Abstract Loganiaceae belongs to the Order Gentianales which consists of the families Apocynaceae, Gelsemiaceae, Loganiaceae, Gentianaceae and Rubiaceae. Several Herbaria samples were studied prior to collection from Forest Reserves and National Parks in Nigeria, Republic of Benin and Ghana – with the aid of collection bags, cutlass, secateurs and ropes. Plants parts, both vegetative and reproductive were assessed with the aid of meter rule and tape rule in their natural environment and in the laboratory. Strychnos species collected were 47 individuals; 35 species were adequately identified. Anthocleista genus consists of nine species, Mostuea - three species while Nuxia, Spigelia and Usteria were monotypic genera. The leaf surfaces within the family are: hirsute, pilose, pubescent, tomentose and glabrous as found in Mostuea hirsuta, Strychnos phaeotricha, Strychnos innocua, Strychnos spinosa and members of Anthocleista species respectively. Morphological characters show 10 clusters at threshold of 47 % similarity.

  • Chapter One 1.0 Introduction and Background to The
    CHAPTER ONE 1.0 INTRODUCTION AND BACKGROUND TO THE STUDY Loganiaceae is a family of flowering plants classified in the Order Gentianales (Bendre, 1975). The family was first suggested by Robert Brown in 1814 and validly published by von Martius in 1827 (Nicholas and Baijnath, 1994). Members habits are in form of trees, shrubs, woody climbers and herbs. Some are epiphytes while some members are furnished with spines or tendrils (Bendre, 1975). They are distributed mainly in the tropics, subtropics and a few in temperate regions (Backlund et al., 2000). Earlier treatments of the family have included up to 30 genera, 600 species (Leeuwenberg and Leenhouts, 1980; Mabberley, 1997) but were later reduced to 400 species in 15 genera, with some species extending into temperate Australia and North America (Struwe et al., 1994; Dunlop, 1996; Backlund and Bremer, 1998). Morphological studies have demonstrated that this broadly defined Loganiaceae was a polyphyletic assemblage and numerous genera have been removed from it to other families (sometimes to other Orders), e.g. Gentianaceae, Gelsemiaceae, Plocospermataceae, Tetrachondraceae, Buddlejaceae, and Gesneriaceae (Backlund and Bremer, 1998; Backlund et al., 2000). The family has undergone numerous revisions that have expanded and contracted its circumscription, ranging from one genus at its smallest (Takhtajan, 1997; Smith et al., 1997) to 30 at its largest (Leeuwenberg and Leenhouts, 1980). One of the current infrafamilial classifications contains four tribes: Antonieae Endl., Loganieae Endl., Spigelieae Dum. (monotypic), and Strychneae Dum. (Struwe et al., 1994). The tribes Loganieae and Antonieae are supported by molecular data, but Strychneae is not (Backlund et al., 2000).

    AN INVESTIGATION OF ENVIRONMENTAL KNOWLEDGE AMONG TWO RURAL BLACK COMMUNITIES IN NATAL Submitted in partial fulfIlment of the requirements for the Degree of MASTER OF EDUCATION of Rhodes University by CYNTHIA SIBONGISENI MTSHALI February 1994 . , I i ABSTRACT This study elicits and documents knowledge of the natural environment amongst two rural Black communities in Natal namely, the districts of Maphumulo and Ingwavuma.Twenty members of these communities who are older than 60 years of age were interviewed, as older people are considered by the researcher to be important repositories of environmental knowledge. This study records a variety of animals hunted in these communities and discusses various activities associated with this activity. It examines the gathering and the use of wild edible plants like fruits and spinach, and of wild plants alleged to have medicinal value. It reviews indigenous knowledge related to 1 custom beliefs and prohibitions as well as traditional laws associated .with animals an9 trees. It also considers how this knowledge can contribute towards the development of Environmental Education in South Africa.

  • Use and Management of Homegarden Plants in Zvishavane District, Zimbabwe
    Tropical Ecology 54(2): 191-203, 2013 ISSN 0564-3295 © International Society for Tropical Ecology www.tropecol.com Use and management of homegarden plants in Zvishavane district, Zimbabwe ALFRED MAROYI * Biodiversity Department, School of Molecular and Life Sciences, University of Limpopo, Private Bag X1106, Sovenga 0727, South Africa Abstract: This study was aimed at documenting use and management of plant species growing in homegardens in Zvishavane district, Zimbabwe. The findings of this study were derived from qualitative and quantitative data collected from 31 homegardens in Zvishavane district between March and December 2009. The study documented information on management of plants growing in homegardens; their numbers, composition and uses. Household interviews and homegarden surveys revealed that 73 species were important to local livelihoods. Vegetables, fruits, ornamentals and medicines were the most important use categories. Among 73 plant species growing in homegardens, 52 species were cultivated and the rest were non-crop species. Cultivated species were actively managed but the management of non-crop species was passive (i.e. were tolerated and protected). These results revealed that homegardens satisfy various household needs such as food, ornamentals, medicines, building materials, religious and ceremonial uses. Resumen: El objetivo de este estudio fue documentar el uso y el manejo de especies vegetales que crecen en huertos familiares en el distrito Zvishavane, Zimbabue. Los hallazgos de este estudio se derivan de datos cualitativos y cuantitativos recolectados en 31 huertos familiares entre marzo y diciembre de 2009. El estudio documentó información sobre el manejo de plantas que crecen en huertos familiares, sus números, composición y usos.

    Marketing of Indigenous Fruits in Zimbabwe Vom Fachbereich Gartenbau der Universität Hannover zur Erlangung des akademischen Grades eines Doktors der Gartenbauwissenshaften - Dr. rer. Hort.- genehmigte Dissertation von Tunu Ramadhani Geboren am 16.11.1960, in Kibaha, Tanzania 2002 Referent: Prof. Dr. Erich Schmidt Institute of Horticultural Economics University of Hannover Koreferent: Prof. Dr. Dr. W. Manig Institute of Rural Development University of Göttingen Date of promotion: June 17, 2002 Fachbereich Gartenbau Universität Hannover By Tunu Ramadhani Marketing of Indigenous Fruits in Zimbabwe ABSTRACT Poverty, food insecurity and unsustainable use of natural resources are being blamed for the setback of African development. Research on the domestication of indigenous fruits, conducted by the International Centre for Research in Agroforestry (ICRAF) is among the several attempts to improve the livelihood strategies of the poor communities to attain food security, improve nutrition, increase cash income while conserving the environment. However, the research initiative is being limited by lack of baseline information on the existing production-to-consumption system. This study aims at describing the market structure, conduct and performance of Uapaca kirkiana and Strychnos cocculoides indigenous fruits, including the institutions guiding the management of the trees and use of the fruits. Also, intents to evaluate the demand of the fruits by assessing consumer’s attitudes, preferences and willingness to pay, and finally suggest on improvements. The study was conducted in Murehwa and Gokwe production and marketing sites, Mbare central market, City Botanical gardens and Westgate shopping centre. Data was collected by a review and analysis of secondary information, Rapid Market Appraisal, formal surveys and conjoint experiment, and analysed using descriptive statistics and advanced multivariate methods.

Originally these substances have been prepared by cooking the plant bark with water and thickening the result to a paste. The residue, a brown resinous paste with a bitter smell is used by indigenous people for arrow poisons. In the botanical system the genus Strychnos is divided in three groups: 1) One group from Central and South America with 74 species 2) Another group from Asia, Australia and Polynesia with 44 species 3) A remaining group of 75 species. Among these species Strychnos spinosa can be included into the third group. In Tropical and Southern Africa it is used as hunting venom. 28 synonyms are known (8). The plant is growing in open regions, not in rain forests, as a tree up to 45 m heighth or as a climbing scrub, heavily branched. The canopy is flattish and irregular. Leaves are dark green and – glossy, ovate or elliptic, 5.5 7.5 cm in diameter, turning yellow in autumn. Flowers are greenish white in dense heads at the end of branches during September - February.
