  • Mothers, Markets and Medicine Hanna Lindh
    Mothers, markets and medicine The role of traditional herbal medicine in primary women and child health care in the Dar es Salaam region, Tanzania Hanna Lindh Degree project in biology, Bachelor of science, 2015 Examensarbete i biologi 15 hp till kandidatexamen, 2015 Biology Education Centre, Uppsala University Supervisors: Sarina Veldman and Hugo de Boer 1 Abstract Traditional medicine is still the most common primary healthcare used in Tanzania, especially among women. The ethnobotanical studies performed in Tanzania have not explored women’s traditional medicine, with the result that we do not know that much about it, including if women’s usage of medicinal plants create a threat against the medicinal flora’s biodiversity or not. Field studies consisting of interviews and collections of medicinal plants were carried out in the Dar es Salaam region in Tanzania before identifying the collected specimens by DNA barcoding, literature and morphology in Uppsala, Sweden. The 33 informants belonged to 15 different ethnic groups and 79% of them had migrated to Dar es Salaam. A total of 249 plant species were mentioned for women’s healthcare and 140 for children’s healthcare. The medicinal plants frequently reported as used for women’s health and childcare during structured interviews and free-listing exercises were Senna occidentalis/ Cassia abbreviata, Zanthoxylum sp., Clausena anisata, Acalypha ornata and Ximenia sp. The most salient uses of medicinal plants by women were during pregnancy, childbirth, menstruation, to induce abortion, and for cleansing infants and treating convulsions in children. Most of the fresh specimens were collected from disturbance vegetation. The informants having most interview answers in common were the market vendors, healers and herbalists and they were the only informants that mentioned species listed as vulnerable on the IUCN Red List of Threatened Species.

  • Encephalartos Woodii ELSA POOLEY Writes About the Mysterious Enigma Wood’S Cycad, a Plant That Is Extinct in the Wild
    Encephalartos woodii ELSA POOLEY writes about the mysterious enigma Wood’s cycad, a plant that is extinct in the wild. Wood’s cycad is one of the most magnificent and rare plants of this family of ancient plants. It has been extinct in the wild for nearly a century. Only one four-stemmed male plant was ever found. It was first collected by John Medley Wood, director of the Natal Government Herbarium and leading Natal botanist. He was on a botanical expedition in Zululand in 1895, and found it when exploring Ngoye Forest (now spelt Ongoye). In 1903 several suckers Encephalartos woodii growing in Durban Botanic Gardens. photograph © Richard Boon 60 INTERNATIONAL DENDROLOGY SOCIETY TREES were collected for the Durban Botanic Gardens and for the Royal Botanic Gardens at Kew and a private nurseryman in the south of England. (It was described in the Gardeners’ Chronicle in 1908.) In 1907 John Wylie, an assistant to Medley Wood and curator of the Durban Botanic Gardens, collected two of the large trunks and planted them in the Durban Botanic Garden. In 1916 the last surviving stem was removed and was planted in Pretoria. All efforts to locate more plants – and female plants – in the original location have failed. However, hundreds of offshoots have been grown and distributed around the world, so the plant is known outside of South Africa. This is a distinctive species. The original plants stand about 6m tall, with a stately, erect stem which is broad and buttressed at the base. This buttressed stem, and the spreading canopy of arching leaves, even in juvenile plants, distinguishes the species.

    VEGETATION SURVEY OF MOUNT GORONGOSA Tom Müller, Anthony Mapaura, Bart Wursten, Christopher Chapano, Petra Ballings & Robin Wild 2008 (published 2012) Occasional Publications in Biodiversity No. 23 VEGETATION SURVEY OF MOUNT GORONGOSA Tom Müller, Anthony Mapaura, Bart Wursten, Christopher Chapano, Petra Ballings & Robin Wild 2008 (published 2012) Occasional Publications in Biodiversity No. 23 Biodiversity Foundation for Africa P.O. Box FM730, Famona, Bulawayo, Zimbabwe Vegetation Survey of Mt Gorongosa, page 2 SUMMARY Mount Gorongosa is a large inselberg almost 700 sq. km in extent in central Mozambique. With a vertical relief of between 900 and 1400 m above the surrounding plain, the highest point is at 1863 m. The mountain consists of a Lower Zone (mainly below 1100 m altitude) containing settlements and over which the natural vegetation cover has been strongly modified by people, and an Upper Zone in which much of the natural vegetation is still well preserved. Both zones are very important to the hydrology of surrounding areas. Immediately adjacent to the mountain lies Gorongosa National Park, one of Mozambique's main conservation areas. A key issue in recent years has been whether and how to incorporate the upper parts of Mount Gorongosa above 700 m altitude into the existing National Park, which is primarily lowland. [These areas were eventually incorporated into the National Park in 2010.] In recent years the unique biodiversity and scenic beauty of Mount Gorongosa have come under severe threat from the destruction of natural vegetation. This is particularly acute as regards moist evergreen forest, the loss of which has accelerated to alarming proportions.

  • A Survey of Floral Structure in Drypetes Vahl (Putranjivaceae) and Related Genera
    A survey of floral structure in Drypetes Vahl (Putranjivaceae) and related genera J. P Tesh Submitted 20.08.2012 Image from Keay, R.W.J. 1958. Scytopetalaceae - Umbelliferae. In Hutchinson, J., Dalziel, JE, eds . Flora of West Tropical Africa (Revised) Thesis submitted in partial fulfilment for the MSc in the Biodiversity and Taxonomy of Plants Abstract The pan-tropical Drypetes Vahl is a genus of 225 species of predominantly understorey rain forest trees recently segregated from Euphorbiaceae Juss. s.l . and placed within Putranjivaceae Meisn. with Putranjiva and Sibangea . Generic limits within Putranjivaceae remain unclear, notably between Drypetes and Sibangea . Within Drypetes rates of species discovery are high and yet the genus is somewhat neglected in the literature and many herbarium samples remain undetermined. Using herbarium material, this study examined approximately one third of the known species. Consistent floral characters that separate the three genera in Putranjivaceae are sepal shape, aestivation and persistence; stamen and locule numbers; ovary shape; the form of the stigma and the presence or absence of an intrastaminal nectiferous disk. Drypetes exhibits variability in floral characters: stamen number and placement is notably labile, and locule numbers, stigma and disk shapes are variable. Geographical differences in floral characters emerge, but conclusions are tentative in view of the restricted sampling. Limited phylogenetic studies hypothesise that Sibangea is nested within a clade of African Drypetes which argues for further study of this interesting, but neglected, group. Key words: Malpighiales; Euphorbiaceae; Putranjivaceae; Drypetes ; Sibangea ; Putranjiva ; placement; floral morphology; geographical differences; herbarium collections.
