 100 years. Pseudolachnostylis is a genus of plants in the Phyllanthaceae first described as a genus in 1899.  It contains only one known species, Pseudolachnostylis maprouneifolia native to central and southern Africa.  Its common name is kudu berry, though the term also applies for "Cassine aethiopica". The red-billed quelea ("Quelea quelea"), also known as the red-billed weaver or red-billed dioch, is a small—approximately 12 cm long and weighing 15-26 g —migratory, sparrow-like bird of the weaver family, Ploceidae, native to Sub-Saharan Africa.  It was named by Linnaeus in 1758, who considered it a bunting, but Ludwig Reichenbach assigned it in 1850 to the new genus "Quelea".  Three subspecies are recognised, with "Quelea quelea quelea" occurring roughly from Senegal to Chad, "Q. q. aethiopica" from Sudan to Somalia and Tanzania, and "Q. q. lathamii" from Gabon to Mozambique and South Africa.  Non-breeding birds have light underparts, striped brown upper parts, yellow-edged flight feathers and a reddish bill.  Breeding females attain a yellowish bill.  Breeding males have a black (or rarely white) facial mask, surrounded by a purplish, pinkish, rusty or yellowish wash on the head and breast.  The species avoids forests, deserts and colder areas such as those at high altitude and in southern South Africa.  It constructs oval roofed nests woven from strips of grass hanging from thorny branches, sugar cane or reeds.  It breeds in very large colonies. The genera of plants within the tribe Stapeliae are all to varying degrees stem succulents.  Many of the species resemble cacti, though are not closely related, as an example of convergent evolution.  The stems are often angular, mostly four-angled in cross-section, but in some species there are six or more, with some species of "Hoodia" having more than thirty angles.  In size they vary from less than 2.5 cm/1" in length to over 2 m/6" tall.  The leaves are in most species reduced to rudiments, sometimes hardened and thorn-like, arranged on bumps or tubercles on the angles.  Some species, however, still have recognisable leaves, most notably the Indian species "Frerea indica", and some members of "Tridentea".  Stapeliads are most abundant in warm, dry climates.  In Africa, there are two separate regions where Stapeliads have most diversified: northeast Africa, and Southern Africa.  Several species are endemic to the small island of Socotra off the Horn of Africa.  The Arabian Peninsula, and most specifically the country of Yemen, contain another concentration of species.  Several more are found in the drier parts of Pakistan, Afghanistan, India, Nepal, and Myanmar.  A single species, "Caralluma europea" is found in Europe, in the very southern part of the Iberian peninsula.  Stapeliads are often regarded as a climax group within the family because of their often structurally complex flowers. Certain aspects of these reproductive parts mirror the pollination systems in the Orchid family and represent a case of parallel evolution though both groups are quite unrelated and have developed similar, though not identical means to achieve the ultimate goal of pollination and therefore reproduction.  Most stapeliads use flies as pollinators, that are attracted to odours resembling dung or rotting meat, emanating from the flowers.  Many of the flowers also bear some physical resemblance to rotting animal carcasses, leading to their popular name of Carrion Flowers.  However, not all stapeliads smell bad, or attract flies.  Some species use beetles, bees, wasps, butterflies or moths as pollinators.  Stapeliad flowers range in size from mere millimetres in species of "Echidnopsis" and "Pseudolithos" to those of "Stapelia gigantea" that can reach 40 cm/16" in diameter, and are some the largest of flowers to be found on any species of succulent. Thomas N. Huffman (born 17 July 1944) is Professor Emeritus of archaeology in association with the University of Witwatersrand in Johannesburg, South Africa.  He specialises in pre-colonial farming societies in southern Africa.  Huffman is most well known for his identification of the Central Cattle Pattern at Mapungubwe, a pre-colonial state in southern Africa.  This, in turn he argued as the main influence in the formation of the Zimbabwe Pattern at Great Zimbabwe.  Arguably his seminal contribution to the field was "A Handbook to the Iron Age: The Archaeology of Pre-Colonial Farming Societies in Southern Africa" (2007), which has contributed to the understanding of ceramic style analysis and culture history focusing on these groups. Clytostoma was a genus of woody-stemmed vines from tropical America, native to Argentina and the southern part of Brazil.  It is now considered a synonym of "Bignonia".  The botanical name comes from the Greek, "klytos" means splendid or beauteous, and "stoma" means mouth; alluding to the beautiful flowers.  It is closely related to "Bignonia", from which it differs chiefly in its simple slender tendrils, the short disk, and that it has a habit of clambering over adjacent foliage using tendrils to hang on tight.  The bright glossy green leaves are lobed and divided with 2 leaflets, about 3in (7.6cm) long and 1.5in (3.8cm) wide.  They are arranged opposite in pairs and tendrils arise at the ends of the leaf stalks.  In late spring, the spectacular 1.5in (3.8cm) trumpet flowers are borne terminally or along the branches.  The flowers are pale lavender and delicately detailed with dark violet and purple veins.  Flowers are followed by large prickly seed pods.  This evergreen ornamental plant easily reaches to 16 feet and is a carefree grower.  It has only recently been moved out of the genus "Pandorea". This is a list of the bird species recorded in Southern Africa.  Southern Africa is defined as Africa south of a line between the Kunene and Zambezi rivers, encompassing Namibia, Botswana, Zimbabwe, mainland South Africa, Lesotho, Swaziland and southern and central Mozambique, as well as oceanic waters within 200 nmi of the coast, covering approximately 3.5 million square kilometres. Zantedeschia aethiopica (known as calla lily and arum lily) is a species in the family Araceae, native to southern Africa in Lesotho, South Africa, and Swaziland. Zantedeschia is a genus of 8 species of herbaceous, perennial, flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi.  The genus has been introduced on all continents except Antarctica.  Common names include arum lily for "Z. aethiopica" and calla and calla lily for "Z. elliottiana" and "Z. rehmannii", although members of the genus are neither true lilies of Liliaceae, true "Arums", or true "Callas" (related genera in Araceae).  They are also often confused with "Anthurium".  The colourful flowers and leaves of both species and cultivars are greatly valued and commonly grown as ornamental plants. The Southern African Special Administrative Region is a political concept proposing the creation of an autonomous self-governing region – or special administrative region (SAR) – in southern Africa.  The proposal, made to encourage political discourse, was put forward in late 2007 following popular concern that southern Africa was at risk of losing political, social and economic headway.  Much of the discussion to date has surrounded the need for the nucleation of an economic and social example for southern Africa, as well as innovative approaches to reducing crime and poverty in the region.
