Cyrtanthus Macmasteri Discovery Cyrtanthus macmasteri The Eastern cape is particularly rich in Amaryllidaceae, especially Cyrtanthu5 and Nerine, and is sometimes referred to as the 'headquarters' of these two genera. This is the story of the discovery of yet another species of Cyrtanthu5. by Cameron McMaster ABOVE LEFT: Cyrtanthus macmasteri, with its large My first encounter with Cyrtanthus was on our family farm in the Cathcart dis­ flared flowers, was certainly different to any other trict when 1 was a child.

So it was that on a hike through the spectacular Bolo River Gorge with my broth­ er, Nigel and his family in January 1994, when my nephew Alistair McMaster pointed out a bright red flower on a rock ledge a few metres above the river-bed, I was able to say to him, 'I think we have found a species that has not yet been described.' With its large flared flowers it was certainly different to any Cyrtanthus I had ever encountered, and its habitat and flowering time set it apart. It remind­ ed me of C. sanguineus, but its flowers were smaller and did not flare as much. I was very excited and carefully photographed it and took the flower for pressing and identification. Despite intensive searching we found no other specimens that day. 20 March 2004 Veld&Flora We sent the single specimen to nine years during which time I made ing to Fanie and Alta van Wyk, who Amaryllidaceae specialist, Dr Dee repeated trips to the Bolo River Gorge have laid out one of the most spectacu­ Snijman at the Compton Herbarium at and many similar habitats, gradually lar hiking trails in the region.

  • Newsletter No. 4 Autumn 2005
    The Southern African Bulb Group Newsletter No. 4 Autumn 2005 The Southern African Bulb Group was initiated by a group of enthusiasts on April 4th 2004. The objective of the group is to further the understanding of the cultivation of Southern African bulbs, where `bulbs' is used in the broad sense to encompass bulb-, corm- and tuber- possessing Southern African plants, including `dicots' such as Oxalis. In the first instance the group will be run on an informal basis, with an initial subscription of £5 invited from participants. Committee: Robin Attrill (Membership secretary and Newsletter editor), Margaret Corina (Treasurer), Stefan Rau and Terry Smale Editorial This issue of the newsletter contains a report of the meeting of the group held at Rupert Bowlby's Nursery on April 9th 2005, an article on Crinum moorei by David Corina, information on recent literature of interest to growers of Southern African bulbs, and an updated list of suppliers of seed and bulbs/corms of Southern African geophytes. In addition a balance sheet covering the first year of operation of the group is attached. With respect to the supplier list, please let me know if you are aware of other sources which should be included. As I have previously stated the group welcomes articles, and suggestions, for inclusion in future newsletters. Contributions (hand/typewritten and electronic are acceptable!) are urgently required and should be sent to the newsletter editor at 17 Waterhouse Moor, Harlow, Essex, CM18 6BA (Email [email protected] ) Publication of the next issue is scheduled for December 2005. Report on visit to Rupert Bowlby - Saturday 9 th April 2005 by David Corina About 20 members attended the event, and the Group would like to thank Rupert for his hospitality at the event and for opening his collection to the public gaze.

Once known as the main compound of San arrow poisons, its psychoactive properties have been recognized by Western scholars only in the last 50 years, since its ritual use was strictly kept secret by its initiates. Through the analysis of the few ancient and modern ethnographic observations that have been able to bypass the wall of secrecy that envelop the use of this plant, the Sotho male initiation rite (lebollô la banna) and the use of the plant as divinatory “bioscope ” among the South African sangoma (healers) are described. As evidenced by archaeological findings, man’s relationship with this plant has lasted for at least 2000 years. The plant The plant of leshoma is botanically classified as Boophone disticha (L. f.) Herb., belonging to the Amaryllidaceae family 1. It is a bulbaceous plant, with the bulb partially protruding from the ground. Each year the leafless bulb produces a beautiful fan of leaves which often are wavy in their margins at maturity. Once the vegetative stage is over, the plant loses its leaves, and the flowering stage begin.

    International Journal of Environmental Research and Public Health Review African Herbal Medicines: Adverse Effects and Cytotoxic Potentials with Different Therapeutic Applications Kunle Okaiyeto and Oluwafemi O. Oguntibeju * Phytomedicine and Phytochemistry Group, Oxidative Stress Research Centre, Department of Biomedical Sciences, Faculty of Health and Wellness Sciences, Cape Peninsula University of Technology, Bellville 7535, South Africa; [email protected] * Correspondence: [email protected] Abstract: The African continent is naturally endowed with various plant species with nutritional and medicinal benefits. About 80% of the people in developing countries rely on folk medicines to treat different diseases because of indigenous knowledge, availability, and cost-effectiveness. Extensive research studies have been conducted on the medicinal uses of African plants, however, the therapeutic potentials of some of these plants has remained unexploited. Over the years, several studies have revealed that some of these African floras are promising candidates for the development of novel drugs. Despite the plethora of studies on medicinal plant research in Africa, there is still little scientific data supporting the folkloric claims of these plants. Besides, safety in the use of folk medicines has been a major public health concern over the year. Therefore, it has become mandatory that relevant authority should take measures in safeguarding the populace on the use of herbal mixtures. Thus, the present review extracted relevant information from different scientific databases and highlighted some problems associated with folk medicines, adverse effects on reproductive systems, issue about safety due to the toxicity of some plants and their toxicity effects with potential Citation: Okaiyeto, K.; Oguntibeju, therapeutic benefits are discussed.

Orchidaceae (26,460 species) dwarfs all other Asparagoid families and makes the order the far most speciose of all monocot orders. Amaryllidaceae (Christenhusz et al. 2017) is largely warm-temperate and tropical in distribution with representatives on all the habitable continents.

Asparagaceae (3,220 species) and Iridaceae (2,244 species), followed by Asphodelaceae (1,200 species). All other families are considerably smaller (Christenhusz et al. 2017). Three subfamilies are recognised in Amaryllidaceae: Amaryllideae (c. 1,000 species), Allioideae (1,134 species) and Agapanthoideae (7 species). A major radiation of Amaryllideae has occurred in southern Africa, with c. 250 species (11.6% of global total of Amaryllideae). The greatest radiation of Amaryllidaceae is in the Neotropics with 375 species (17.5% of global total) with a lesser centre of distribution in the Mediterranean basin.

H. albiflos is a widespread evergreen plant, while H. pumilio is an endangered narrow endemic species with only two known populations remaining. These populations, remnants of the one recently transferred from Wellington to the Stellenbosch University Botanical gardens and another in the Duthie Reserve in Stellenbosch, present with vastly different morphologies. It is therefore vital to understand the phylogenetics and population genetics of H. pumilio as well as to design a method of in vitro propagation to increase the numbers of these plants. This study analysed the phylogenetics of H. pumilio using non-coding nuclear (Internal transcribed spacer), plastid (trnL-trnF intergenic spacer) and mitochondrial (nadi1477) gene regions and the population genetics using inter-simple sequence repeats (ISSR) and start codon targeted (SCoT) polymorphisms.
