    Available online at www.sciencedirect.com South African Journal of Botany 75 (2009) 185–195 www.elsevier.com/locate/sajb Review Artemisia afra: A potential flagship for African medicinal plants? ⁎ N.Q. Liu, F. Van der Kooy , R. Verpoorte Division of Pharmacognosy, Section of Metabolomics, Institute of Biology, Leiden University, PO Box 9502, 2300RA Leiden, The Netherlands Received 11 July 2008; received in revised form 4 November 2008; accepted 6 November 2008 Abstract The genus Artemisia consists of about 500 species, occurring throughout the world. Some very important drug leads have been discovered from this genus, notably artemisinin, the well known anti-malarial drug isolated from the Chinese herb Artemisia annua. The genus is also known for its aromatic nature and hence research has been focussed on the chemical compositions of the volatile secondary metabolites obtained from various Artemisia species. In the southern African region, A. afra is one of the most popular and commonly used herbal medicines. It is used to treat various ailments ranging from coughs and colds to malaria and diabetes. Although it is one of the most popular local herbal medicines, only limited scientific research, mainly focussing on the volatile secondary metabolites content, has been conducted on this species. The aim of this review was therefore to collect all available scientific literature published on A. afra and combine it into this paper. In this review, a general overview will be given on the morphology, taxonomy and geographical distribution of A. afra. The major focus will however be on the secondary metabolites, mainly the volatile secondary metabolites, which have been identified from this species.

Suggested reference to maps and this report: Vlok, J.H.J., Cowling, R.M. & Wolf, T., 2005. A vegetation map for the Little Karoo. Unpublished maps and report for a SKEP project supported by CEPF grant no 1064410304. EXECUTIVE SUMMARY: Stakeholders in the southern karoo region of the SKEP project identified the need for a more detailed vegetation map of the Little Karoo region. CEPF funded the project team to map the vegetation of the Little Karoo region (ca. 20 000 km ²) at a scale of 1:50 000. The main outputs required were to classify, map and describe the vegetation in such a way that end-users could use the digital maps at four different tiers. Results of this study were also to be presented to stakeholders in the region to solicit their opinion about the dissemination of the products of this project and to suggest how this project should be developed further. In this document we explain how a six-tier vegetation classification system was developed, tested and improved in the field and the vegetation was mapped. Some A3-sized examples of the vegetation maps are provided, with the full datasets available in digital (ARCVIEW) format. A total of 56 habitat types, that comprises 369 vegetation units, were identified and mapped in the Little Karoo region.

  • A Taxonomic Revision of the Pteronia Camphorate Group (Astereae, Asteraceae)

    A Taxonomic Revision of the Pteronia Camphorate Group (Astereae, Asteraceae)

    Bello, A.O. et al. (2017). A taxonomic revision of the Pteronia camphorate group (Astereae, Asteraceae). South African Journal of Botany, 113: 277-278 https://dx.doi.org/10.1016/j.sajb.2017.08.017 A taxonomic revision of the Pteronia camphorate group (Astereae, Asteraceae) A.O. Bello, J.S. Boatwright, P.M. Tilney, M. Van der Bank and A.R.Magee Abstract: As a first step towards a comprehensive revision of Pteronia (Asteraceae, Astereae), we present here a taxonomic treatment of the Pteronia camphorata group, in which we recognise three species. The group includes the type spe- cies P. camphorata (an important medicinal plant) and is easily distinguished from the rest of the genus by the gla- brous rather than glandular or variously pilose cypselas. The lectotype of P. camphorata has involucral bracts with entire margins and long acuminate apices, both diagnostic characters for P. stricta. As such P. stricta is here reduced into synonymy with P. camphorata and the next available name, P. aspera Thunb, reinstated to accommodate the species heretofore treated as P. camphorata. Three varieties within Pteronia camphorata had been previously recognised (var. armata, var. laevigata and var. longifolia). The characters distinguishing var. armata were found to be continuous with the variation observed within var. longifolia. The third infraspecific taxon, var. laevigata, was however found to be distinct and is therefore recognised here as a new species, P. cederbergensis Bello, Magee & Boatwr. It is readily distinguished by the glabrous branches, opposite to sub-opposite somewhat succulent leaves, the 2-seriate pappus and larger, obclavate cypselas. Transverse sections of the leaves and cypselas were also examined and provide additional differences between the three recognised species.
