The local people have a long history of traditional plant usage for medicinal purposes. Despite the increasing acceptance of traditional medicine in Zimbabwe, this rich indigenous knowledge is not adequately documented. Documentation of plants used as traditional medicines is needed so that the knowledge can be preserved and the utilized plants conserved and used sustainably. The primary objective of this paper is to summarize information on traditional uses of medicinal plants in south-central Zimbabwe, identifying research gaps and suggesting perspectives for future research. Methods: This study is based on a review of the literature published in scientific journals, books, reports from national, regional and international organizations, theses, conference papers and other grey materials. Results: A total of 93 medicinal plant species representing 41 families and 77 genera are used in south-central Zimbabwe. These plant species are used to treat 18 diseases and disorder categories, with the highest number of species used for gastro-intestinal disorders, followed by sexually transmitted infections, cold, cough and sore throat and gynaecological problems. Shrubs and trees (38% each) were the primary sources of medicinal plants, followed by herbs (21%) and climbers (3%).

  • Plastid Genomes of the North American Rhus Integrifolia-Ovata Complex and Phylogenomic Implications of Inverted Repeat Structural Evolution in Rhus L
    Plastid genomes of the North American Rhus integrifolia-ovata complex and phylogenomic implications of inverted repeat structural evolution in Rhus L. Craig F. Barrett Department of Biology, West Virginia University, Morgantown, WV, USA ABSTRACT Plastid genomes (plastomes) represent rich sources of information for phylogenomics, from higher-level studies to below the species level. The genus Rhus (sumac) has received a significant amount of study from phylogenetic and biogeographic perspectives, but genomic studies in this genus are lacking. Rhus integrifolia and R. ovata are two shrubby species of high ecological importance in the southwestern USA and Mexico, where they occupy coastal scrub and chaparral habitats. They hybridize frequently, representing a fascinating system in which to investigate the opposing effects of hybridization and divergent selection, yet are poorly characterized from a genomic perspective. In this study, complete plastid genomes were sequenced for one accession of R. integrifolia and one each of R. ovata from California and Arizona. Sequence variation among these three accessions was characterized, and PCR primers potentially useful in phylogeographic studies were designed. Phylogenomic analyses were conducted based on a robustly supported phylogenetic framework based on 52 complete plastomes across the order Sapindales. Repeat content, rather than the size of the inverted repeat, had a stronger relative association with total plastome length across Sapindales when analyzed with phylogenetic least squares regression. Variation at the inverted repeat boundary within Rhus was striking, resulting in major shifts and independent gene losses. 10 February 2020 Submitted Specifically, rps19 was lost independently in the R. integrifolia-ovata complex and in Accepted 17 May 2020 Published 16 June 2020 R.

(Meliaceae- Cedreloideae). Adansonia, sér. 3, 36 (2): 335-349. http://dx.doi.org/10.5252/a2014n2a13 ABSTRACT Ant-plant interactions mediated by special structures provided by plants such as domatia, extrafloral nectaries (EFNs) and food bodies, are very frequent in tropical ecosystems. To understand why ants are frequently encountered on most species of Carapa Aubl. (Meliaceae), we investigated the presence of ex- tranuptial nectaries (ENNs) in all 27 species of the genus, spanning its entire distributional range in tropical Africa and America. We report for the first time in the genus the occurrence of extrafloral nectaries (at the base of the petiole, along the rachis of the pinnately compound leaf, on bracts) petaline nectaries (on the outer surface of petals), and pericarpial nectaries (on the surface of fruits), and confirm the presence of nectaries on leaflets in Carapa. Petiolar nectaries are the most common, occurring in 85% of the species. Nectaries were mainly active in young developing plant organs. Ants were observed foraging on exu- dates from these nectaries. e secretions from these glands help to explain the KEY WORDS abundance of ants on Carapa trees.

This comprehensive review summarizes the ethnobotanical uses and chemistry of 12 South African species, belonging to six genera: Ekebergia, Nymania, Entandrophragma, Pseudobersama, Trichilia, and Turraea. Eight of the species have ethnomedicinal records, clas- sified into 17 major disease categories. The ethnomedicinal uses comprise 85 ailments dominated by gastrointestinal complaints, followed by gynaecological and obstetrics related problems. Chemical records were found for 10 species, which describe nine classes of compounds. In nearly all South African Meliaceae, limonoids are the predominant constituents while triterpenes, sterols, and coumarins are also common. The widest range of use-records and medicinal applications are found with the two most chemically diverse species, Ekebergia capensis and Trichilia emetica. Of the chemical compounds identified in the various plant organs of the 10 species of South African Meliaceae for which data are available, 42% was found in bark and 17% in seeds. Roots represent Citation: Oyedeji-Amusa, M.O.; 35% and bark 33% of the organs that are used medicinally, and they are typically prepared as Sadgrove, N.J.; Van Wyk, B.-E.

  • Title: Evaluating an Insect Agent for Biological Control of Christmas Berry
    Title: Evaluating an insect agent for biological control of Christmas berry (Schinus terebinthifolius) in Hawai`i Organizations: USDA Forest Service, USDA Agricultural Research Service Award: $25,000 Introduction: The USDA Forest Service Institute of Pacific Islands Forestry researches natural enemies of invasive plants for their potential use in management of Hawaiian forest weeds. We were awarded funds by HISC and the Hawaii Watershed Partnerships Program for host specificity testing of a potential natural enemy for Christmas berry (Schinus terebinthifolius). Christmas berry is a major pest of mesic ranchland, natural areas and archaeological sites, and a high priority target for biological control in Hawai`i. Dr. Gregory Wheeler of the USDA- ARS Invasive Plant Research Laboratory (IPRL) in Fort Lauderdale, Florida has been contracted to test a Brazilian thrips insect, Pseudophilothrips ichini, to determine if it will be safe for release in Hawai`i for control of Christmas berry Pseudophilothrips ichini larvae and (also called Brazilian pepper in Florida). The IPRL is testing approximately 35 adults feed on Christmas berry species of crop plants, native plants and culturally important plants that occur in stems and leaves Hawai`i, mostly within the order Sapindales, to which Christmas berry belongs. Achievements in FY13 Feeding and reproduction of the P. ichini thrips has been evaluated on 29 plant species of importance to Hawai`i, and most tests are complete with 4 or 5 replicate plants tested (Table 1). The test plant list includes the closest relatives of the weed that occur in Hawai`i. Tests are under no-choice conditions (insects faced with starvation): 20 adult thrips are allowed to feed and reproduce on each test plant, and the next generation of adults are counted.

  • Effects of Logging on Environmental Factors, Natural Regeneration, and Distribution of Selected Mahogany Species in Budongo Forest Reserve, Uganda
    EFFECTS OF LOGGING ON ENVIRONMENTAL FACTORS, NATURAL REGENERATION, AND DISTRIBUTION OF SELECTED MAHOGANY SPECIES IN BUDONGO FOREST RESERVE, UGANDA By JOSEPH B. BAHATI DEPARTMENT OF FOREST BIOLOGY AND ECOSYSTEMS MANAGEMENT FACULTY OF FORESTRY AND NATURE CONSERVATION MAKERERE UNIVERSITY A THESIS SUBMITTED IN CANDIDATURE FOR THE DEGREE OF DOCTOR OF PHILOSOPHY OF MAKERERE UNIVERSITY KAMPALA 2005 ABSTRACT This study explored some of the basic environmental factors that affect the natural regeneration of four mahogany species existing in the Budongo Forest Reserve, Uganda. The four species studied are: Khaya anthotheca, Entandrophragma cylindricum, E. utile and E. angolense. For each species, the biology, ecophysiology, silviculture and management are reviewed. Diverse published reports were critically reviewed and efforts made to highlight their contributions and identify knowledge gaps. Whereas forest understorey light is emphasized as the major hindrance to tropical natural forest regeneration, this study also investigated the effects of past logging in the Budongo forest reserve on soil factors and microenvironments (illumination, photosynthetically active radiation and forest temperature) and on mahogany regeneration. Three forest categories (“treatments”) including unlogged (one compartment), earlier logged (seven compartments) and later logged (three compartments) were identified from the Budongo forest main block and the two outlying forest patches (Siba and Kaniyo Pabidi). Data were collected from plots established in each compartment. A total of 258 plots were sampled. The plots were 25m x 50m each. Within each plot, mahogany seedlings, saplings and trees were sampled. From the same plots, soil samples were collected and were analyzed for texture, pH and nutrients and compared within and between treatments. Furthermore, illumination, photosynthetically active radiation (PAR) and temperature (below ground, forest floor and forest understorey-air) were evaluated to ascertain whether there were any variations in and between the three treatments.
