  • The Role of Phytotoxic and Antimicrobial Compounds of Euphorbia Gummifera in the Cause and Maintenance of the Fairy Circles of Namibia
    The role of phytotoxic and antimicrobial compounds of Euphorbia gummifera in the cause and maintenance of the fairy circles of Namibia by Nicole Galt Submitted in partial fulfillment of the requirements for the degree Magister Scientiae Department of Plant and Soil Sciences Faculty of Natural and Agricultural Sciences University of Pretoria Pretoria Supervisor: Prof. J.J.M. Meyer March 2018 i The role of phytotoxic and antimicrobial compounds of Euphorbia gummifera in the cause and maintenance of the fairy circles of Namibia by Nicole Galt Department of Plant and Soil Sciences Faculty of Natural and Agricultural Sciences University of Pretoria Pretoria Supervisor: Prof. J.J.M. Meyer Degree: MSc Medicinal Plant Science Abstract Fairy circles (FC) are unexplained botanical phenomena of the pro-Namib desert and parts of the West Coast of South Africa. They are defined as circular to oval shaped anomalies of varying sizes that are left bereft of vegetation. Even though there are several distinctly different hypotheses that have aimed to explain the origin of fairy circles, none have done so to satisfaction of the scientific community. The aim of this study was to determine if phytotoxic and antibacterial properties of a co-occurring Euphorbia species, E. gummifera plays a role in the creation of fairy circles. Representative soil samples (from inside-, outside fairy circles and underneath dead E. gummifera plants) and plant samples (aerial ii parts of E. gummifera and intact grasses, Stipagrostis uniplumis) were collected from the area. The collected samples were used for a several biological assays. A soil bed bio-assay was done using the three collected soil types.

    THE BIOLOGY, ECOLOGY AND CONSERVATION OF Euphorbia clivicola IN THE LIMPOPO PROVINCE, SOUTH AFRICA MASTER OF SCIENCE IN BOTANY S.I. CHUENE 2016 THE BIOLOGY, ECOLOGY AND CONSERVATION OF Euphorbia clivicola IN THE LIMPOPO PROVINCE, SOUTH AFRICA BY SELOBA IGNITIUS CHUENE A DISSERTATION SUBMITTED IN FULFILMENT FOR THE DEGREE OF MASTER OF SCIENCE IN BOTANY FACULTY OF SCIENCE AND AGRICULTURE, SCHOOL OF MOLECULAR AND LIFE SCIENCES, DEPARTMENT OF BIODIVERSITY AT THE UNIVERSITY OF LIMPOPO SUPERVISOR: PROF. M.J. POTGIETER CO-SUPERVISOR: MR. J.W. KRUGER (LEDET) 2016 LIMPOP OF O U TY NIVERSI Faculty of Science and Agriculture ABSTRACT The need to conduct a detailed biological and ecological study on Euphorbia clivicola was sparked by the drastic decline in the sizes of the Percy Fyfe Nature Reserve (Mokopane) and Radar Hill (Polokwane) populations, coupled with the discovery of two new populations; one in Dikgale and another in Makgeng village. The two newly (2012) discovered populations lacked scientific data necessary to develop an adaptive management plan. This study aimed to conduct a detailed biological and ecological assessment, in order to develop an informed management and monitoring plan for the four populations of E. clivicola. This study entailed a demographic investigation of all populations and an inter- population genetic diversity comparison so as to establish the relationship between all populations of E. clivicola. The abiotic and biotic interactions of E. clivicola were examined to determine the intrinsic and extrinsic factors causing the decline in the Percy Fyfe Nature Reserve and Radar Hill population sizes. Fire as one of the abiotic factors was observed to be beneficial to E.

    2021/09/25 08:03 1/10 Espostoa Br.& R. Espostoa Br.& R. Cet article est basé sur l'original écrit par Graham Charles et publié dans le British Cactus and Succulent Journal 17(2): 69-79 (1999). Vous en trouverez une traduction sur le Cactus Francophone : Espostoa Br.& R. Il est ici modifié et corrigé à la lumière de nouvelles découvertes. Notez que dans l'article original, la fig 1. à la page 68 a été incorrectement légendée. On doit lire “Espostoa melanostele dans le Canyon Tinajas, près de Lima GC157.04” Although cerei are not the most popular cacti for growers restricted by cultivation in glasshouses, almost all collections have at least one representative of this beautiful genus. Most species are easy to cultivate and the hairy stems of many species make them an attractive addition to any collection, even in a small glasshouse. In pots, they are slower growing than many cerei, a factor which also makes them good show plants, frequently seen winning the Cereus class. For exhibitors, those species with stems covered with white hair catch the judge's eye. The hair can also hide minor blemishes on the stem which would more likely get spotted and count against other less covered species! In keeping with the fashionable trend towards the broader concept of genera, Espostoa has been expanded in recent years to include species previously included in the separate genera Pseudoespostoa Backbg., Thrixanthocereus Backbg. and Vatricania Backbg. Recent molecular studies have shown that Vatricania is not an Espostoa and so it will be excluded from this revised article.

    13. ROCKERY IX This feature runs in a North-South direction from near the Western end of Rockery VIII. It is a small feature, 21 meter long and about 11 meters wide at the middle. On this feature are grown plants belonging to the collection of the late SHRI O. P. BANSAL, who was a keen plant grower. For several years he was associated with the Rose Society of India. In his later years he took to growing cacti. He expired in 1994, when be was actively involved in the activities of the National Cactus and Succulent Society of India, Chandigarh. After his sudden death in 1994 the family expressed the desire to donate the plants to this Garden. So after building Rockery VIII for MR. G. C. JAIN, this rockery came into being. MR BANSAL had a small collection, but quite a large number were big 175 specimen plants. Most remarkable were three mature plants of Melocactus maxonii with large cephalium, big groups of Coryphantha elephantidens, and several large Ferocactus herrerae. Out of the three big Melocacti, one still survives near the Northern end. The others did not survive long. Now several younger plants have been planted alongside this specimen. Starting from the Northern end there is an Agave americana variegated plant. In the background of this rockery there are several large Ritterocereus pruinosis, Yucca aloefolia, Kalanchoe behariensis, Aloe arborescens and some Agaves. There are three Opuntia mamillata fa. monstrose plants on this feature. A large Espostoa lanata is near the Northern end. There is a larger plant of Napolea cochenillifera.

Email: [email protected] Manuscript received 19th August 2019 Abstract: Espostoa (Vatricania) guentheri is a peculiar putative Espostoa, having some traits in common with Espostoa sensu stricto (cephalia in which many or most epidermal cells produces a spine, bristle, or trichome), some traits in common with Thrixanthocereus (cephalia with bristles instead of hairs; patches of epidermal cells in the cephalium that lack spines, bristles, hairs or trichomes), and some unique traits (gradual transition to cephalium formation; disjunct habitat). Gradual cephalium formation in E. guentheri is common, but not universal, which might be either because Vatricania is not closely related to Espostoa or that Vatricania is of hybrid origin. E. guentheri may have a pseudocephalium, rather than a true cephalium, with the reproductive part of shoots in subgenus Vatricania being morphologically intermediate between those of subgenus Espostoa and subgenus Thrixanthocereus. Keywords: cephalium, Espostoa, disjunct species, hybrid origin, pseudocephalium, Thrixanthocereus, Vatricania INTRODUCTION Previously (Gorelick, 2016: 118), I defined a cephalium as: part of a cactus shoot arising directly from the shoot apical meristem, with the cephalium composed of confluent areoles from which flow- ers originate, bearing copious spines and trichomes, and underlain by a thick periderm in lieu of an even thicker cortex. Bristles and hairs on flowering parts are longer than those on non-flowering parts.
