Box 722, Somerset West 7129, South Africa Department of Chemistry, The University of Adelaide, Adelaide, Australia 1 ABSTRACT Aims There are major knowledge gaps in understanding the translocation leading from nickel uptake in the root to accumulation in other tissues in tropical nickel hyperaccumulator plant species. This study focuses on two species, Rinorea cf. bengalensis and Rinorea cf. javanica and aims to elucidate the similarities and differences in the distribution of nickel and physiologically relevant elements (potassium, calcium, manganese and zinc) in various organs and tissues. Methods High-resolution X-ray fluorescence microscopy (XFM) of frozen-hydrated and fresh- hydrated tissue samples and nuclear microprobe (micro-PIXE) analysis of freeze-dried samples were used to provide insights into the in situ elemental distribution in these plant species. Results This study has shown that the distribution pattern of nickel hyperaccumulation is typified by very high levels of accumulation in the phloem bundles of roots and stems. -

Berkheya purpurea and B. multijuga reach high into the mountains of the Drakensberge and, accordingly, are adapted to cold and frost. With their conspicuous coloration and im- pressive large flower heads they are most suitable as ornamental herbaceous perennials. Zusammenfassung Südafrika ist das Hauptverbreitungsgebiet der Gattung Berkheya. Berkheya purpurea und B. multijuga dringen bis in die küh- len Gebirgsregionen der Drakensberge vor und verfügen daher über eine entsprechende Kälte- und Frosttoleranz. Ihre auffal- lend gefärbten Korbblüten von beachtlicher Größe machen sie für den Staudengarten interessant. 1. Einleitung Buschland (Fynbos) in tieferen Lagen.

Insights Into the Evolution of the Tribe Arctoteae (Compositae: Subfamily Cichorioideae S.S.) Using Trnl-F, Ndhf, and ITS

Funk*, Raymund Chan2 & Sterling C. Keeley2 1 U.S. National Herbarium, Smithsonian Institution MRC 166, P.O. Box 37012, Washington D.C. 20013 U.S.A. [email protected] (author for correspondence) 2 Department of Botany, University of Hawaii at Manoa, Hawaii 96822, U.S.A. [email protected]; ster- ling@hawaii. edu Compositae (Asteraceae) are the largest flowering plant family (23,000 to 30,000 species) and its members are found throughout the world in both temperate and tropical habitats. The subfamilies and tribes of Compositae remained relatively constant for many years; recent molecular studies, however, have identified new subfa- milial groups and identified previously unknown relationships. Currently there are 35 tribes and 10 subfami- lies (Baldwin & al., 2002; Panero & Funk, 2002). Some of the tribes and subfamilies have not been tested for monophyly and without a clear understanding of the major genera that form each tribe and subfamily, an accu- rate phylogeny for the family cannot be reconstructed. The tribe Arctoteae (African daisies) is a diverse and interesting group with a primarily southern African distribution (ca. 17 genera, 220 species). They are espe- cially important in that most of the species are found in the Cape Floral Kingdom, the smallest floral kingdom and the subject of intense conservation interest. Arctoteae are part of the monophyletic subfamily Cichorioideae s.s. Other tribes in the subfamily include Eremothamneae, Gundelieae, Lactuceae, Liabeae, Moquineae, and Vernonieae, and these were all evaluated as potential outgroups. -

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.
