Abstract In the Flora of southern Africa area, comprising the countries of South Africa, Namibia, Botswana, Lesotho and Swaziland, the moss family Sematophyllaceae consists of three genera (Trichosteleum, Donnellia and Sematophyllum) and nine species. Core sematophyllous taxa with collenchymatous exothecial cells, long rostrate operculum, linear leaf cells and differentiated alar cells are included in the family. Meiothecium fuscescens is transferred to Donnellia and a new combination made. Sematophyllum wageri is reduced to synonymy under S. brachycarpum and a lectotype is designated for S. dregei. Each species is described and its distribution mapped.

In the genus Solanum L. (Solanaceae), subgenus Leptostemonum (Dunal) Bitter, section Acanthophora Dunal has four representatives in the Flora of southern Africa region (South Africa. Lesotho, Swaziland, Namibia. Botswana), namely  S. aculeatissimum Jacq.. S. capsicoides Allioni. S. mammosum L. (cultivated only) and S. viarum Dunal. Section  Ton a Nees has two representatives in southern Africa, namely S.  chnsotriclium Schltdl.

All are introduced species native to the New World. Descriptions, discussions, illustrations and distribution maps of the naturalized species are presented, as well as keys to the species of both sections.

A New Species

A new species of the southern Africa endemic genus Eliokarmos, that includes the well-known chincherinchees, is described from the vicinity of Kotzesrus, Northern Cape Province of South Africa. Eliokarmos humanii sp. nov. is unique in the genus based on its single, slightly fleshy, suborbicular, convex leaf with ciliate margin, and the short subspiciform inflorescence with almost sessile flowers. A complete description is presented for this species, and data on morphology, ecology, and distribution are reported. In addition, Ornithogalum richtersveldensis, recently described from northwestern South Africa, is transferred to Eliokarmos based on its morphology and biogeography, and a new combination is presented for this species in the latter genus.

Flora Of Southern Africa

Background: The grasses (Poaceae) of the Flora of Southern Africa (FSA) region (i.e. Botswana, Eswatini, Lesotho, Namibia and South Africa) are relatively well documented, for both native and non-native species. Visiting taxonomic expertise nevertheless reveals new FSA and in-country records, particularly of non-native species. Such records provide an opportunity for improving biosecurity relating to potentially invasive but hitherto undetected non-native Poaceae in the FSA region.Objectives: To improve floristic data for non-native Poaceae occurring in theFSA region.Method: Field collections were made, herbarium collections, databases and relevant literature were studied.Results: New records are presented for non-native grasses that were encountered as locally common populations in the Drakensberg Mountain Centre of Floristic Endemism (DMC, Lesotho and South Africa). Festuca rubra and Agrostis capillaris are newly reported for sub-Saharan Africa and southern Africa and are also the first verified specimens reported for the African continent, with previous reports from northern-most Africa (Morocco, Algeria and/or Tunisia) uncertain. Jarava plumosa, introduced from South America and previously known for the whole of Africa from a single population in the Western Cape, South Africa, is newly reported from the border between the Eastern Cape, South Africa and Lesotho. The ecological implications, including the potential to become invasive, are discussed for each species, with taxonomic notes given to help differentiate them from closely resembling taxa.Conclusion: These new records of alien grass species raise concerns over their potential ecological impact, particularly as they are found in an area of conservation importance. Future efforts to monitor their distribution are of importance.

The Family

The classification of the plant family Asteraceae is discussed. The family belongs to the division Spermatophyta (Magnoliophyta), subdivision Angiospermae, class Dicotyledoneae (Magnoliopsida), subclass Asteridae, superorder Asteranae and the order Asterales and is divided into three subfamilies: the Barnadesioideae (not in Flora of southern Africa region), the Cichorioideae and the Asteriodeae. The subfamily Cichorioideae is further divided into eight tribes of which one (Liabeae) does not occur in southern Africa and one genus (Corymbium) is not assigned to a tribe. The subfamily Asteriodeae is divided into 10 tribes. The subfamily Cichorioideae and its tribes are more fully described in this article. The genera belonging to these tribes are listed and their distribution given.

Bottomley’s (1948) Gasteromycetes of South Africa is still widely used for identification purposes. However, as a result of developments since 1948, the work has become outdated in many respects. Entries in the Clathraceae are here updated and briefly commented upon and a species key to the twelve southern African representatives of the family is provided.

Family murders in South Africa The goal of research into ‘Family Murders in South Africa’ was to determine the views of members of the Criminological Society of Southern Africa concerning family murder. The hypothesis was that these informed persons would agree with the statements made by academics in the press regarding this phenomenon. The research substantiated the hypothesis. The dominant psychological causes were listed as feelings of rejection, stress, emotional burn-out and pathological possessiveness. The sociological causes were listed as alienation between spouses and misuse of alcohol. The warning signs included previous suicide attempts, unsuccessful attempts to restore broken marriages, unemployment, physical assault, fathers retreating from the family and neighbours and obsessive handling of dangerous weapons. Based on the findings of the research, a list identifying causes, warning signs, explanations, and methods of prevention was drawn up.

The knowledge of the Hydraenidae of sub-Saharan Africa, and in particular of the genus Hydraena Kugelann, 1794, is most incomplete. As an example, in southern Africa only three species were described before the revision of Perkins (2014), which raised the number to 31. Only 15 species are currently known from Central Africa, between the Sahel and South Africa, all belonging to subgenus Hydraenopsis Janssens, 1972 (Trizzino et al. 2013), but many more remain to be described and discovered. The islands of the Gulf of Guinea are no exception to this lack of knowledge (Jones 1994), and only one species of the family was previously known, H. (Hydraenopsis) pagaluensis Hernando & Ribera, 2001 from Annobón (Hernando & Ribera 2001; Trizzino et al. 2013). In this paper we describe the first known species of Hydraenidae from Bioko, the largest and closest to the continent of these islands. The species were collected by our friend and colleague Vasily Grebennikov during a survey of the forest litter fauna of Annobón and Bioko. Despite considerable efforts no Hydraenidae were found in Annobón, and only these two species, in a single locality, in Bioko.
