E-mail [email protected] Received: 17 July 2015 Returned for revision: 1 September 2015 Accepted: 23 December 2015 Published electronically: 24 March 2016 Background and Aims Obdiplostemony has long been a controversial condition as it diverges from diploste- mony found among most core eudicot orders by the more external insertion of the alternisepalous stamens. In this paper we review the definition and occurrence of obdiplostemony, and analyse how the condition has impacted on floral diversification and species evolution. Key Results Obdiplostemony represents an amalgamation of at least five different floral developmental pathways, all of them leading to the external positioning of the alternisepalous stamen whorl within a two-whorled androe- cium. In secondary obdiplostemony the antesepalous stamens arise before the alternisepalous stamens. The position of alternisepalous stamens at maturity is more external due to subtle shifts of stamens linked to a weakening of the alternisepalous sector including stamen and petal (type I), alternisepalous stamens arising de facto externally of antesepalous stamens (type II) or alternisepalous stamens shifting outside due to the sterilization of antesepalous sta- mens (type III: Sapotaceae).

  • The Riparian Vegetation of the Hottentots Holland Mountains, SW Cape
    The riparian vegetation of the Hottentots Holland Mountains, SW Cape By E.J.J. Sieben Dissertation presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy at the University of Stellenbosch Promoter: Dr. C. Boucher December 2000 Declaration I the undersigned, hereby declare that the work in this dissertation is my own original work and has not previously, in its entirety or in part, been submitted at any University for a degree. Signature Date Aan mijn ouders i Summary Riparian vegetation has received a lot of attention in South Africa recently, mainly because of its importance in bank stabilization and its influence on flood regimes and water conservation. The upper reaches have thus far received the least of this attention because of their inaccessibility. This study mainly focuses on these reaches where riparian vegetation is still mostly in a pristine state. The study area chosen for this purpose is the Hottentots Holland Mountains in the Southwestern Cape, the area with the highest rainfall in the Cape Floristic Region, which is very rich in species. Five rivers originate in this area and the vegetation described around them covers a large range of habitats, from high to low altitude, with different geological substrates and different rainfall regimes. All of these rivers are heavily disturbed in their lower reaches but are still relatively pristine in their upper reaches. All of them are dammed in at least one place, except for the Lourens River. An Interbasin Transfer Scheme connects the Eerste-, Berg- and Riviersonderend Rivers. The water of this scheme is stored mainly in Theewaterskloof Dam.

    Persoonia 25, 2010: 32– 49 www.persoonia.org RESEARCH ARTICLE doi:10.3767/003158510X538371 Phytophthora taxa associated with cultivated Agathosma, with emphasis on the P. citricola complex and P. capensis sp. nov. C.M. Bezuidenhout1, S. Denman 2, S.A. Kirk 2, W.J. Botha3, L. Mostert 4, A. McLeod4 Key words Abstract Agathosma species, which are indigenous to South Africa, are also cultivated for commercial use. Re- cently growers experienced severe plant loss, and symptoms shown by affected plants suggested that a soilborne avocado disease could be the cause of death. A number of Phytophthora taxa were isolated from diseased plants, and this buchu paper reports their identity, mating type, and pathogenicity to young Agathosma plants. Using morphological and fynbos sequence data seven Phytophthora taxa were identified: the A1 mating type of P. cinnamomi var. cinnamomi, P. cin- glucose-6-phosphate isomerase namomi var. parvispora and P. cryptogea, the A2 mating type of P. drechsleri and P. nicotianae, and two homothallic isozymes taxa from the P. citricola complex. The identity of isolates in the P. citricola complex was resolved using reference malate dehydrogenase isolates of P. citricola CIT groups 1 to 5 sensu Oudemans et al. (1994) along with multi-locus phylogenies (three pathogenicity nuclear and two mitochondrial regions), isozyme analyses, morphological characteristics and temperature-growth root-rot studies. These analyses revealed the isolates from Agathosma to include P. multivora and a putative novel species, taxonomy P. taxon emzansi. Furthermore, among the P. citricola reference isolates the presence of a new species was revealed, described here as P. capensis.

  • Kirstenbosch NBG List of Plants That Provide Food for Honey Bees
    Indigenous South African Plants that Provide Food for Honey Bees Honey bees feed on nectar (carbohydrates) and pollen (protein) from a wide variety of flowering plants. While the honey bee forages for nectar and pollen, it transfers pollen from one flower to another, providing the service of pollination, which allows the plant to reproduce. However, bees don’t pollinate all flowers that they visit. This list is based on observations of bees visiting flowers in Kirstenbosch National Botanical Garden, and on a variety of references, in particular the following: Plant of the Week articles on www.PlantZAfrica.com Johannsmeier, M.F. 2005. Beeplants of the South-Western Cape, Nectar and pollen sources of honeybees (revised and expanded). Plant Protection Research Institute Handbook No. 17. Agricultural Research Council, Plant Protection Research Institute, Pretoria, South Africa This list is primarily Western Cape, but does have application elsewhere. When planting, check with a local nursery for subspecies or varieties that occur locally to prevent inappropriate hybridisations with natural veld species in your vicinity.

  • A Phylogeny of the Rutaceae and a Biogeographic Study of Its Subfamily Aurantioideae
    A phylogeny of the Rutaceae and a biogeographic study of its subfamily Aurantioideae Thomas Schwartz Supervisor Bernard Pfeil Degree project for Master of Science In Systematics and Biodiversity, Biology 60 hec Department of Plant and Environmental Science University of Gothenburg Abstract The Rutaceae classification is complex and has undergone several changes. In addition to morphological studies, phylogenetic inference using molecular data has also led to classification changes. Thus far only chloroplast data and ITS have been used, sometimes combined with morphology to infer the phylogeny. This study adds information from a low copy nuclear gene to test the existing phylogenetic hypothesis using a species tree framework. A biogeographic study was also performed on the Aurantioideae subfamily. A pilot study looked at the choice of genes, followed by testing and evaluation of several methods for extraction of Rutaceae DNA. Thereafter, a new method for efficient separation of alleles and paralogues was examined. The sequences obtained were analysed for recombination, positive selection and hybridisation. Trees for three loci (chloroplast, nuclear HYB and MDH) were made using MrBayes and BEAST, and a species tree was constructed with *BEAST. The *BEAST species tree is used as a template for a biogeographic study with the Lagrange geographic range likelihood analysis. A Bayesian biogeographic study is also performed using a Bayesian discrete biogeographical mode (an addition to BEAST). The results are then compared with previous studies, corroborating some and rejecting others. Sammanfattning Rutace-familjens struktur är komplex och föränderlig. Förutom morfologiska studier har även fylogenetiska studier använts för att få ordning i den. Hittills har man endast tittat på kloroplastgener och ribosom-DNA, i enstaka fall i kombination med morfologiska karaktärer.
