The genus Keetia E.Phillips has a single representative in the Flora of southern Africa region (FSA). namely K.  gueinzii (Sond.) Bridson. The genus and this species are discussed, the distribution mapped and traditional uses indicated. The structures of the calycine colleters, and the ‘stylar head' complex which is involved in secondary pollen presentation, are elucidated and compared w ith existing descriptions. Intercellular, non-nodulating, slime-producing bacteria are reported in leaves of a Keetia for the first time. Differences between the southern African representativ es o f Keetia, Psydrax Gaertn. Afrocanthium (Bridson) Lantz B.Bremer, and Canthium s. str.. which for many years were included in Canthium s.I., are given.

History Of Use

The Lamiaceae is undoubtedly an important plant family, having a rich history of use that spans the globe with many species being used in folk medicine and modern industries alike. Their ability to produce aromatic volatile oils has made them valuable sources of materials in the cosmetic, culinary, and pharmaceutical industries. A thorough account of the taxonomic diversity, chemistry and ethnobotany is lacking for southern African Lamiaceae, which feature some of the region’s most notable medicinal and edible plant species. We provide a comprehensive insight into the Lamiaceae flora of southern Africa, comprising 297 species in 42 genera, 105 of which are endemic to the subcontinent. We further explore the medicinal and traditional uses, where all genera with documented uses are covered for the region. A broad review of the chemistry of southern African Lamiaceae is presented, noting that only 101 species (34%) have been investigated chemically (either their volatile oils or phytochemical characterization of secondary metabolites), thus presenting many and varied opportunities for further studies. The main aim of our study was therefore to present an up-to-date account of the botany, chemistry and traditional uses of the family in southern Africa, and to identify obvious knowledge gaps.

Abstract The article argues that “esotericism” can usefully be applied to a number of religious currents in Southern Africa. With a focus on Botswana, we survey a range of practices, from traditional “shamanic” healing to Pentecostal NRM s to New Age spiritualities and neoshamanism, some presented here for the first time. The term esotericism is useful for analysing the religious situation in Southern African contexts for three reasons. First, through a typological understanding of esotericism as initiation-based knowledge systems, we define one part of the landscape (usually termed “shamanism”) as constituting a form of “indigenous esotericism”. Second, through the European colonial expansion, this indigenous esotericism faced a violent rejection campaign that parallels the construction of “rejected knowledge” in Europe. While this forced many practices underground, they have resurfaced within Southern African Christianity. Third, “western” esoteric currents have recently been imported to Southern Africa and enter into dialogues with the “indigenous” forms.

Recently Brenan. in Kew Bull. 21 : 477-480 (1968). upheld  Acacia brevispica Harms and A. schweinfurthii Brenan Exell as distinct species and recognized two subspecies within A. brevispica. These conclusions differ from earlier results published by Ross Gordon- Gray in Brittonia 18: 44-63 (1966). Consequently it was considered necessary to re-examine these species in preparation for the account of  Acacia for the Flora of Southern Africa. Distribution maps of the two species are provided and the differences between the species tabulated and discussed. Despite certain difficulties in Natal. Brenan's taxonomic conclusions are adopted. A map showing the distribution of  A. schweinfurthii and  A. brevispica subsp. dregeana in Natal is provided and a selection of Natal specimens cited.

Family Tecophilaeaceae subfam. Tecophilaeoideae is revised for the Flora of southern Africa region, with the inclusion of the tropical Walleria mackenzii J.Kirk for completeness. The genera Cyanella Royen ex L. (9 spp.), Eremiolirion J.C.Manning F.Forest (1 sp.) and Walleria J.Kirk (3 spp.) are treated, with keys to the genera, species and subspecies; and full descriptions and distribution maps. A formal infrageneric classification is proposed for Cyanella, in which sect. Trigella (Salisb.) Pax K.Hoffm. is revived for the species with a 3 + 3 arrangement of stamens. The new species, C. marlothii J.C.Manning Goldblatt, is described from the Richtersveld; and C. pentheri Zahlbr. is resuscitated from the synonomy of C. hyacinthioides Royen ex L. Pink-flowered plants of normally yellow-flowered C. lutea have a separate geographical distribution and are recognized as subsp. rosea (Eckl. ex Baker) J.C.Manning Goldblatt.
