Southern Africa has a rich legume flora comprising 133 indigenous genera and 1620 indigenous species, of which 1059 species (65%) are endemic to the flora of southern Africa region. An additional 128 non-indigenous species have become naturalised, of which 59 are invasive, resulting in 1748 species from 165 genera. There are 22 (17%) endemic genera, one endemic tribe (Hypocalyptieae) and one near-endemic tribe (Podalyrieae, with 122 of the 123 species endemic). The diversity of uses (given as total/indigenous spp.) include food and beverages (127/115 spp.), medicine (338/291 spp.), magic and charms (113/104 spp.), timber (59/55 spp.), firewood (43/31 spp.) and 10 more minor use categories. Regression analyses showed that the levels of endemism in subfamilies and tribes are directly related to the numbers of species but that the number of useful species is not related to species numbers, except for the non-papilionoid subfamilies (all uses) and non-genistoid papilionoids (medicinal uses only). The Phaseoleae and Millettieae showed high residual values in several analyses, indicating that they have been favoured in the selection of useful plants. Diversity in habit and chemistry seems to explain at least partly the use patterns.

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.

Strength properties’ tests are conducted in the small clear sample. This paper aim to acquire the basic and grade stresses of some fast growing species thus identifies its strength group. Thus, the information of wood properties from different species and condition are acquired from strength property's test. The required information namely, bending parallel to the grain, compression stress parallel to grain, shear parallel to grain and modulus of elasticity. The condition of the trees which is referred to green and air-dry condition. Three different species which are referred to exotic species of Acacia mangium and indigenous species of Aras. The results from the study indicated that, Acacia mangium classified under the strength group SG5, whilst Aras was classified under the strength group SG7. The timber is of medium density Light Hardwood ranging from 0.37-0.52g/cm3 air-dry condition.

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.

It is stated that there is a need both to extend the range of barrier plants available in South Africa, and to replace some much-used exotic species that have become invasive. A literature survey and computerized herbarium search revealed that of the 428 plants recorded as having been used as barriers 62% are exotics. Of these. 26% are naturalized or invasive in one or other part of South Africa. Ideal characteristics for different types of barrier plants have been defined and used as a guide in selecting a range of potential barrier plants from the indigenous species available. Lists of recognized barrier plants are given including some species revealed as a result of the present investigation.
