The eastern Cape is a region of variable environmental factors, with a flora estimated at about 3 600 -4 000 species and encompassing 21 of Acocks’s (1975) veld types. It lies at the edges of the major phytochoria present in southern Africa, with many tropical species reaching the southern and western limits o f their distribution, and many south-western Cape and Karoo species reaching the northern and eastern limits of their distribution. The apparently low incidence o f species endemic to the eastern Cape may be the result of selection for ‘generalist’ genotypes and the close proximity of different phytochoria, which may allow species to migrate between phytochoria to fill niches resulting from environmental change.

History Of

The histories of the two swine fevers in southern Africa differ widely. Classical swine fever (hog cholera) has been known in the northern hemisphere since 1830 and it is probable that early cases of ‘swine fever’ in European settlers’ pigs in southern Africa were accepted to be that disease. It was only in 1921 that the first description of African swine fever as an entity different from classical swine fever was published after the disease had been studied in settlers’ pigs in Kenya. Shortly after that, reports of African swine fever in settlers’ pigs emerged from South Africa and Angola. In South Africa, the report related to pigs in the north-eastern part of the country. Previously (in 1905 or earlier) a disease assumed to be classical swine fever caused high mortality among pigs in the Western Cape and was only eradicated in 1918. African swine fever was found over the following years to be endemic in most southern African countries. Classical swine fever, however, apart from an introduction with subsequent endemic establishment in Madagascar and a number of introductions into Mauritius, the last one in 2000, had apparently remained absent from the region until it was diagnosed in the Western and subsequently the Eastern Cape of South Africa in 2005. It was eradicated by 2007. The history of these diseases in the southern African region demonstrates their importance and their potential for spread over long distances, emphasising the need for improved management of both diseases wherever they occur.

Induce Abortion

This was a descriptive study aimed at exploring the personal experiences of women who induce abortion and the circumstances surrounding induced abortion. The study was conducted in six public hospitals in four different provinces: Baragwanath (Gauteng), Groote Schuur and Tygerberg (Western Cape), King Edward and R.K. Khan (Kwa-Zulu/Natal) and Livingstone (Eastern Cape). In-depth interviews were conducted with 25 African, Indian and Coloured women admitted to the hospitals following backstreet abortions. The study gave women the opportunity to "speak for themselves" about "why" and "how" and the context in which the unscfe induced abortions occurred

A population of Xiphinema bolandium from the Baviaanskloof Wilderness Area in the Eastern Cape Province was studied, and the four juvenile stages described and figured for the first time. New distribution records are listed from several localities in the Western Cape Province, mostly from vineyards and peach orchards, as well as from fynbos.

Breutelia microdonta (Mitt.) Broth., described originally from Brazil, is the oldest name for a disjunct widespread tropical species that includes as synonyms B. angustifolia Rehm. ex Sim of Southern Africa and B. merrillii Broth. of the Philippines. Breutelia kilaueae (C. Muell.) Broth. of Hawaii is considered a synonym of the austral Pacific species B. affinis (Hook.) Mitt., and B. brachyphylla Broth. of Ecuador is reduced to synonymy under the North Andean B. squarrosa Jaeg. Breutelia anacolioides Herz. of Bolivia is removed to Philonotis as a synonym of the North Andean P. incana (Tayl.) H. Robins. Differences in spore ornamentation offer an additional character distinguishing Breutelia from Philonotis.

Gang violence has been extensively highlighted as an issue of national concern in South Africa. Gangs also pose concerns about the social contexts of the communities in which they are found. The Western Cape and Eastern Cape provinces have had the most prolific occurrences of gangsterism. Here gangs have demonstrated unique characteristics that set them apart from gangs in other areas. This article examines the context of gangsterism in the selected provinces by means of a comparative analysis. The purpose is to provide some strategies for effective intervention. The discussion also interrogates how or why intervention efforts may have failed and what could be improved in order to strengthen the chances of success of future interventions in affected communities.

Abstract Sediments are the most important source of Late Quaternary palaeoclimate information in southern Africa, but have been little studied from a geochemical perspective. However, recent advances in analytical techniques that allow rapid and near-continuous elemental records to be obtained from sedimentary sequences has resulted in the increasing use of elemental indicators for reconstructing climate. This paper explores the diverse information that can be acquired from the inorganic component of sediments and reviews some of the progress that has been made over the last two decades in interpreting the climatic history of southern Africa using elemental records. Despite the general scarcity of elemental records, excellent examples from the region exist, which provide some of the longest and most highly resolved sequences of environmental change currently available. Records from Tswaing crater and marine deposits on the southern KwaZulu-Natal coastline have provided rare glimpses into hydroclimate variability over the last 200 000 years, suggesting that summer rainfall in the region responded predominantly to insolation forcing on glacial-interglacial timescales. Over shorter timescales, lakes and wetlands found in the Wilderness embayment on the southern Cape coast and along the Maputaland coast in north-eastern South Africa have yielded highly-resolved elemental records of Holocene environmental change, providing insight into the changing interactions between tropical (e.g., El Niño-Southern Oscillation) and temperate (e.g., mid-latitude westerlies) climate systems affecting rainfall variability in the region. The examples discussed demonstrate the multiple environmental processes that can be inferred from elemental proxies and the unique insight this can provide in advancing our understanding of past climate change on different timescales. The interpretation of geochemical data can be complicated by the complex nature of sedimentary environments, various proxy assumptions and analytical challenges, and the reliability of sediment-based climate reconstructions is substantially enhanced through multi-proxy approaches.

Typical Variety

Fossombronia capensis S.W.Amell var. spiralis Perold, var. nov. from Western Cape is described. It is distinguished from the typical variety by a suite of characters, the most obvious being the strong spirals in the elaters. In  F. capensis var. capensis the spirals are weak except for two Arnell collections in which they are quite strong. Subtle differences in spore ornamentation are then, perhaps, the most definitive character to separate the two varieties.
